Where Does Sump Pump Water Come From

How Does Water Enter a Sump Pit?

Sump pumps are placed in crawl spaces and basements in a large number of homes around the country. They are very necessary for homes constructed in locations with high water tables or where basement flooding is regular. Sump pumps are often located in the lowest portion of a home and are responsible for keeping that region dry by moving water away from the area through another drainage system.

Sump Pump Basics

Sump pumps are an excellent option for a basement that floods often. A basement placed below the water table can also cause moisture, which can be remedied with the help of these products. The sump pit will be the point of entry for water into the sump pump system. From there, it is fed into the sump pump, which will pump the water away from the house to a location where it will not do any harm to the structure.

Running a Sump Pump

Ideally, a sump pump should only be activated when there is a water problem. This implies that if there is melting ice and snow, or if there is heavy rain, you should turn on the heater. Keep in mind that the pump is designed to activate when the water level in the pit climbs above a specified threshold. The pump recognizes when this occurs in the same manner that a toilet recognizes when it is time to cease filling. Both of these programs make use of floats. As a result, the pump is activated every time the float reaches a specified level in the reservoir.

A damaged float might be to blame.

Sump Pump Water

Water always chooses the path that offers the least amount of resistance. Because of this, it is not uncommon for rainwater that soaks deeply into the soil as a result of heavy rain to migrate its way through the soil and through your cement foundation. If the water table in the region is particularly high, water can also be drawn out from the earth. It is recommended that you install a sump pump if you are experiencing increasing water tables and find that your basement is becoming moist. It is possible for the water that is pumped away from your property to enter the system through a number of different pathways.

How Sump Pits Work

Sump pumps are normally housed within a sump pit or sump pits. The sump basin is a collection place where water gathers before being pushed away by the sump pump (see illustration). These pits are computer-controlled systems that may be designed in a variety of various forms, depending on the demands of the homeowner. A drain tile is one of the most often used techniques of constructing sump pits. Vertically below the ground, these perforated tiles are laid down horizontally. The slope of the drain tiles guarantees that water will gather in the areas where it is intended to be collected.

  • Another frequent technique of building a sump pit is to use PVC tubing that is 16 or 18 inches in diameter.
  • Covering the pipe with various types of gravel or broken rocks is also an option.
  • Pump failures can be caused by water entering into the pump itself, which can cause significant damage to your system.
  • Because of this, a certain amount of water will constantly remain in the sump pit.

Depending on the pit, there are varying limits for how far the water may rise before it becomes dangerous. When the water level rises over that mark, the pump will activate and remove the water out of the basement before it can do damage.

Surface Drains to Prevent Damage

Surface drains can also be employed if there is a problem with surface water. If there is any standing water in the basement, it will naturally drain into a low spot in the flooring. This type of system is effective in preventing serious water damage, such as the growth of mold or mildew. It does not, however, prevent wetness from occurring. If you want to ensure that your region is completely dry, you’ll need to employ a different approach.

Everything You Need to Know About Your Sump Pump

What better way to be reminded of the purpose of your sump pump than by abruptly walking into ankle-deep freezing water at the foot of your basement steps? It’s easy to forget about sump pumps while they’re working well, but when they fail, it’s a maintenance issue.

What Is a Sump Pump?

Sump pumps are tiny pumps that are used to divert water away from sump basins and into other areas. There are two primary types of sump pumps: submersible and axial.

  • Submersible sump pumps, which are completely submerged in your sump basin, are also available. Pedestal sump pumps are those that are positioned above the floor level on columns that extend out of the sump basin
  • They are also known as pedestal sump pumps.

Sump pumps, which were invented in 1946 by U.S. Navy electrician Karl Niedermeyer, have been a frequent fixture in American homes for decades. Until the late 1980s, most residences constructed on floodplains or below the water table were equipped with sump pumps as standard equipment. According to the United States Federal Clean Water Act, sump pumps are now required in many new construction projects. If you live in a modern home, you are likely to have a sump pump, even if you live in an arid region.

What Does a Sump Pump Do?

You most certainly have a sump basin in your basement or crawl space, which is most likely located in a corner or against an outside wall of your home (also called a sump pit). If you remove the debris cover from your sump basin and look inside, you’ll notice many holes in the wall of the basin. Each of these holes is connected to a drainage pipe as follows: Some drain pipes are derived from weeping tile pipes located outside the bottom of your home’s foundation, while others are connected to internal drainage systems located beneath the basement floor of your home.

When the amount of water reaches a specific point, your sump pump activates.

  • An overpressure sensor, which provides a signal to your pump when the water pressure in your sump pit exceeds a predetermined threshold
  • A float activator arm with a buoyant ball attached, which floats on the surface of the water when activated. When the water level in your basement reaches a specific level, your sump pump kicks in

An impeller within your pump takes water out of the sump pit and propels it up a discharge pipe using centrifugal force. The discharge pipe discharges into a body of water that is located outside your home’s foundations.

Discharge pipes should be buried at least 5 inches below the frost level in order to prevent them from freezing during the winter months. It is preferable if they can also flow downhill whenever feasible.

How Does a Sump Pump Work?

The majority of sump pumps are plugged into a home’s energy supply, while others are powered by the city’s water distribution system. Water-driven sump pumps continue to function even when the power is down, making them an excellent choice if you live in a location with a long storm season. When it comes to operating costs, though, they might be fairly expensive if your city’s municipal water rates are too high. Some sump pumps that run on alternating current include handy battery backups.

How Often Should a Sump Pump Run?

It is likely that your sump pump will be activated on a regular basis if you reside in a floodplain or if your property is below the water table. This is due to water accumulating under your foundation and flowing into your sump pit. You should expect to hear your sump pump working more during periods of heavy rain or during severe storms. Some states receive a significant amount of snow throughout the winter; if you reside in one of these regions, your sump pump will be kept quite busy while the snow and ice melt in the spring.

My Sump Pump Runs Continuously

If your sump pump continues to run indefinitely or more frequently than planned, look for broken pipes, overflowing washers, and other water-related home issues. If you are unable to locate an evident problem, examine within your sump pit. For your own safety, always remember to switch off the electricity to your pump before starting it. The sensor or float activator arm of your pump may be trapped or damaged if the water level is too low to operate. If you notice a substantial amount of water where you did not anticipate it, contact your utility provider and urge them to investigate a possible broken water main.

  • Drain lines that are frozen or obstructed
  • In the form of a soiled sump pit A sump pit that is too tiny or has collapsed There’s a seasonal underground spring that you’re not aware of

Sump pumps can fail for a variety of reasons, including insufficient capacity. If you live in a rainy climate, be certain that you have a strong pump installed and that your sump pit is large enough to hold the amount of runoff you expect on a consistent basis.

My Sump Pump Doesn’t Run

Continuous sump pump operation is the worst kind of nightmare. There is no activity from the sump pump at all. If you reside in a low-lying location and your sump pump is completely silent, you should be concerned. Eventually, water will pool in your basement, causing growing damp and mold development in the process of drying out. You’ll eventually find yourself in flood-prone region, so it’s critical to have your sump pump in working order as soon as possible. Here are some steps you can take to get started:

  • First, check to see whether the circuit breaker for your sump pump has tripped. If power is not the source of the problem, inspect the float activator arm on your pump: It’s possible that it’s stuck in the off position (remember to cut off the electricity to your pump before starting)
  • Then, clean out your sump pit of any accumulated trash or accumulation. If it is still not working, unhook your pump and remove it out of the pit
  • If it is still not working, Remove the bottom cover of your pump and inspect it for obstructions in the impeller

If none of these measures yields any results, you may want to consider replacing the float switch or pressure sensor on your pump. Is this still not working? It’s possible that it’s time to replace the pump.

How Long Does a Sump Pump Last?

In general, pedestal pumps have a longer life span than submersible pumps, although there are exceptions. They’re more noticeable, but they’re also easier to maintain, and according to industry experts, they may last for up to 30 years before needing to be replaced.

Submersible pumps are more aesthetically pleasing, but they are also more prone to failure. Submersible pumps have a lifespan of five to ten years, so plan on replacing it after that time.

What Sump Pump Do I Need?

When it comes to purchasing sump pumps, it might be difficult. The majority of individuals choose for submersible pumps or pedestal types, and they customize the features to meet their specific requirements. Following are four factors to keep in mind while looking for a sump pump system:

Choose the Right Horsepower for Your Situation

It is not always the case that more horsepower pumps are preferable. Installing a big pump if you don’t need one can increase the likelihood of it failing prematurely. Instead, choose for a more compact and energy-efficient pump. Additional Related Articles:

Select the Right Float Switch

Mechanical float activator arms are visible and easy to examine, although they do become stuck from time to time for unknown reasons. Electronic switches are more aesthetically pleasing and take up less space in your sump pit, but they are more difficult to repair.

Consider a Backup Sump Pump System

Sump pump packages, which contain backup sump pumps, are available from several retailers. Combination sump pump systems are equipped with a built-in backup. If you don’t already have one, you should consider installing a separate backup sump pump. Some pumps have sophisticated added features, such as water alarm systems, and a few of them are even Wi-Fi-connected, allowing them to send alerts to your smartphone or smart home if they have a problem. Having said that, most homeowners are quite content with basic, high-quality automated pumps.

Sump Pumps

Sump pumps are generally dependable as long as they are connected to a backup power source. A few things to keep an eye out for are listed below.

Debris in the pump

Sump pits, particularly open pits without a cover, may quickly become clogged with material. If there is an excessive amount of dirt or debris in the pump itself, the system will not function correctly and may possibly fail to work totally. If a switch becomes locked in the ON position due to debris buildup, the motor may overheat and burn out, potentially resulting in a fire.

Clogged or frozen discharge lines

The majority of sump pump systems are equipped with an air gap. Water can escape from the system through an open piece of the discharge pipe if the pipes freeze or clog, and this is what the air gap is for. Most of the time, the air gap is positioned when the discharge pipe departs the construction site. Air gaps are not always literal gaps; they can be formed by slotted pipes or vented covers, or they can take on any of a variety of shapes, including atriums, candy canes, and pipes inside pipes, among others.

According to the sort of air gap your sump pump employs, it may be more or less vulnerable to becoming blocked. While the sump pump is working, you should routinely verify your air gap to ensure that water is moving easily through it.

Wrong sized pump

If your pump’s flow rating is insufficient, it may struggle to displace all of the water entering your property, causing the motor to overheat and fail.

Missing or broken check valve

Water that is evacuated from your sump pump often travels 6-10 vertical feet before exiting your home, which is a significant amount of labor for such a little pump. Any issues with your check valves will result in an increase in back pressure on the pump, which will place additional strain on the device.

Improper connection to sewage line

Heavy rain or snowmelt can cause significant quantities of runoff to enter sewer systems, which are not built to handle this volume of water. If your home’s sump pump is linked to the sewer, it may cause an overflow of the system, resulting in a backlog of water into your basement. This link also serves as an extra point of entry for water into the system. Disconnecting your pump from the sewer system is something to think about (with input from a professional if you need to design a new outflow path).

Float switch stuck on

A float switch that has become stuck on can cause your sump pump to operate continually even when it is not needed to do so. It is possible that a jammed float switch is simply stuck. To begin, inspect the switch to determine whether any debris has been lodged in it. Remove the junk and check to see whether it begins to function correctly. Alternatively, float switches may become stuck if the pump has strayed too far from its original position, as described above. Sump pumps vibrate while they operate, and they may move themselves far enough that the float switch becomes caught on a particular object.

Not turning on

There are a variety of reasons why your sump pump isn’t working, including the following:

  • It is possible that the float switch has been stuck in the off position. Try manually elevating the float switch to check whether your pump goes on
  • If it doesn’t, it’s possible that your pump isn’t getting enough power. Check to see that it is connected into a working power outlet (you may test the outlet with anything else if necessary) and that it hasn’t tripped a breaker. Sump pumps should be connected to a separate circuit since the motor of the pump might overheat if not. It is possible for a pump to overheat if it is forced to run constantly for an extended period of time or if it is pushing more water than it is intended to handle. If your sump pump overheats frequently, it is possible that it is too tiny
  • Alternatively, the sump pump’s motor may have failed. You may need to repair the motor if your sump pump won’t run despite having enough electricity and a working switch. It’s also possible that the pump is clogged. Check the discharge pipe of the pump (which is generally positioned outside at ground level) to confirm that water is flowing properly through it. After that, disconnect the pump and check for obstructions in the intake. It is possible that you may need to remove the pump from the sump pit.

What will your home insurance provider want to know?

Fire, theft, and water damage together account for more house insurance claims than all other causes combined. In fact, the average cost of an insurance claim for a flooded basement is $43,500 dollars. A sump pump as well as a backup power system are likely to be requested by your home insurance provider as a result of these requirements. If you live in a flood-prone location, your home insurance carrier may demand that you install a sump pump before they would consider providing coverage. In addition, insurance companies frequently impose higher flooddeductibles for residences located in high-risk flood zones.

Customers who have sump pumps that are powered by a battery, on the other hand, are eligible for cheaper rates in high-risk locations.

Is sump pump failure covered by insurance?

If your sump pump fails and causes water damage to your house, your home insurance will only cover the water damage if it covers that sort of loss in its standard policy language. This is dependent on how the water enters your residence. Example: If your sump pump breaks during a thunderstorm and groundwater backs up through the sump and into your basement, your house insurance would only pay the loss to the extent that it ordinarily covers losses caused by the backing up of sewage, septic, and sump systems.

Furthermore, if your sump pump fails during an overland flooding event – such as a flood caused by a river that overflows its banks – many house insurance plans will not cover this type of damage as all, regardless of whether or not the sump pump is working correctly.

Overland flooding coverage is available as an optional endorsement from some homeowners insurance companies. Overland flood coverage is included in the majority of the policies that Square One sells.

Other commonly asked questions

The frequency at which a sump pump operates is determined by the local circumstances. Some basements are closer to the water table than others, and as a result, their sump pumps are activated more frequently in some cases. In addition, the grade on your land may force the sump pump to run even when there is just minimal rain. Following prolonged periods of heavy rain, it is usual for a sump pump to work sporadically for several days afterward. Something can be wrong with your sump pump if you believe it is running too frequently, or if it has suddenly started operating more frequently than it has previously.

  • A malfunctioning check valve has been identified. The check valve allows water to flow out, but it does not allow water to flow back in. If it’s not working properly, there may be water backing up into the sump pit, requiring the pump to work harder than it should. Check valves are typically put in the sump pit, close to the pump, to prevent flooding. A sump pump that does not have a check valve fitted
  • A discharge line that is clogged. If there is debris in the outlet pipes, the pump will have to work harder to push water through
  • A pump that is too tiny will result in increased energy consumption and decreased efficiency. Even if you are unable to identify any technical problems with your pump, it is possible that the pump is just too small for your home. Carry out the calculations from earlier on this page to see whether you require a more powerful pump
  • A change in the water table. Water tables can fluctuate over time, particularly throughout the course of a season. If the water table in your house rises above the level of your sump pit, your pump will have to work considerably harder to keep up with the demand. It’s possible that the remedy will be complicated (if it even requires a fix)
  • You’ll most likely need to consult with a sump pump specialist to see what they recommend.

How does a battery backup work for a sump pump?

It is critical to have a sump pump with a battery backup. These pumps function by automatically turning on when the main pump stops operating or is unable to keep up with the pace of water infiltration. The backup pump is not simply a battery linked to the main pump; it is a whole different pump from the primary pump. However, it is possible to purchase combination sump pumps that have both a primary and a backup pump in the same package. The vast majority of backup pumps will operate on a periodic basis to ensure that they are still in good working order.

If you discover that your backup pump (or your primary pump, for that matter) isn’t operating, take action as quickly as possible to correct the situation.

How do I know if I need a sump pump?

It’s never a bad idea to have a sump pump installed in any home that has a basement or any component of the house that is below grade (which includes the vast majority of homes in Canada). Having a sump pump installed is a must if your basement has experienced flooding in the past. In the case of flat or low-lying terrain, as well as areas that receive significant snow or rain, you should consider installing a sump pump. Whether you notice moisture in your basement, dry it out using a dehumidifier and come back a few days later to see if the problem has been resolved.

  • Given that sump pumps are quite affordable (particularly when compared to the expense of fixing water damage), most homes who have a basement should seriously consider installing one if they don’t already have one.

10 Common Mistakes Homeowners Make With Sump Pumps

A sump pump is a pump that is used to remove water that has accumulated in a sump basin that has been specifically intended to collect water, which is often located in the basement of a house or other building. There are several ways in which water can enter a sump pump: it can enter by funneling into the pump through the designated perimeter drains in a basement’s waterproofing system, or it can enter by gravity due to groundwater or rainfall if the basement happens to be below the water table level, if the basement is below the water table level.

Generally speaking, the primary function of a sump pump is to pump and discharge water away from the house, to a location where it will do less damage – typically a city storm drain or a dry well.

The pressurized water system of a home can occasionally be used to drive a pump, essentially eliminating the need for electricity altogether – albeit this is done at the price of consuming potable water, which can make them more expensive to maintain than their electrical pump equivalents.

Maintaining Your Sump Pump

It is critical to remember that a sump basin might overflow if it is not pumped on a consistent and regular basis. As a result, it is critical that you have a backup system in place for your sump pump in the event that the main power to your house is knocked out for a lengthy period of time, as is frequently the case after a major storm. Don’t forget to check out our most recent blogs, which include: What to Do When Your Sump Pump Fails and 12 Signs That It’s Time to Replace Your Sump Pump are two of the most often asked questions.

Continue reading to learn about some of the most frequent mistakes that people make when installing sump pumps, as well as how to prevent making them.

Mistake1: Letting debris get in the pump.

Check that your sump pump does not lie on any loose silt, tiny sized pebbles, or any other form of material that might easily be sucked up into the pump to prevent making this common error – since it will cause a problem. In lieu of this, use large pebbles or gravel at least the size of a dime to prevent your pipes from being blocked, which can cause the motor in your pump to fail prematurely.

Mistake2: Issues with the float switch.

A float switch is a simple device that instructs the sump pump motor to shut down when the water level falls below a certain level. Because of what it performs, your sump pump will require a large amount of room surrounding the float and switch in order for the arm to be able to freely float and descend simultaneously.

It is possible that the float will cause the pump to operate wrongly if there is insufficient space or if there is some form of impediment in the path. This might lead to your motor being damaged.

Mistake3: Errors with the check valve.

The check valve on a sump pump simply forms a barrier that stops any water from going backward into the sump pump itself. There should be an arrow written around the check value to show which way the valve should be turned when the value is checked. Check to ensure that the arrow is pointing away from the sump pump before continuing.

Mistake4: Not testing your sump pump system.

A sump pump is often required at three different degrees of “necessity,” to put it simply. When your sump pump is operating at Level 1, it is essentially running continually, even when there is little to no rainfall. Level 2 is regarded to be the “ideal” case, in which your pump does not run on a regular basis — but does so when the situation calls for it, such as during heavy rain or a storm — and then shuts off. Level 3 refers to when your pump does not operate. You must test your system on a regular basis, or at the very least once a year.

It’s simple – just fill the container with water.

Slowly pour the water into the pump (think about the rate at which rainwater may enter the pump) until the float triggers the pump to engage the motor.

If this is not the case with your system, you will need to troubleshoot any difficulties that you may be experiencing in order to determine whether or not you need repairs or replacements.

Mistake5: A broken discharge pipe.

The most dangerous aspect of a ruptured discharge pipe is that it might occur underground, making it hard to detect or detect until it is too late. And how will you know when it’s too late to do anything? It’s that moment when you step into your basement and everything is floating. Something similar like this is very certain to have occurred to someone you know at some time in their life. Is there a moral to this story? If your discharge pipes protrude from your home or if you have an underground system, you should examine them on a regular basis.

Mistake6: Someone unplugged your pump.

This one appears to be a no-brainer, yet it occurs more frequently than you may expect. Someone comes down into your basement and wants an electrical outlet for whatever reason. You provide the plug. In order to plug in such device, they unintentionally unplug your sump pump. and then forget to plug it back in again afterwards. Fortunately, this is a straightforward fix: always double-check that the sump pump has been properly reconnected. Alternatively, you could never disconnect it.

Mistake7: Failing to check for loose wiring in your system.

Another basic step that should be included in your checklist of regular system maintenance is checking for frayed or damaged cables. What would you do if you suspect that your sump pump’s cables are frayed? One sign is if your sump pump stops working all of a sudden. Unfortunately, if you don’t examine something as easy as the wiring, it’s possible that you’ll miss anything that may be a simple fix to get the pump back up and running. For the purpose of inspecting the wiring, first switch off the power to the pump at the source.

After that, turn off the pump. You should thoroughly check the pump, looking for any loose wires and replacing any that you find. Install the pump once again, reconnect the electricity, and then check to see whether the pump starts operating again.

Mistake8: Not listening to the sump pump motor.

Believe it or not, if you don’t just listen to the motor of your sump pump, you may make a lot of blunders. The outside pump will need to be checked if the motor and pump are both operating at the same time (where the water should be escaping). If there is no water flowing out of the faucet, you will need to conduct some troubleshooting. It’s possible that a water line has become clogged, or that your check valve has become stuck. Certain of them are pretty uncomplicated adjustments that you can complete on your own; but, in some cases, it is preferable to enlist the assistance of a team of pros.

Mistake9: Not recognizing when a professional needs to step in and complete any necessary repairs to your sump pump.

In the event that you have thoroughly examined your sump pump and checked all of the tiny details, and you have exhausted all other options for diagnosing any difficulties you may have identified, you should always contact a professional to begin the repairs. It is quite simple to tell whether your pump may require expert repair by just checking to see if the water is discharging correctly on a regular basis.

Sump pump – Wikipedia

With a garden hose hookup, a tiny submersible ac sump pump may be used. When water has collected in a water-collectingsumpbasin, which is typically seen in the basements of homes, anumber of pumps are used to drain the water from the basin. If the basement is below the water table level, water may enter through perimeter drains of a basement waterproofing system, funneling into the basin, or it may enter through rain or natural ground water if the basement is above the water table level. The usage of sump pumps is recommended in situations when basement flooding occurs on a regular basis, as well as in situations where the water table is above the foundation of a property.

  1. Pumps in older systems may discharge into the sanitary sewage system.
  2. Residents are encouraged to unplug and redirect sump pump output away from sanitary sewers, according to local authorities.
  3. Many homeowners have inherited their sump pump installations, and they are unaware that the pump empties into the sewage system as a result.
  4. Some pumps are powered by the home’s pressurized water supply, which eliminates the need for electricity at the price of utilizing potable water, making them potentially more expensive to maintain than electrical pumps and introducing an extra water disposal concern.
  5. Sump pumps are typically classified into two categories: pedestal and submersible.
  6. It is driven by a long, vertical extension shaft, and the impeller is housed in a scroll housing at the bottom of the pump’s casing.
  7. There is some disagreement about whether type of sump pump is the best.
  8. They are less expensive to replace and are also less difficult to remove.
  9. They are more expensive to acquire, but they are capable of collecting trash without becoming clogged.
  10. Anartesian aquifers and occasional high water tables can cause the earth to become unstable as a result of the saturation of the soil with water.
  11. These sumps are normally 10 feet or deeper in depth, and they are lined with corrugated metal tubing that has perforations or drain holes throughout them to facilitate drainage.

In addition to having electrical control systems with both visible and audible alerts, they are frequently covered to prevent debris and animals from falling in.


In the United States, modern sump pump components are standardized to meet industry standards. They are as follows:

  • A sump basin made of plastic, metal, or concrete that is approximately 2 feet (0.6 m) broad and 2 to 3 feet (0.6 to 1 m) deep, with a capacity of 15 to 25 US gallons (60 to 100 litres)
  • The following: a sump pump with a power rating of 1/3 or 1/2 horsepower (200 or 400 W), which can be either battery or mains powered (or both)

Pump selection

When choosing a sump pump, the following factors should be considered:

  • Control of the pump via an automated level switch as opposed to a manual operation Power – The motor power of a sump pump can range from a quarter horsepower to several horsepower. In the case of a sump pump, hydraulic headpressure is used to define the greatest height to which the water may be moved by the pump. For example, a sump pump with a maximum head of 15 feet (4.6 m) (also known as a shutdown head) will elevate water up to 15 feet (4.6 m) before it totally stops pumping
  • In order to provide sufficient voltage at the motor for optimal pump performance while operating a more powerful electrical motor at a distance from the main service panel, the length of the power cable should be considered. Phase and voltage – Sump pumps that are driven by alternating current are available with single-phase or three-phase induction motors rated for 110–120, 220–240, or 460 volts, depending on the model. In most residential areas, three-phase electricity is not accessible
  • But, in few cases, it is. A sort of water level sensing switch is the pressure switch, which is completely enclosed, generally within the pump body. This makes pressure switches impervious to obstacles or floating debris in the sump basin. It is possible for float switches, particularly those that are linked to the end of a short length of flexible electrical wire, to become tangled or clogged, especially when the pump is prone to movement in the basin as a result of torque effects while starting and stopping the pump. In contrast to pressure switches, which are normally factory preset and cannot be modified, float switches may be adjusted in place to control the high and low water levels in the sump basin. In addition, there is a solid state switch that makes use of field-effect technology, which will turn on and off the pump with the use of an internal switch and a piggyback plug
  • And Backup and alarm systems for mission-critical applications

Backup components

In the event that the primary sump pump fails, a backup sump pump, normally powered by batteries, can be used. A battery-powered secondary pump will be equipped with a separate battery and charger system to provide power in the event that the main power source is disrupted or lost. Alternative sump pump systems can be powered by the pressure of municipal water supplies. Ejector pumps that are driven by water have a separate pump, float, and check valve. On the sump pit wall above the regular high water mark, there is an electronic float that controls a backup pump.

When the water level in the sump increases above usual for whatever cause, the backup float in the sump is lifted, causing the backup sump pump to be activated.

Despite the fact that such ejector pumps waste water and are rather inefficient, they have the benefit of having no moving parts and providing the highest level of dependability possible.

Some battery control modules test the system on a regular basis and send out alerts when electrical components fail.


A common pedestal-type sump pump is seen in this illustration. It is necessary to keep sump basins and sump pumps in good working order. According to standard requirements, equipment should be inspected once a year. More frequency of operation of pumps owing to a higher water table, increased water drainage, or extreme weather conditions should be investigated more regularly. The fact that sump pumps are mechanical equipment means that they will eventually fail, which might result in a flooded basement and expensive repairs.

  • In order to boost performance and extend the life of a sump pump, it is necessary to thoroughly clean it.
  • These blockages can also impair the pump’s capacity to empty the sump, perhaps resulting in the sump overflowing as a result.
  • Examine the discharge line opening, if appropriate, to confirm that there are no blockages in the line before continuing.
  • Float switches are used to automatically activate the sump pump when the water level reaches a predetermined level.
  • In order to avoid the possibility of the float switch accidently resting on the pump housing and remaining on, a float guard can be installed.
  • Whenever a pedestal pump is left in standing water, it should be manually restarted every few hours, even if the level of water in the sump is not high enough to trip the float switch.

Instead, a pedestal pump that will be idle for a long period of time should be withdrawn from the sump and stored in a dry location, or the sump should be swept out so that the level of residual water is far below the lower shaft bearing (see Figure 1).

What is a Sump Pump and How Does It Work?

If you live in or work in a building that is or may be susceptible to flooding, you should consider installing a sump pump. Unfortunately, sump pumps are usually the last thing that people think of when they have a flood. Making matters worse, regular water flows are what most people think of when they think of water. There are a variety of other factors that might cause damage to your property, including seepage, drainage, storm surges, and seasonal thawing. However, even if you are unfamiliar with the concept of a sump pump, you are surely well aware of the catastrophic damage that may be caused by an uncontrolled flow of water.

It is unlikely that you are concerned about where the water in your community comes from or where it is being channelled to.

In this case, the advantages of having a sump pump and a sump pit come into play.

What Does a Sump Pump Do?

In order to properly install a sump pump, it is necessary to first determine where water tends to collect on or around your property. This is typically seen in areas where water tends to collect on your property. Your yard, cellar, or crawl area could be a good candidate for this project. Wherever there is a tendency for water to gather, your sump pump should be installed. A sump pump is often installed in a pit, which is not only the location where water has accumulated, but also the proper quantity of room to accommodate the water.

  1. This is about the amount of room required to construct your pit.
  2. However, you must ensure that the space taken up by the pit is sufficient in order to prevent flooding.
  3. Some pits have a surface area of many feet, while others have a surface area of only a foot or two.
  4. The pump, the second component of the system, is responsible for removing the waste after it has reached the pit.
  5. After all, once the water is in the pit, it will remain there until such time as something else occurs, such as the pump turning on and removing the water.
  6. Do not misunderstand what I am saying.
  7. It is for this reason that it is critical that it is constructed and operated properly.
  8. It will only function, though, if your electricity is turned on.
  9. The objective of a sump pump and pit is to ensure that water does not enter your home and to alert you if there is water present.
  10. Not only are many of today’s sump pumps completely autonomous, but many of them also have alerts built in that notify you by phone or text message if an odd scenario develops.

Through the use of software diagnostics, they can also offer you with a comprehensive picture of what is going on with your sump pump. Oh, technology is fantastic, isn’t it?

What Kind of Sump Pump Should I Get?

Despite the fact that there are several distinct types of sump pumps, they are essentially divided into two categories: pedestal and submersible. A comprehensive study of each of these categories is beyond the scope of this article and will be explored in greater depth in another, but suffice it to say that each has its own set of pros and downsides to consider. Others sump pumps are larger than others, while some are smaller. Some sump pumps are more expensive than others, depending on their features.

It all relies on what you want and what will accomplish the task you have in mind.

In any case, thanks to the large number of products available, the odds are strong that you will be able to discover a sump pump that is ideal for your particular circumstance.

How Does Water Get Into Sump Pit?

We’ll give you our word for it. Water does not enter a sump hole as a result of elfin magic. It truly flows there from wherever it happens to be coming from at any given time. It is possible to have a straight flow at times. In certain cases, it is the only source of seepage. The most essential thing to remember in this situation is that you calculate how much water may be stored in your sump pit while still being comfortable. Another difficulty that arises in this situation is when the weather is simply dry during one period and wet during another period of time.

It is more likely that your sump pump pit will be flooded during rainy weather conditions than than during dry weather conditions.

The crucial word in the above explanation is “usually,” since when there is a substantial discrepancy between the conditions of your pump and pit, it is typically time to take more careful note of the situation.

Should a Sump Pump Pit Be Dry?

Yes and no, to be honest. An underground sump pump pit is designed to gather water from any source it may come from. Generally speaking, if you never see any water accumulating in your pit and there is no sign that your pump has ever been turned on, the odds are excellent that you either don’t have the leak that you suspected or that the water is accumulating in a different spot than you suspected. “Should a sump pump pit be dry?” isn’t exactly the best thing to be asking. According to this definition, the proper question is “Should a sump pump always be dry,” and the correct response is no.

  • In this instance, it would be suitable for you to have another look at your prospective seepage problem.
  • For example, some years ago, a guy in the Midwest observed a pool of water in his basement that remained stagnant throughout the day.
  • Strangely, the problem disappeared, and he thought it was due to his sump pump, despite the fact that it appeared to be constantly dry within a short period of time after installing it.
  • After the plumbing was restored, there were no more flooding issues to deal with.
  • It is not necessarily a bad thing for your sump pump pit to have a small amount of water in it, in the ideal case.

As a result, you will know that the pump is operational; second, that there is still a seepage problem that you should continue to monitor; and third, that you are unlikely to require a new sump pump in the foreseeable future.

Sump Pump Always Has Water

In the same way that the answer to the previous question is both excellent and terrible, so is the solution to this question. First and foremost, it is totally typical for a sump pump pit to have some water in it, if not all of the time. In most cases, if there is consistently too much water, there is most likely an issue, especially if you never hear your pump start up. If, on the other hand, there is continuous water in the pit, this indicates that the pit and pump are doing their functions.

  1. This leftover water, which is meant to protect the ink from the non-image sections of printing plates (known as “oldmudder”) from accumulating on the floor of the press room and creating mishaps, was causing accidents.
  2. Following an investigation, it was found that this was okay because the water only collected during press time, which was precisely when the water was accumulating.
  3. Because it involves your degree of comfort as well as practical factors, determining what that level should be is nearly always a question of personal preference.
  4. A plumber is most likely your most reliable source of assistance.


To summarize, if you come away from reading this post with the impression that there is a great deal of subjective material, you would be absolutely accurate. After all, what is beneficial to one individual may not be beneficial to another. Not only do people differ, but so do the circumstances in which they live. Example: A person who lives in a wetter climate may opt for one type of sump pump and pit, while someone who lives in a dryer climate may opt for another type of sump pump and pit. There is just no way to declare that one type of pump and pit is superior to any other in terms of overall performance in general.

If your pump and pit are typically quite dry and only seldom turn on, and you suddenly find yourself in a situation where it is full and turning on more frequently, it is definitely advisable to get it checked out to see what could be causing the change.

Should My Sump Pump Pit Always Have Water Inside It?

As specialists in sump pump installation and maintenance, we regularly receive the following phone call regarding sump pumps: Is there supposed to be water in the pit? If you’ve just had a sump pump installed, or if you’ve recently moved into a property that has a sump pump, you may be unfamiliar with the concept of owning this type of equipment.

But don’t be alarmed. You will learn all you need to know about your sump pump pit and how to tell if your sump pump is having problems in the sections below.

My sump pump pit always has water in it. Is that bad?

It is composed of two parts: the pump itself, and the pit in which it is designed to function, or sump pump pit. If there is usually some water in a sump pump pit, it is totally typical and should not be considered abnormal. It is possible that this water is the product of rain, snowmelt, or seepage from the earth. However, when the water level in your sump pump reaches to a particular level, the float switch on your sump pump should activate. This will cause the pump to switch on and begin to function properly.

My sump pump pit frequently goes dry. Is that bad?

Both yes and no. The sump pump pit should not be left dry on a regular basis, since this is not desirable. A dry sump pump pit can cause the plastic and rubber components of the pump to wear out prematurely, resulting in increased costs. As a result, you’ll need to repair or replace the sump pump considerably sooner than you would have otherwise. On a good side, it’s possible that you don’t have the flooding problem that you thought you did after reading the report. It is possible that the seepage is caused by a pipe or drainage problem, which a plumber may inspect and resolve for you.

What if my sump pump pit is always full of water?

Just as you don’t want a sump pump pit that is continually dry, you also don’t want a sump pump pit that is constantly full of water. This might be an indication that the water table in the area where the pump is located is excessively high. Additionally, there might be an issue with the sump pump itself, such as a clogged or frozen discharge line, which is preventing water from draining. Problems with your home’s plumbing might also result in a sump pump pit that is continually overflowing with liquid.
