How To Replace An Under Sink Water Filter Cartridge

This article serves as a guide to assist homeowners and water filter system users in the process of changing the filter cartridge(s) in their under sink water filtration system.Granted, many people who possess water filtration systems are already familiar with how to complete the process.The reality is that many people either inherit filter systems from prior home owners or are tasked with the obligation of replacing the filters without any previous experience.

If you find yourself in a difficult circumstance, it is always a good idea to brush up on the procedures and processes in order to avoid any difficulties.

Know Your System

Water filter kits are included with instruction manuals that explain how to properly install the equipment as well as how to perform routine maintenance on the system to maintain it functioning at top performance.A thorough understanding of the components, the plumbing involved, and the manner in which the system has been implemented will all help to a good end..Even if the owner’s handbook is not readily available, it is generally a good idea to read through it thoroughly in order to ensure that you are fully informed about what is going to take place.

Alternatively, if the handbook is not available, you may go online and conduct some preliminary research to locate the instructions.
Actually, going online is a smart idea since many websites provide information on how to change the filter cartridges in your system, including tips, tactics, and strategies that other filter system owners have found useful.

No Plumber Required

Removing and re-installing filter cartridges isn’t exactly rocket science, nor does it need the possession of advanced academic degrees to do the task.It does, however, need the use of tools and other materials in order to complete the work.Information on the required equipment and online comments from past owners should be included in the filter replacement instructions, since this will assist to improve the instructions by providing real-world context.

Always keep in mind that certain filtration systems are built overseas, and the people who write up the instructions may not fully understand what it takes to do the job.
Your patience, tenacity, and persistence will pay you in the shape of a fully functional system that is free of leaks and leaking pipes.

Replace Your Under Sink Water Filter Cartridge In 5 Steps

Step 1 – Assemble the Troops

Simply put, replacing under-sink water filter cartridges requires you to step inside the sink cabinet in order to complete the task at hand.Because the work will be done inside due to the inconvenient environment, it is critical to reduce the number of trips made to obtain tools or other essential equipment.Nobody likes to spend too much time banging their skull against a cabinet or squatting up and down, so it is a good idea to have everything you need close at hand and ready to go.

It’s not a bad idea to have an assistant on standby to provide a helping hand if necessary, such as to aid you in reading instructions or handling equipment when you’re squeezed within the cabinet.

Step 2 – Turn the Water Off

Although it may seem apparent, there have been instances where filter system owners have forgotten to turn off the water and have had a nasty surprise when they begin to remove the filter.Before doing any work, turn off the water supply to the area.A tiny valve, which is usually situated on the incoming water line before the filter system, is used to do this in the majority of water filtration systems.

Other systems require you to turn off the water at the faucet valve located right under the sink in the cabinet or, in certain circumstances, the main water supply valve for the entire property must be shut off.

Step 3 – Follow the Directions Twice

Because going through the procedure once helps acquaint the installer with any potential issues or conflicts that may develop once they can assess the situation up close, reading the installation instructions twice is highly recommended.It is important to walk through the procedure in order to avoid catastrophes and to give the installer more confidence in order to achieve the ultimate goal.Prior to performing the changeover, it is recommended that any difficulties with detaching and reconnecting system components be resolved in order to save time, money, and irritation.

Step 4 – Take Your Time

There is a simple reason why you should read the installation instructions twice: going through the procedure once helps the installer become familiar with any potential difficulties or conflicts that may develop once they can assess the situation up close and personal.Avoiding catastrophes and increasing installer confidence as they go toward the end goal are two benefits of going through the process.Prior to performing the move, it is recommended that any difficulties with detaching and reconnecting system components be resolved to save time, money, and aggravation.

Step 5 – Check, Double-check, and Triple-check

When the process is finished and the new filter(s) have been fitted, it is critical to double-check that there have been no errors.As said above, it is sometimes necessary to allow for some time for an issue to manifest itself, therefore it is a good idea to pull out a flashlight and take a quick check every now and again.Water leaks can be difficult to detect and are not always visible immediately after plumbing repair has been completed.

Even the most experienced plumbers understand that it is critical to thoroughly inspect all connections and valves once the water has been switched back on to verify that nothing is leaking.

Snap-in, Screw-in, or Remote Filters

When it comes to replacing replacement filters, different under-sink water filtration systems employ a range of connection approaches.Certain filters, each with its own connection protocol, are used to remove different impurities and must be updated on a periodic basis.At-line filters should be installed in a location that makes it simple to remove and replace the filter.

In circumstances when the exchange of filters is onerous, it is recommended that the system be modified to make it a simpler operation, promoting rather than discouraging the replacement process.
However, while each filtration system has a suggested filter life, each system is unique due to the fact that its use reflects the needs of its users.
Because the use of other goods will not ensure effective filtering results, it is recommended that you always use the designated filters stated by the system manufacturer instead of others.

Stick With It

Many people who possess under-sink filtration systems believe that changing the filters is too complicated or time-consuming.Their reasoning is that they don’t want to deal with the inconvenience, clutter, or annoyance of crawling around beneath their sink to do the task.A significant error, because the value of filtration of water considerably outweighs the short amount of time and work necessary to maintain the water as clean and contaminant-free as is reasonably practicable.

Everyone wants better tasting water that is also better for their health, and an under sink water filtration system may help you achieve that crucial aim.
With a little planning, effort, and dedication, you may find that the water you desire is only a filter change away from you.

coli or heavy metals, might have a bad impact on your health in the long term.
The majority of filters are capable of reducing or completely eliminating lead, zinc, mercury, copper, cadmium, and chlorine.

The finest fluoride water filter can also help to maintain a safe amount of fluoride in the water.
Furthermore, there are other benefits to installing a whole-house water filter that you should consider.
The majority of people are aware of the advantages of this sort of filter, but many are unaware of the significance of renewing it on a regular basis.
The filter, on the other hand, captures impurities that should not be present in the water that you and your family drink.
Once it becomes blocked with filth, the efficiency of the device will diminish.
As a result, it is critical to clean and replace the cartridge in your water filter on a regular basis.

How Often to Change the Water Filter?

Cleaning or replacing your water filter cartridge on a regular basis (every two to six months) is recommended. You should, however, do this procedure as soon as you see that the water’s color has gotten darker or that the water flow has slowed. It will be determined by a number of criteria, including: Before using the filter, you should read the instruction booklet provided by the manufacturer. Always follow the manufacturer’s recommendations for the best time to clean or replace the filter.
Water quality varies based on where you live, which implies that the water may have varying degrees of contaminants depending on where you are in the world. You should also take into account the hardness of your water. Take advantage of the testing strips that come with the filter system and use them to determine the quality of the water before adding filters.
Filtering capacity – Depending on the model, the filtering capacity can range from 265 to 1585 gallons (1000 – 6000 l) or even more.
The number of users – This is a straightforward criterion. If you use your filter more frequently, you should change it on a more regular basis. If there are more than two people living in the house, you may need to replace it once a month. The frequency with which you need replace the filter, on the other hand, will be determined by the sort of gadget you use in your house.
The number of appliances in your home – One of the most important considerations is the amount of units in your home that require filtration. If you use your filter to purify water in a greater number of devices, you should replace it more frequently.
Filter types – There is a suggested duration of use for each kind of filter that you use. Types of filters – After that, you’ll have to make a modification. Let’s have a look.

Whole house water filter

Since it can offer clean water for my family throughout my entire home, I am a proponent of whole-house water filtration systems. For the greatest results, the device should be installed on the main water supply line, from which it will distribute water to all taps. If you change the filter on a regular basis, you will always have clear water available. The frequency with which you should perform it will be determined mostly by the sort of filter you employ. The majority of traditional types require replacement every 2 to 6 months. The well-sediment filters will need to be replaced the most frequently, while the carbon filter will need to be replaced once every 4 to 6 months. If you are still unsure about when it is necessary to replace your filter, you may consult the handbook, customer service agents, or the manufacturer’s website for guidance.
Inquire with a reputable plumber
When any changes in water quality or water pressure are noticed, it should be replaced as soon as possible.

Refrigerator water filter

If your refrigerator contains an icemaker or a water dispenser, it is also equipped with a refrigerator water filter, which removes contaminants from the water it produces.If you have a water softener, you should change it at least twice a year since pollutants in the water may create an unpleasant taste and odor within your unit.Checking the handbook for the cartridge that your refrigerator uses is the most effective approach to prevent making errors.

Under sink water filter

Because of the size of your under sink water filter, you will need to replace it on a regular basis. If you have a new model, you should replace it every six to twelve months, depending on the model. Using some educated guesses, it is recommended that you replace the filter every: This can take up to nine months if the complete family uses it (high water consumption)
twelve months for a couple (medium water consumption)
and fifteen months if the user is a single individual (low water consumption).

Shower filter

When you shower, these filters lower the amount of chlorine, harsh sediment, and heavy metals present in the water you are using.As a result, they will lessen the irritation on your skin’s surface.It is entirely up to you to decide whether you choose to install a shower filter to a showerhead or purchase a showerhead that already has a filter built.

The amount of water you consume will determine how frequently you will need to replace your shower filter.
Every six months, on average, it is recommended that you replace your filter.
In any case, regardless of the time frame necessary, you will almost certainly need to do it once 10,000 gallons (37,854 l) of water has been used.

Essentially, it will be determined mostly by the number of people that live in your family.
Changing the shower filter every 2 to 3 months, for example, is recommended if you take the shower many times a day.
If you take a shower once a day, it is advised that you replace the shower head once every 4 to 5 months.
In any event, the maximum amount of time you should wait before changing it is six months.
The fact that the shower head filter’s shell is transparent is a wonderful feature.
Because of this, you can tell the difference between a fresh filter and one that is in need of replacement.

For example, if you see a greenish or blue tinge to the filter, you will know that it is time to replace it since there has been an excessive amount of chlorine built over time.
The faucet water filter is replaced in a manner identical to that of the faucet water filter.

How to Change an Under Sink Water Filter Step By Step

We recommend maintaining a record of the specifics so that you don’t forget anything.
The procedure is straightforward and will take no more than half an hour of your time to complete, at the most.
Let’s get this party started.

Gathering Tools and Supplies

It’s unlikely that you’ll need to purchase any more tools or supplies. The majority of the items should be easily accessible at your location. Here is a list of the items you will require: Replacement filters
paper towels or a small pail
O-rings
a plastic or metal filter housing wrench
a replacement filter
Confidence

Closing the Water Supply Valve

If you are looking for it, it will be on the curb outside your house or shortly after where the water enters your home.
Furthermore, switch off the valve on the top of the filtered water storage tank to prevent contamination (RO systems only).

Releasing Pressure

It is necessary to bleed out the pressure from your under-sink water filtering equipment after this has been completed.Simply turn on the sink faucet and let a few seconds of water to run through it to do this.The release of water pressure will assist you in opening the filter housings with ease.However, highly compressed housings will be difficult to open and cause you to perspire unnecessarily as a result.

Removing the Filter Housing(s)

Make use of the filter housing wrench and carefully slip it underneath the filter housing.Slide it as far as it will allow you to go.The grooves on the wrench, together with the long handle, provide you with enough leverage to simply twist.Keep in mind that the righty is tight and the lefty is loose.Give the housing a little push to the left, and then use your hand to unscrew and remove it from the base.

Make a point of collecting any spills in a small container or keeping a towel nearby for cleanup.Drain any water that may have collected within the housing, which is most likely the case, into the nearby sink.It is not necessary to open all of the filters at the same time if your filtration system has more than one filter stage.In order to minimize misunderstanding, only one filter should be replaced at a time.

Checking O-Rings

Once you’ve taken the housing apart, you may remove the old filter cartridge and look into the sump for any problems.Pay close attention to whether the O-ring is properly inserted in the groove and whether it is not adhered to the filter head.In the same way, make that it is not damaged, hard, or full of nicks.If required, replace the old one with a new one.Most carbon filters include two O-rings on opposite side of the filter cartridge, which helps to keep the filter cartridge in place.

Always check to see that the bottom O-ring of the filter housing is not trapped within the filter housing while removing it.The most common error most people do is to insert a new cartridge without first removing the old O-ring from the cartridge.A second ring at the bottom of the filter housing prevents the filter housing from sealing correctly, resulting in leaks.

Checking the Old Filter Cartridge(s)

Some individuals simply throw away their outdated filter elements without even taking the time to look at them.On the contrary, it is always a good idea to inspect the cartridge for an excessive buildup of muck before using it again.An in-depth analysis will provide you with an indication of whether you should change your under sink filters sooner the next time.Overclogging your filters too frequently can not only result in a decrease in filtering effectiveness, but you may also be forced to cope with more major damage to your home or business.

Cleaning the Filter Housing(s)

When replacing filters, it is usually a good idea to clean the filter housings before reinstalling them.In wet environments, mold and mildew thrive as a result of the moisture.Because most houses are built of plastic and are essentially soaked in water 24 hours a day, there is a great likelihood that green algae may make its way into the structure.As a result, take advantage of this opportunity to thoroughly clean your under-sink water filter housings, ensuring that mold, bacteria, and other pathogens do not have a chance to thrive.To begin, thoroughly clean the surface with soapy water and a long bottle brush.

After that, let it to dry completely before reinstalling it.

Optional: Sanitizing

The entire unit must be sanitized with household bleach or an NSF-approved sanitizing solution if there are apparent symptoms of green or black growth in any of the filter housings or other components of your under sink filtration system.Prepare a solution of bleach diluted with water and pour it into the filter housings to activate the enzymes.Keep in mind that you are not need to install the cartridges at this time.Replace the housings on the filter head and turn on the water supply valve to complete the process.Allow enough time for the system to fill with water.

Finally, turn on the faucet to ensure that the bleach solution reaches all of the tubing and the dispenser at the same time.Before cutting off the water supply, give it 30 minutes to cool off.Following that, gently remove the housings and pour the bleach solution down the drain.After each rinse with clean water, dry the housings well.

Installing New Filter Cartridge(s)

Install the new under-sink water filter cartridges, ensuring sure that they are properly seated in the grooves at the bottom of the sink cabinet.

Putting Filter Sump(s) Back On

Using your hand, twist the housings of the filter head back into place.Use your housing wrench to tighten it into place after it’s in position.Another typical error is over-tightening the housings, which is a regular occurrence.Not only will this increase the likelihood of hairline cracks in the threads, but it will also make it more difficult to open the filters the next time you use them.

Opening the Water Supply

Turn on the water supply valve that you had previously turned off. Never directly open a valve while the pressure is at its maximum, since this might cause damage to the filter system. Open the water supply gently, from a quarter to halfway, then to full, with a short period of waiting in between each interval.

Checking for Leaks

Check for leaks in the housings as well as all other connections. If you notice any drips, take care of them as soon as possible.

Further Tips & Warnings

Listed here are some of the lesser-known plumbing tips and methods that only experienced plumbers are aware of: When you replace your under-sink water filter, a leak in the system is frequently caused by an O-ring that has moved out of its proper position. Before going on to more intricate solutions, make sure the O-ring is working properly.
Alternatively, if the housing does not screw back on properly, it is possible that you have placed the filter cartridge incorrectly. Remove it and flip it over so that it is on the other side.
If your housing becomes stuck, you may easily open it with a metal wrench or a strap wrench.
Repressurize the empty tank to around 8 psi if you have an under-the-sink reverse osmosis filter system after you change the filters if you have one.

Approximately 1-2 psi of air pressure is lost from the interior of the storage tank every year on average.As a result, it’s always a good idea to pressurize the air.All you need is a typical bicycle pump, a pressure gauge, and a few minutes to get the air pressure back up to normal.You may ask questions regarding how to replace an under-sink water filter cartridge by leaving a comment in the box below.Maria Martino’s biographical information Maria Martino is a part-time content creator who contributes to our site on a regular basis.

Top 5 Types of Drinking Water Filters

Making decisions may be stressful, but sometimes a choice, such as selecting a loaf of bread from the bread aisle, can only lead you so far in the wrong direction.While other instances, such as when selecting a water filter for your house, the selection is crucial, this is not always the case.It’s inconvenient to invest money on a water filter only to discover that the filter fixes an issue that doesn’t exist in their lives.Despite this, when confronted with the plethora of water filtration choices available, it can be overwhelming to choose the ideal one for your house – the one that not only improves the flavor of your water but also removes the greatest amount of impurities.Before selecting a water filter, it is critical to correctly identify the ″issue,″ or in this case, to examine the current quality of the tap water being used.

Tap water differs from area to region, and depending on its source, it may or may not have been treated for a variety of impurities.Do not be alarmed.It is less complicated than you would assume.The following is a summary of the most popular types of water filters now available on the market, to assist you in making an informed decision about which water filters are the most appropriate for your household.It’s vital to remember one thing before getting into the nitty-gritty of picking a water filter: it’s critical to first diagnose the ″issue,″ or in this case, examine the current quality of tap water, before making any decisions on which filter to use.Tap water differs from area to region, and depending on its source, it may or may not have been treated for a variety of impurities.

The Tap Water Database, developed by the Environmental Working Group (EWG), is a useful resource for anybody interested in learning more about the water in their area.
It’s an excellent location to gain a basic awareness of the water quality in the area.
Here is a list of the five most popular types of water filtration systems now available on the market.

Activated Carbon

Chlorine, chloroform, agricultural chemicals, organic compounds, silt, and magnesium may all be removed with this product.Adsorption is the most important concept to grasp when trying to comprehend how activated carbon works.Adsorption, as opposed to absorption, happens when one substance adheres to another while passing through another.Adsorption is distinguished from absorption, which occurs when one material absorbs or absorbs another.Activated charcoal, often known as activated carbon, is made from this substance.

Carbon-rich organic material (such as wood, coal, or coconut shells) is converted into char when it is heated in such a way that it does not burn but instead produces a charring effect on the surface.Once the char has been cleaned, it is transformed into a porous substance that binds to certain poisons and contaminants, allowing them to be removed from the water that is running through the system.This is the most popular form of filter, and it is frequently used in conjunction with other filtration technologies in order to get the most amount of toxin removal possible.Water filtration systems such as Aquasana Whole House Filter Systems, for example, are activated carbon systems that include a salt-free water conditioner, copper-zinc-and-mineral stone, as well as ultraviolet light for optimal filtering.

Ion Exchange

Chlorine, chloroform, agricultural chemicals, organic compounds, silt, and magnesium may all be removed using this method.Adsorption is the most important concept to grasp when trying to comprehend how activated carbon operates.Adsorption happens when one substance adheres to another while passing through another, as opposed to absorption, which occurs when one material absorbs or soaks up another one.Activated charcoal, also known as activated carbon, is made out of this material as its base.In order to produce activated charcoal, an organic material with a high carbon content (such as wood or coal) must be heated in such a way that the substance does not burn but instead results in a layer of charcoal.

Once the char has been processed, it is transformed into a porous substance that binds to certain poisons and contaminants, allowing them to be removed from the water passing through the system.This is the most popular form of filter, and it is frequently used in conjunction with other filtration technologies in order to get the greatest amount of toxin elimination.A good example is the Aquasana Whole House Filter Systems, which are activated carbon filtration systems that include a salt-free water conditioner as well as copper-zinc and mineral stone as well as ultraviolet light for optimal filtering efficiency.

Reverse Osmosis (RO)

It is efficient at removing a large proportion of pollutants, including fluoride, hexavalent chromium, arsenic, nitrates/nitrites, copper, radium, salt, and other noxious substances.Reverse osmosis filters are quite popular for a very good reason – they provide excellent value for money.Reverse osmosis filters are the gold standard for eliminating a high proportion of pollutants from water, including potentially harmful waterborne germs.They are also the most expensive.The filters function by applying pressure to the water as it passes through the reverse osmosis membrane.

On one side of the film, pollutants are retained, whilst fresh water is forced to the opposite side of the film.It is one of the few filters capable of removing water-soluble pollutants such as fluoride and chromium +6 from drinking water.As long as a residence is equipped with a water softener, a RO system will also remove salt from the drinking water.While reverse osmosis systems are becoming increasingly popular, they consume a disproportionate amount of water – often up to four times the amount normally consumed.Additionally, the procedure is sluggish, resulting in a drop in water pressure.It’s for this reason why whole-house reverse osmosis systems are rarely found.

Furthermore, for everyday activities such as flushing toilets, taking showers, and doing dishes, the amount of filtration is not required.
More information on the advantages and disadvantages of RO may be found here.
OptimH2O® Reverse Osmosis + Claryum Filter is a water purification system.

Mechanical

Physical particles and waste stuff may be removed effectively with this method.Mechanical filters are most commonly employed as a pre-filtration approach before other filtration methods.A mechanical filter filters water, and waste material becomes lodged in nylon floss, synthetic foam, or in pads as the water rushes past them.A fish tank filter, for example, would capture plant items such as leftover fish meal and waste but would not capture helpful bacteria that the fish need to survive.

Ultra Violet Filters

It is beneficial in the elimination of germs and viruses.UV filters, which are an environmentally friendly choice, will purify water by utilizing different frequencies of ultraviolet light.The DNA in microbial cells absorbs this ultraviolet radiation, which effectively destroys all bacteria and viruses in the water supply, therefore cleaning it.As previously said, UV filters only eliminate bacteria and viruses from water, thus it is critical to use this filter in conjunction with other types of filters to remove common toxins such as chlorine, lead, and pesticides from water, resulting in clean, drinking water.SHOP UV FILTER SYSTEMS FOR THE WHOLE HOUSE

Cartridge Filter Care

The filtering medium in cartridge types is made of a synthetic spun-bond polyester material that is spun together.When water runs through the medium, the particular architecture of the fibers catches any debris that may otherwise pass through.Because of the bigger debris, the finer particles are filtered out when the pores of the element become covered by it.Cartridges for swimming pools can not filter as finely as diatomaceous earth, which may filter particles as small as 1- to 6-microns in size.They are more effective in the 5- to 20-micron range, whereas sand filters are more effective in the 20- to 40-micron range (after cleaning; however, after half their filter run, they typically can filter in the range of 8- to 15 microns).

Due to the lack of a backwash valve in a cartridge filter system, the hydraulics of the system are rather straightforward.Perhaps more crucially, the waste water created by backwashing cartridge filters does not necessitate the installation of extra piping.Cleaning cartridge filters, on the other hand, is a breeze.Pressure washing the cartridge element in conjunction with the use of a filter cleaner is an effective method of cleaning it.The cartridge elements may simply be removed and soaked in water before being placed back into their respective tanks.

Watch that gauge

As a result, manufacturers have created filters with sufficient surface area (300-600 square feet), so that they only need to be cleaned once or twice every year.However, like with all forms of filter media, you can tell when cartridges need to be serviced by keeping an eye on the tank pressure monitor.The start-up pressure on the tank gauge, which is measured in pounds per square inch, should be checked whenever a filter element has to be replaced (psi).Some manufacturers are now including a simple dial on the pressure gauge to allow you to easily check the pressure levels at any time.It is also possible to draw a line on the face of the gauge at that point using a grease pencil or magic marker, which will serve as a mark for the ″base-line,″ ″beginning,″ or ″starting″ pressure if this option is not available.Now mentally increase the pressure by 8 to 10 psi and put another little note on the gauge to reflect this increase.

In this case, the gap between the two markings represents the ″normal operating pressure″ for that particular cartridge filter system.As long as the filter is operating between those two points, everything is typically in working order.When the pressure gauge reaches a higher reading, it is time to clean.To make things easier, you may just enter the cartridge-filter readings into your own records or route sheet.

If you let the filter sit for an excessive amount of time before cleaning it, you will blind-off pleats and maybe collapse the filter element.As a result, the filter will get damaged and will need to be changed.

Dirt can be a good thing

According to cartridge producers, a somewhat dirty cartridge is actually more efficient than a clean cartridge, despite the fact that this appears to be at odds with its intended use.Why?Because the dirt that collects on filter fibers causes the filter material to form a tighter web than it would otherwise, it is capable of catching finer particles than it would otherwise.At this stage, the dirt that has been caught is essentially performing the same function as diatomaceous earth in a DE filter.That is not to claim that cartridge filters are impervious to the requirement for maintenance.In order to convey the point that a brand-new element is not as good in removing debris from water as a more ″seasoned″ element, the following example is used: Some pool professionals choose to change filter media rather than clean pools with high bather traffic or other situations that make it difficult to maintain good filtration.

It’s a matter of personal preference.Carrying an extra cartridge or two in your truck may prove to be beneficial in an emergency.You’ll be able to replace the customer’s cartridge while also returning the old one to the manufacturer for a more complete cleaning.Note: This paper was written with the assistance of Richard Howell, a former national sales manager at Filbur Manufacturing and current vice president of sales, pool division, for Waterway Plastics, who also contributed to it.

Closing the Water Supply Valve

Don’t undertake filter changes without first cutting off the water supply to your kitchen and, eventually, your entire house to prevent floods.Locate the feed water valve towards the rear of the cabinet and rotate it horizontally to the supply line to complete the installation.If your system does not have a feed water valve that you can turn off, or if the feed water valve is defective or jammed, you should switch off the main water supply.If you are looking for it, it will be on the curb outside your house or shortly after where the water enters your home.Furthermore, switch off the valve on the top of the filtered water storage tank to prevent contamination (RO systems only).

It is necessary to bleed out the pressure from your under-sink water filtering equipment after this has been completed.Simply turn on the sink faucet and let a few seconds of water to run through it to do this.The release of water pressure will assist you in opening the filter housings with ease.However, highly compressed housings will be difficult to open and cause you to perspire unnecessarily as a result.

Removing the Filter Housing(s)

Make use of the filter housing wrench and carefully slip it underneath the filter housing.Slide it as far as it will allow you to go.The grooves on the wrench, together with the long handle, provide you with enough leverage to simply twist.Keep in mind that the righty is tight and the lefty is loose.Give the housing a little push to the left, and then use your hand to unscrew and remove it from the base.Make a point of collecting any spills in a small container or keeping a towel nearby for cleanup.

Drain any water that may have collected within the housing, which is most likely the case, into the nearby sink.It is not necessary to open all of the filters at the same time if your filtration system has more than one filter stage.In order to minimize misunderstanding, only one filter should be replaced at a time.

Checking O-Rings

Once you’ve taken the housing apart, you may remove the old filter cartridge and look into the sump for any problems.Pay close attention to whether the O-ring is properly inserted in the groove and whether it is not adhered to the filter head.In the same way, make that it is not damaged, hard, or full of nicks.If required, replace the old one with a new one.Most carbon filters include two O-rings on opposite side of the filter cartridge, which helps to keep the filter cartridge in place.Always check to see that the bottom O-ring of the filter housing is not trapped within the filter housing while removing it.

The most common error most people do is to insert a new cartridge without first removing the old O-ring from the cartridge.A second ring at the bottom of the filter housing prevents the filter housing from sealing correctly, resulting in leaks.

Checking the Old Filter Cartridge(s)

Some individuals simply throw away their outdated filter elements without even taking the time to look at them.On the contrary, it is always a good idea to inspect the cartridge for an excessive buildup of muck before using it again.An in-depth analysis will provide you with an indication of whether you should change your under sink filters sooner the next time.Overclogging your filters too frequently can not only result in a decrease in filtering effectiveness, but you may also be forced to cope with more major damage to your home or business.

Cleaning the Filter Housing(s)

When replacing filters, it is usually a good idea to clean the filter housings before reinstalling them.In wet environments, mold and mildew thrive as a result of the moisture.Because most houses are built of plastic and are essentially soaked in water 24 hours a day, there is a great likelihood that green algae may make its way into the structure.As a result, take advantage of this opportunity to thoroughly clean your under-sink water filter housings, ensuring that mold, bacteria, and other pathogens do not have a chance to thrive.To begin, thoroughly clean the surface with soapy water and a long bottle brush.After that, let it to dry completely before reinstalling it.

Optional: Sanitizing

The entire unit must be sanitized with household bleach or an NSF-approved sanitizing solution if there are apparent symptoms of green or black growth in any of the filter housings or other components of your under sink filtration system.Prepare a solution of bleach diluted with water and pour it into the filter housings to activate the enzymes.Keep in mind that you are not need to install the cartridges at this time.Replace the housings on the filter head and turn on the water supply valve to complete the process.Allow enough time for the system to fill with water.Finally, turn on the faucet to ensure that the bleach solution reaches all of the tubing and the dispenser at the same time.

Before cutting off the water supply, give it 30 minutes to cool off.Following that, gently remove the housings and pour the bleach solution down the drain.After each rinse with clean water, dry the housings well.

Installing New Filter Cartridge(s)

Install the new under-sink water filter cartridges, ensuring sure that they are properly seated in the grooves at the bottom of the sink cabinet.

Putting Filter Sump(s) Back On

Using your hand, twist the housings of the filter head back into place.Use your housing wrench to tighten it into place after it’s in position.Another typical error is over-tightening the housings, which is a regular occurrence.Not only will this increase the likelihood of hairline cracks in the threads, but it will also make it more difficult to open the filters the next time you use them.

Opening the Water Supply

Checking for Leaks

Check for leaks in the housings as well as all other connections. If you notice any drips, take care of them as soon as possible.

Further Tips & Warnings

Listed here are some of the lesser-known plumbing tips and methods that only experienced plumbers are aware of: When you replace your under-sink water filter, a leak in the system is frequently caused by an O-ring that has moved out of its proper position. Before going on to more intricate solutions, make sure the O-ring is working properly.
Alternatively, if the housing does not screw back on properly, it is possible that you have placed the filter cartridge incorrectly. Remove it and flip it over so that it is on the other side.
If your housing becomes stuck, you may easily open it with a metal wrench or a strap wrench.
Repressurize the empty tank to around 8 psi if you have an under-the-sink reverse osmosis filter system after you change the filters if you have one.

Approximately 1-2 psi of air pressure is lost from the interior of the storage tank every year on average.As a result, it’s always a good idea to pressurize the air.All you need is a typical bicycle pump, a pressure gauge, and a few minutes to get the air pressure back up to normal.You may ask questions regarding how to replace an under-sink water filter cartridge by leaving a comment in the box below.Maria Martino’s biographical information Maria Martino is a part-time content creator who contributes to our site on a regular basis.The University of Chicago awarded her a Bachelor of Arts in Multimedia Journalism.
