Use These Tips to Drain a Water Heater Properly
Most water heater maintenance instructions recommend that you drain a water heater every six to twelve months, depending on how much use it gets. The reason for this is that it will aid in the removal of any sediment or buildup that may have accumulated on the bottom of the water heater tank as a result of the presence of minerals and other particles in the water. As a result of the accumulation, the water heater will have to work harder to heat the water, consuming more energy and increasing its operating costs.
Before You Begin
According to the majority of water heater maintenance instructions, it is recommended that you drain your water heater once every 6 to 12 months. As a result of the presence of minerals and other particles in the water, it is advised that you do this to help remove any sediment or buildup that has accumulated on the bottom of your tank’s bottom. When this accumulation occurs, the water heater must work harder to heat the water, consuming more energy and increasing the overall cost of operating it.

Perform a Quick Flush
- Using a garden hose connected to the drain valve, attempt to clean the water heater tank a little bit while the water pressure is still on before shutting off the water supply. In order to accomplish this, first open the drain valve for a few seconds before closing it again. The pressure will blast away any silt that has become lodged in the valve, allowing the tank to empty more quickly. If a significant amount of sediment is expelled, you may need to repeat the process several times. Make certain that you’ve connected your garden hose to an outdoor place or to a bucket in order to collect the water and sediment that will be emitted from the faucet.
Turn Off the Water Heater
- Turn off the gas to your water heater, or turn off the electricity if you have an electric water heater. Remove water by shutting off the valve on the cold-water pipe above the water heater or the main water supply valve to the home, whichever is most convenient. Test the hot water faucets around the home by turning them on and checking for water to ensure that the pressure has been released. Water may flood out at first, but if the water has been cut off properly, it should rapidly decrease to a trickle and then stop. To relieve pressure in the system, keep a hot water faucet open in the sink closest to your hot water heater.
Open the Drain Valve
- Open the drain valve while holding your garden hose in one hand. Normally, you may complete this task by hand, but you may need to employ your flat-head screwdriver in this instance. Once the valve is opened, water will begin to rush out of the drain, so make sure your hose is either connected to the outside or to a bucket to catch the water. You should switch off the drain valve as soon as the bucket is full so that you may empty it. Repeat the procedure as many times as necessary to completely empty the tank.
Flush the Tank With Water
- Once the tank has been completely drained, you may flush it with a few gallons at a time by turning on the water for a few seconds and then allowing it to drain out again until it is completely empty. As soon as the outflow is free of silt, it will be evident that you have completed the process and may proceed to the following stage.
Refill the Water Heater
- Once the tank has been completely drained, you may flush it with a few gallons at a time by turning on the water for a few seconds and then allowing it to drain out again until the tank is clean. As soon as the outflow is free of silt, it will be evident that you have completed the task and may proceed to the following stage.
Relight the Water Heater
- Re-ignite the water heater’s pilot light, or if it’s an electric heater, re-energize the circuit breaker. You should be able to use hot water after an hour or so.
Check the Drain Valve
- Check for leaks at the spout of your water heater to see if the drain on the heater has completely closed. If the outlet does not completely close, you can stop the leak by placing a threaded hose cap over the hose thread of the outlet. Alternatively, you can replace the valve entirely.

How long has it been since you emptied your hot water heater? Previous PostNext Post We all take hot water for granted, until it is no longer available. A chilly shower serves as a jolting reminder of the significance of regular water heater service. Cleaning and emptying a hot water heater is one of the most important preventative maintenance jobs a homeowner can perform to help extend the life of their device.
In addition to removing sediment buildup, draining your hot water tank can help your water heater operate more effectively, which can result in cost savings for you. An unflushed hot water heater will not last as long and will heat water more slowly if the tank is not flushed once a year.
- Deactivate the water supply valve that feeds into the hot water tank. Inspect the water heater’s drain valve, which is located at the bottom of the unit. Open the same valve you used before. Make sure that the pressure release valve is open. Allow the water to drain completely. If you aren’t utilizing a floor drain, make sure you empty the bucket on a regular basis. Turn on the water supply valve when the tank is completely depleted. Ensure that the water continues to flow through the tank and through the drain valve until it is clear. Close the drain valve as well as the pressure release valve to allow the tank to fill. In the case of an electric water heater, reset the circuit breaker or reconnect the device. To relight the pilot light on a gas water heater, turn on the gas and relight the pilot light.
While this may appear to be a straightforward procedure, there is the possibility of flooding in your basement if you do not proceed with caution. Plastic hot water heater valves, as well as valves that have not been used in a long time, are susceptible to leaking. Continue to keep an eye on the valve after it has been shut in order to verify that it is not malfunctioning. Even a little trickle might quickly escalate into a major issue.

What Would Bob Do? Draining a Water Heater
Image courtesy of shutterstock.com I’ve just finished draining my water heater for the first time since it was installed in 1989.24 years ago today! I stopped after approximately five minutes since the water came out incredibly clear and there was no trace of any silt. Is this a sign that my heater is devoid of any sediment? Whatever sort of storage tank water heater you have, draining your water heater at least once a year is a good practice. Over time, sediment accumulates within the appliance, reducing its energy efficiency and causing blockages in other fixtures throughout the house, including the kitchen sink.
To remove sediment from a water heater, it is necessary to drain it not just for five minutes, but for as long as it takes for the water heater to entirely empty.
STEP 1: Check the pressure-relief valve.
Before you empty a water heater, make sure it has a pressure-relief valve, which is the device that prevents the tank from exploding due to excessive pressure. You must confirm that the valve is operating correctly in order to do so. Turn off the water heater’s electricity supply. (If the unit is powered by electricity, simply shut it down.) If it is a gas-powered heater, turn it to “pilot” mode to conserve energy.) After that, open the cold water supply line valve by pulling the lever on the valve.
Once you’ve opened the valve, listen for air and look for water to confirm that it’s working.
In addition, if you open the pressure-release valve and nothing happens—no hissing air, no pouring water—it is likely that the valve has to be replaced.
STEP 2: Run your drain line.
Examine the pressure-relief valve on a water heater before draining it. This is the device that prevents the tank from exploding due to excessive pressure. You must confirm that the valve is in perfect working order. The water heater’s electricity should be turned off.’ The unit should be turned off if it is powered by electricity (if so). The heater should be switched to “pilot” mode if it runs on gas.) After that, open the cold water supply line by pulling the lever on the valve. For the final step, place a bucket beneath the pressure-relief valve to contain the mess.
You should move to the next phase if you feel one of these symptoms, which indicates that the valve is functioning properly.
When you open the pressure-release valve, nothing happens—no hissing air, no pouring water—which indicates that the valve needs to be replaced. Illustration courtesy of instructables.com.
STEP 3: Flush your tank.
After you’ve opened all of the hot water taps in your home, you’ll want to open the water heater drain valve as well. In the event that you have opted to utilize a pump, this is the moment to turn it on. Allow the tank to completely empty before turning on the water supply (short bursts of water may help to dislodge any sediment buildup). Make sure there isn’t any silt blocking or slowing down your drain valve’s flow by doing the following: Remove the drain valve, in other words, to allow the sediment to leave through a bigger hole.
Keep a number of big buckets on standby to catch any excess water.
STEP 4: Finish up.
Re-start the water supply after the water flowing out of your tank looks to be running clean once more. Next, close the water heater’s drain valve and switch on the cold water supply to the house. It’s also important to remember to restore the pressure-relief valve to its original position. Close all of the hot water taps in your home (which you had previously switched on in Step 3) and, lastly, reconnect the electricity to your water heater, which should now be clear of sediment after you completed Step 3.

Frozen Hose Bib: How to ThawPrevent Major Water Damage
Is it necessary to empty your water heater? Yes. To avoid scaling and silt from collecting inside the tank, you should perform this procedure once a year, or even more frequently if you have hard water. Sediment might have the appearance of sand, yet it is composed of minerals derived from your home’s water supply. As a result, these minerals do not dissolve and instead condense into little particles within your unit. Unfortunately, if left unchecked, this build-up may create substantial concerns, including time and money savings by decreasing the unit’s efficiency and functioning, as well as the possibility of the water heater failing prematurely, leading you to lose time and money.
How to Flush a Water Heater:
- To begin working on your water heater, make sure that all of the electricity to the device has been turned off, including the circuit breaker. Immediately turn off the cold water supply and wait a couple of hours for the heater to cool (this may take many hours). Locate the drain valve on your water heater, which is usually located at the bottom of the tank. It is possible to drain the water from the tank without using the floor drain by using a conventional garden hose and connecting it to the valve. The water will be directed into a bucket. Although many people may simply use gravity to drain water from the device into a bucket, following the manufacturer’s connection instructions is recommended if you wish to pump the water outdoors (which makes disposing the unwanted water easier). In order to avoid damage to your pipes, open one or two hot water taps around the home. Drain the water and look for silt by opening the drain valve. if the water is turbid or cloudy, refill the heater with fresh water and drain it once again Turn the water shut off valve on and off a couple of times to mix up any sediment that has accumulated at the bottom of the tank
- Continue to fill and empty the heater as often as required until the water flows clean. If the unit is in good condition, one flushing is usually sufficient, and you will not need to flush it again for at least one year. It may be necessary to consult with a specialist if there is an excessive quantity of sediment in your water. Once the water flows clear and the unit is completely empty, remove the hose and pump from the unit. Close the drain valve and replenish the tank before turning on the water heater’s power source. Turn on the water heater’s power source. Performance should return to normal, with the exception of a few air pockets that will be expelled via the faucets at the beginning. In most cases, the air will be expelled within a few seconds, and then full water flow will be restored to the system. Close all of the water faucets that you have previously opened.
How to Tell if Your Water Heater Has Sediment Build-Up
There are a number of symptoms that your water heater has a sediment build-up, including the following ones:
- Despite the fact that energy use has not increased, energy costs have grown. The hot water runs out before it should
- When the water heater is operating, it generates a lot of noise. Your hot water appears to be rusted or has a foul odor
- It takes an extremely long time for the hot water to come to temperature
- There is inconsistency and fluctuation in the water temperature.
Draining a water heater is a relatively simple task that most homeowners can complete on their own. However, if the water does not drain or if the heater’s performance issues persist after flushing the unit, a professional will be able to identify other potential problems that may not be apparent to the homeowner.
How to Drain Your Hot Water Tank (And Why You Should!) — Multi Trade Building Services
The capacity of hot water tanks is meant to last for many years, but cleaning them should be included in your normal home maintenance program. Following our step-by-step directions outlined below, this is an easy DIY project that you can complete on your own.
Why should I flush my water tank?
The majority of hot water tanks feature a large holding tank, which guarantees that there is always sufficient of hot water available when it is needed. Nonetheless, because the water is left to stay in the tank on a continuous basis for an extended period of time, naturally occurring minerals in the water, as well as sand and grit discharged from municipal water pipes, can accumulate in the tank’s bottom. The accumulation of silt in your hot water tank may make it more difficult for it to perform its function.
Hot water tanks should have a life lifetime of at least 10-12 years, however failing to remove the sediment from the tank on a regular basis can dramatically shorten that life term.
What about my gas hot water tank?
In addition, sediment can reduce the effectiveness of the burner in a gas water heater. Have you ever experienced cracking and popping noises when your furnace was heating up? This is due to the silt that has accumulated in your tank. Sediment builds up in a gas hot water tank, forming a thick, crusty layer on the surface. This reduces the amount of heat that is transferred from the burner to the water in the tank. This is a waste of energy and, more importantly, of your money! In the long run, this can create corrosion in the tank, which may produce a major problem if your tank begins to leak all over your floor.
Both gas and electric water heaters should be cleaned of sediment every 6 months to once a year, depending on your water supply and the mineral content. This will guarantee that your water heater performs at its best.
Can sediment affect my plumbing pipes or water?
Fortunately, the quick answer is “yes!” The sediment or crusty stuff that collects at the bottom of your tank has the potential to break loose and become caught in the pipes that distribute water throughout your home. This might cause the flow of water via your pipes and faucets to become more difficult to control. It also has the potential to clog the drain valve on your hot water tank, making it hard to drain the tank without a major plumbing repair job.
An important word of advice:
If you haven’t cleansed your hot water tank in a number of years, it may be in your best interests to hire a Licensed Plumber to take care of the job on your behalf. You run the danger of causing leaks to be activated. It’s conceivable that the silt that has been accumulating in the tank for years has developed fractures in the bottom of the vessel. The existing sediment is clogging those cracks, however draining and flushing the hot water tank may be able to remove the sediment that is “sealing” the leaks and allowing them to reopen.
The fact that you hired a Licensed Plumber to complete the operation ensures that if it does leak, you’ll be prepared to deal with it immediately.
Speaking from experience.
The reason I warn you with the word of advise above is that we had exactly that scenario occur with a client of ours and we wanted to share our experience with you. Approximately 7 years ago, I published a simple advice to draining your hot water tank in a newsletter that I had written. After eight years in his house, my client realized that he had never drained the tank and decided that it would be a good idea to do so now that the weather was getting warmer. He diligently followed all of my directions before calling me in a panic because there was water coming out into his basement floor and he needed me to come immediately.
He, on the other hand, had not anticipated such a problem as a result of following my detailed directions.
It was clear that they had been there for a long time, and the sediment itself was preventing the leak from occurring again.
Our customer ended up needing to purchase a new hot water tank, but he ended up saving a significant amount of money over the long run since his new tank was far more energy efficient.
One important first step
The first step is to identify where the drain valve is located on your tank. It has the appearance of a little outside faucet. Before draining your hot water tank, we highly advise that you cut off the gas or electricity to the tank and let the water drop to room temperature before draining it. It will take several hours to complete this task. This is not required in order to drain your tank, however it is recommended as a safety measure.
If you do not want to wait the appropriate amount of time for all of the water in your water heater to cool, just keep in mind that the water that comes out of the drain valve will be extremely hot when it does.
Steps to Draining Your Hot Water Tank
- Finding the drain valve on your tank should be your first order of business. It resembles a little outdoor faucet in terms of size and appearance. The water should be allowed to drop to ambient temperature before being drained, thus we highly advise that the gas or electricity to your hot water tank be shut off. It will take several hours to do this task properly. However, while it is not required to drain your tank, doing so is a good idea for safety reasons. In the event you decide not to wait the necessary amount of time to allow for complete cooling of the water in your water heater, keep in mind that all of the water that comes out of the drain valve will be extremely hot.
What if my tank won’t drain?
If your hot water tank is draining slowly or not at all, open the temperature and pressure relief (TPR) valve on the hot water tank to see if it helps. In the hot water tank, it’s at the top where you’ll find it. A pipe goes from the top of the tank to the bottom of the tank, and it’s normally operated by a lever that may be raised or lowered as needed. Opening the TPR valve may allow water to drain from the tank if there is a possible vacuum inside the tank that has been preventing it from doing so.
The most prudent course of action is to contact a Licensed Plumber in this situation.
To sum things up.
Despite the fact that it is one of the most often used items in your home, the hot water tank is also one of the most ignored. If you follow the methods outlined above, maintaining your hot water tank will be a simple chore. If you prefer that our Licensed Plumbers handle the maintenance on your hot water tank, please contact us at 905-259-3344 to make arrangements.
