How to Drain & Flush a Hot Water Tank | Repair and Replace

How do I remove sediment from my hot water tank? In this episode of Repair and Replace, Vance shows how to do a deep flush of a water heater. Also you'll learn what to do if the tank isn't draining properly. Without regular tank flushes, sediment can accumulate on the bottom of the tank and can act as an insulator, reducing the efficiency of the water heater.

*NOTE* At 2:47 the hot water handle is opened. This is an error and the cold water handle should have been opened instead. When filming these videos we often film multiple takes at different times and the pieces are edited together afterwards. During the backflushing shot we did what visually looked best on camera (moving the closest handle) while not realizing it was the wrong handle (which not would result in any water flowing). This wasn't noticed until after filming was complete.

[@UncleFjester]

So take down the video and reshoot it!

[@schutzhund3933]

I was wondering!

[@AmreSupply]

@@UncleFjester Thanks for watching. Removing the video would mean it would lose all interactions, comments, and views and that is something you don't get back. For a reshoot, the error would have to more significant than the difference between the hot and cold handles. This is something that someone can figure out and is why we put this note.

[@davedavenport8176]

Yep I saw that was going to comment as if you are back flushing and of course have the water to the tank off then use the hot water to supply water back words well oops 😬 not going to work. It would be a good idea to make sure a faucet is open on the hot side to allow the water into the tank.

[@docbrown6550]

I and my brother that lives next door to me built our homes at the same time. We put in the same identical hot water heaters, ( Electric & the same Brand ) I had to replace mine after 15 years, my brothers hot water tank is still going strong seven years later. The only difference in our hot water tanks is I flushed mine every year, my brother has never flushed his. The plumber that helped me change it asked me on the phone how much have I flushed it out through the years, I asked him why was that a factor, he explained that water heaters that have been changed by him the majority were changed had been flushed out on a regular basis. I stopped flushing mine. Both my brother and I are on the same well water also, sharing a deep 600 ft deep well.

Yes, this is the correct method. I change my electric heaters to a ball valve, full port. I have had to run wire or a 3/8 " water line inside to agitate the sediment. Also for the thrifty, turn off the water heater and have a bath before the flush.

What about my video

[@ErikS308]

The back flush with a washing machine advice may have just saved me over $650. My hot water was slow and had low pressure and about a year ago I drained my 16 year old electric HWH. Well that drain was iffy and the low pressure issues came back. The drain valve was clogged and nothing could flow. By putting a washing machine line on a hose, opening a valve in the house and backflushing the tank I was able to get it flowing and flushed. Crud came out and my hot water pressure is like new! Maybe I can get another 5 years out of my HWH now. Yay!! Remember if you do it to open a valve in the home to allow the back flowing water a place to go and to then drain your tank. It took doing it three times on my old HWH.

[@AmreSupply]

Our hot water heater [HWH] had not been flushed for more years than I want to admit. Following the directions in this video I got next to no where. Blowing cold water in from the washing machine cold water point 6 times into the HWH didn’t do the trick. So I shut off the HWH drain valve and let my drain hose [laid outside the house] drain until empty. Then I stood on a ladder and using a funnel that fit inside the hose shut off valve on the end of it - I filled the hose with white vinegar. When the hose was full, I shut off the valve on the end of the hose and reconnected it to the cold water hose for the washing machine. I then turned on the cold water to pressurize that hose, opened the valve at the end of the drain hose and then the drain valve on the HWH. In this sashion I blew about a pint of vinegar into the HWH. I did this twice and now the sediment has been disolved enough that water is flowing strongly out of the drain hose.

[@AmreSupply]

Thanks for sharing your experience! We try to give enough information to point people in the right direction but there are always cases that are more difficult than others. It's not surprising that after so many years without any flush that it took vinegar to help dissolve the sediment. Cheers.

[@theopinions47]

I’m glad you caught that because I was about to correct you myself. That would be problematic. I generally fill up the tank and listen to know that it’s filled. Than I plugged the hot water heater on and let it heat up some for about 15 to 20 minutes than I turn on the faucets. Turning on the faucets in this fashion not only gets the air out but the sediment in the pipes which is why you usually will see brown water for about 50 seconds or so. If you turn on the water before filling the tank you could damage the hot water heater.

If you WH is old like mine, after the flush I suggest that you refill the tank slowly. My first time I did not - blasted the water back in with the valve wide open and ended up with a lot of sediment suspended in the tank which = tan colored water. I redid the flush and then Very Slowly filled the tank, progressively opening the valve more as the tank filled but never opening all the way. Made a huge difference. Nice clear water!!

If it stops draining and still not empty , just lift the hose up to your height and shake a few times then blow like inflating a balloon if necessary ; OR shut off boiler drain and open water supply, that will move that big chunk of sediment out of the way stirring the bottom of the tank. I usually just connect the hose and open boiler drain, the chunks might break loose with the pressure, and you can hear them rattling in the bottom then combine on and off of water supply and boiler drain till you get good free flow and no more sediment, . Believe me , I'm a plumber and it's been times I had to remove lower heating element to be able to push sediment out, never been flushed in ten, 15 or 20 years.

Thanks for this very clear instruction. Question... We have an American ProLine 40 gallon tank. It's now about 7 years old. The makes a "banging" noise whenever we run hot water for more than a minute or so. There are no problems, just the noise. The banging never occurred in our old water heater (also a 40 gallon) and only started about 3-4 years into use on the current water heater. We don't have an expansion tank and never have. We suspect that an expansion tank may solve the noise problem, but will probably not bother unless the banging is going to make the water heater fail sooner than without adding one. By the way we do have a water softener and the water entering the tank is softened. Thoughts? Should we be concerned and do something about the water heater banging noise?

[@AmreSupply]

Thanks for watching. If the banging happens when you stop the water flow, then that would be water hammer. In your case it seems like the noise happens after water runs for a minute, so it is likely air bubbles rising to the surface and pushing sediment around the inside of the tank. Doing a flush can help reduce the sediment and might reduce the noise.

Question and sorry if this is a dumb question. My water valve is corroded to the point that I can’t turn it off. Could I still do the flush with the cold water running and still follow the rest of your instructions. Also let’s say I can’t shut off the main line water to the house either.

[@AmreSupply]

Thanks for watching, and that is a perfectly valid question. If there's no way for you to shut off the incoming water supply then its likely that your tank would drain slower than the refill rate from your cold water supply line. Drain valves do not have large openings and often there is debris that will slow down the draining. So if your drain valve drains at 0.5 - 1 gallons per minute and your cold water supply line fills at 1.5+ gallons per minute then you wouldn't be able to drain the tank completely. Still you'd be cycling some of the water and some of the debris might flush out during that process. So you could try draining some water and monitor what comes out of the hose to see if any sediment is being removed.

[@tonylittle8634]

I’ve seen 30-50 year old tank water heaters. The common ground of all was filtered water. They all had 5 micron filtration prior to water entering the tank. The amount of times the tank fires up is another factor. Pressure is a huge factor. Last common factor is bonding and ground.

For back flush do i need to close the drain valve? Or does that stay open during back flush

[@AmreSupply]

Thanks for watching. When flushing the tank, it can be most helpful to drain the tank fully and then turn on the cold water supply to spay water onto the sediment at the bottom of the tank. A back flush can be done when the water isn't draining, as a back flush will help clear any sediment that blocked the drain valve. For a back flush you'll need the drain valve open.

I was just wondering how if you open up a faucet in the water line how will that leave pressure in the system

[@AmreSupply]

Hi Arlen, thank you for watching. Opening up a hot water faucet will allow air to escape which will reduce the pressure when the tank is drained. Without it, the system is air locked, and the pressure the air in the system will prevent the water from draining. Its the same principle as using a straw. If you pull water into the straw and then put your thumb over the top, the water will stay in the straw. When you release your thumb, the water will fall out of the straw.

What do you suggest if even the back flush fails to clear the clog? I've tried opening the drain valve with the water still going and that's only getting bits and pieces out

[@AmreSupply]

Thanks for watching. People have used a variety of creative solutions to clear a blocked drain. You could use a wire to help push the sediment clear of the drain. Just make sure that you do not damage the rubber stopper or the drain valve might leak afterwards. Other people have used compressed air to "burp" the system. Others have rigged up a shop vac to try to use suction to clear the blockage. These might take more creativity to set up.

Can a broken outside spigot cause low water pressure in a house, My spigot does have a crack in it. I have no leaks in my home, water meter is remaining normal. But I have lost water pressure in my whole mobile home both hot and cold water. I replaced all faucets about a year ago and hot water tank as well.

Question here please. My tank has 8 year warranty, I'm on the 9th. Ive never drained it until now. I agitated the bottom many times and finally got the tank to run clear. Problem is inside hot water is still off colour. I live in Vancouver, BC for location. Evety plumber says I need a new tank. Is there more I can do?

[@AmreSupply]

Thanks for watching. There might have been some very fine sediment that is now floating in the tank. After a shower or two that will likely disperse. If the tank is still heating effectively you might not need a new one. Has the water started to run clear now?

[@Adamrich1987]

So I would recommend replacing any plastic valves with a brass valve. I have always attached the hose and open the drain. Valve first before turning off supply to heater. After you drain the heater adding a full port hose bib will speed up draining and cleaning in the future

[@AmreSupply]

Thanks for watching. You are right that brass valves are the way to go. In this video we show how to replace the drain valve and also outline the 3/4" full port ball valve as an option.

[@JKydd]

My GE water heater is now 10 years old. The water heater was already in the house when i bought it and was never serviced by the previous owner. The hot water has far too little pressure at all the taps. But the cold water is under full pressure. I thought flushing the tank might help, but the pressure is still low. What else could be the problem?

[@AmreSupply]

Thanks for watching. Some hot water systems are fitted with filters, if there is a filter then a build up of sediment can restrict the flow for the hot water. It can also be an issue with the pipes themselves. Sometimes corrosion can build up, but this will be effected by age of the home, water quality / composition, and the type of the pipes. This is harder to diagnose so it can be helpful to call a plumber in this case.

[@barneyrubble4827]

Sometimes the relief valve may not close properly after, I've had several that slow dripped after opening as you suggested, all on older units requiring replacing. I don't use them that way any more.

[@MoSportsUSA]

Good video and explanation but I have a suggestion. Replace the tank drain gate valve with a ball valve. You should precious few if any issues with the drain valve clogging, essentially eliminating the need for the back-flushing operation. Also, any dirt, grit, sediment, etc. between the gate valve internal seat and washer when attempting shutoff will otherwise ruin the valve seat and almost guarantee leakage from then on. Just my two sense (cents, lol) from having rental properties.

[@AmreSupply]

Thanks for watching! That is a great tip as full port ball valves are rock solid. This is something that we mention in the drain valve replacement video: kzbin.info/www/bejne/pHimlp2DqLCBjpY

Thanks for watching. It could be helpful to clear or replace the aerator as well you could, turn off the shutoff valve, disconnect the faucet supply lines and see if the how water flows once you open the shutoff valves. If the hot water flows when the faucet supply line is disconnected. then the blockage is in the faucet.

If we have a sediment issue should we expect to see the sediment flush out of the hose as we drain the tank?

[@AmreSupply]

Thanks for watching. Depending on the size of the sediment you should see some.

[@smoke05s]

A couple of observations when you backflush, shouldn't you use cold water? The hot water will be off at the haterheater. Also shouldn't you use a different faucet than you are using to vent the hot side?

[@AmreSupply]

Thank you for watching. You have a good eye. This has been pointed out in previous comments but unfortunately its not something that we can update. When filming these videos we often film multiple takes at different times / locations, and the pieces are edited together afterwards. During the backflushing shot we did what visually looked best on camera (moving the closest handle) while not realizing it was the wrong handle (which not would result in any water flowing).

[@ashotmm]

I don't understand why in the video the back flush is done by opening a HOT water faucet. I would assume that one should open a COLD water faucet, since there shouldn't be any pressure or water in the hot water pipe coming to the faucet - the water supply to the tank is cut off and the tank feeds the hot water pipe feeding the faucet. Am I missing something?

[@AmreSupply]

Thank you for watching! You have a good eye and that is one error that made it into the final video. When we filmed that shot we naturally showed did it in a way so the arm wouldn't block the shot. In this case what looked visually good while filming, created a continuity error that went unnoticed until after filming is complete. Unfortunately we can't change that shot now without deleting the video.

So I should turn on my cold water, not hot water for the faucet?

[@boblauer8810]

@@junkim5331 If you need to do a back flush, yes. A back flush with hot water won't work because you won't have any hot water to use, your tank will be empty.

Got it! Opened the pressure value and it started draining!

[@dickeymoore3662]

So when draining do I leave the faucet open and close the faucet when filling the tank back up?

[@AmreSupply]

Thank you for watching. The point of opening the facuet is to let the move freely in or out. You'll need to keep the hot water faucet open when draining the tank, and while filling the tank back up.

As a plumber of over 20 years, the best way to get rid of sediment is to cut both copper lines drop that concrete filled water heater and install a new one. I have seen too much sediment run through the house clogging up all the fixtures.

[@AmreSupply]

Hi Vinny thanks for sharing your experience. What do you think about regular or yearly flushing as a way to prevent a buildup of sediment?

[@vinnygoombatts1458]

@@AmreSupply I tell my customers if you start from the time the water heater is new you should be okay but if you go back in after a water has been sitting for even only 2 years you run the chance of distributing that lime and scale all over the house

[@SpookyTooth303]

Great video! How often is it needed to do this?

[@AmreSupply]

Thanks for watching. Some people do yearly flushes and others do not flush for years. It depends on how hard of water there is in your area. You can do a flush and check and see how much sediment comes out. Also without a full port drain valve, less sediment is removed as the pre-installed valves have a smaller diameter. With a lot of flushing there is a chance that the drain valve might not close properly so that is another factor to consider. The difference is shown here: kzbin.infoC3-eTMsbO40

[@chasemist3649]

Thank you for the wonderful video,. I am looking into replacing my supply lines with flexible lines... Should I worry about galvanic corrosion? Seems like the materials would clash. Would liquid teflon product suffice or ? Thank you for the help

[@AmreSupply]

Thanks for watching, we're just happy to help. What you'll want to use is a dielectric nipple which will help prevent galvanic corrosion. Some regions the plumbing code will actually require a dielectric nipple to be used so it's best to check the codes for your region.

When u put shot of cold water again to move the setiment around u need to turn all water supply back right ?...just trying to follow this to a T

Thanks for watching. To blast cold water into the tank you just need to open the cold water supply.

[@jasonsoucek7495]

Is there a way to get the bigger chunks of settlement out of the tank?

[@AmreSupply]

Thanks for watching. That is a good question. Some people have found it helpful to install a 3/4" full port ball valve. This is covered in this video here: kzbin.info/www/bejne/pHimlp2DqLCBjpY

[@SirYoinksalot]

Thanks for the video but I do have a question, my electric hot water tank is about 3 years old and i've noticed the hot water doesn't quite last as long as usual but still is really hot. When I drained (after a shower) the water draining was not hot at all. Barley even warm. I know you mentioned it would be hot. Any ideas?

[@AmreSupply]

Thanks for watching. In addition to sediment or a coating of minerals, there are a couple things could be causing the water to not heat up enough. One of the electric heating elements might be faulty. This can be tested for continuity just like a stove element: kzbin.info/www/bejne/qJ23ZGSkqa6bmKs There could also be an issue with one of the thermostats which controls power to the element itself.

[@SirYoinksalot]

@@AmreSupply I do mean while I was draining it. I checked the continuity and got around 18.2 ohms for each. I also noticed the thermostat was set almost maximum, so I lowered it to the recommended setting. I've been flushing it for about 10 hours now and I'm still getting quite a bit of sediments, but I'm gonna need hot water soon! I'm guessing they'll always be a bit of sentiment I'm just not sure when I should just let it go

[@AmreSupply]

@@SirYoinksalot Thanks for the update. When the water starts looking less full of sediment, then that might be a good time to stop draining if time is a factor. If the water heater still isn't heating up properly, then it is possible that your have hard water, so the elements could be coated with minerals, which will act as an insulator. This scale can be cleaned off of the elements if needed but it would be easiest by removing the elements. We don't have a specific video showing how to do this however there are some good ones if you do a search.

[@j2jcox]

If I have already cut off the water to the hot water heater, and I am back-flushing, wouldn't I want to turn on the cold water, not the hot, so I'd get more pressure for the backflush?

Can you flush it with the water on? I have a gas water heater but water main is outside

[@AmreSupply]

Thanks for watching. To flush the tank you can drain and refill it all at the same time, but it can be helpful to drain the tank completely and do a deep flush.

[@JM-gz1ej]

I tried to drain my 3 year old water heater. However, after an hour the draining from the drain valve would not stop. The t draining from the pressure release valve wound not stop either. Nor did the draining from one of the open hot water faucets.. Seems to me the cold water was somehow back filling into the water heater through the water heater's hot water OUTLET.. Is it possible and how to fix this problem ? Yes, I did closed the cold water inlet to the water heater when doing the draining.

[@AmreSupply]

Hi there thank you for watching. Even though it is not ideal, it is possible for the hot and cold lines to be connected after the hot water tank. Sometimes there are mixing valves that blend the hot and cold lines and other times the lines are connected somewhere else. Its hard to know how things are setup inside your walls as you can't see it. You should have a main water valve that can be shut off. This will stop all water from flowing in your home. You'll still have some water which is gravity fed that will continue to drain until the lines empty, but that should let you drain your tank.

[@JM-gz1ej]

@@AmreSupply Thanks for the suggestions, I will use the main shutoff valve then.

During the process of refilling the tank is there some sort of mechanism that keeps the unit from overflowing? My cold water valve on the water heater is in the on position, so i imagine when the unit refills it'll know at some point when to cease incoming water into the tank

[@AmreSupply]

Thanks for watching. When refilling the tank, have the hot water faucet open in the highest point of your home. The tank will fill until water will run through the hot supply pipes to the faucet. You'll notice bursts of air and water, and when the air stops "burping" then you'll know the tank is full and the hot water line is completely full of water. At that point shut off the hot water faucet, and the system will be good to go.

I ran the water from the flush hose thru a cone shaped coffee filter to see what came out jut make sure you tie wrap the filter on the hose or run the water discharge at a slow rate.

If you put the Pilot light in the “pilot” position when starting the process, why did you have to relight the pilot at the end? Or was that just a filming error?

[@AmreSupply]

Thanks for watching. In the video the gas was shut off and the temperature was set to the "pilot setting" which means it is the lowest setting. At this point the pilot flame and burner are complete disconnected from the gas while the tank is being drained.
