Should You Drain Your Water Heater?


I've read a lot of water heater installation manuals, and they all give the same advice on water heater maintenance, but most people don't do any type of maintenance on their water heaters, period.  Today I'm going to go over the routine maintenance that water heater manufacturers recommend, and I'll throw in my two cents.  My take on water heater maintenance should be much more interesting than reading the installation manual.

Drain Flush the water heater

Every month (yes, every month) you're supposed to flush some water out of the bottom of your tank.  There's a drain valve at the bottom of the water heater tank that can be opened to allow water to drain out.   You don't need to literally drain the water out of the water heater, just open the valve and let some water come out; Rheem says a few quarts is fine.

Water Heater DrainIf you want to really flush out the bottom of the water heater tank, you could attach a garden hose and let a bunch of water flow through.  This water is constantly being replaced by the cold water coming in to the water heater, so you don't even need to have a floor drain close by if you have a long enough garden hose.

If the drain valve leaks when you're done, don't worry.  The cheap, easy, and effective repair is to screw a garden hose cap on to the end of the drain valve.  This is a perfectly safe and perfectly acceptable repair.

The reason for flushing the water heater is to help prevent the accumulation of sediment on the bottom of the tank.  As sediment collects in the bottom of the water heater tank over the years, it will begin to surround and insulate the thermostat, which can lead to the water heater running for longer and longer periods of time, which will decrease the life of the water heater and lead to eratic water temperatures.  I'm pretty sure this is why most water heater manufacturers don't actually publish the water temperature on their control valves.

Water Heater Maintenance ChartSo there's the what and the why... and now my two cents.  I don't drain my own water heater.  It seems like a pain in the butt, and I'm not convinced that doing this will actually help to extend the life of my water heater.  I know it's anecdotal evidence, but just last year I came across a used water heater sitting out in someone's garage for disposal while doing a home inspection in Champlin.  The water heater was installed in 1998 and failed approximately 12 years later.  For the record, water heaters typically come with 6, 9, or 12 year warranties.  What made this so juicy was that there was a chart on the water heater that the owner had diligently filled out every time he drained the water heater... but the water heater still failed after 12 years.  Even though the owner hadn't drained the water heater every month I would have thought this would have helped out at least a little more.

Just for this blog, I hooked up a garden hose to the drain valve on my water heater and flushed some water out.  After about three seconds, the valve itself started leaking extremely hot water out all over me.  I quickly closed the valve and decided not to flush the water heater again.

If you have a new water heater and you're a diligent homeowner, go ahead and flush your tank every month.  If you have a water heater that's several years old and has never been flushed, I've heard it's better to just leave it alone.

Test the pressure relief valve

Every year, the temperature and pressure relief valve is supposed to be opened to allow several gallons of water to drain out.  Doing this will help to clear out sediment accumulation, and will let you know that the valve still operates freely.

Relief Valve

The problem with this test is that the valve may not close properly after it gets opened.  The older the water heater, the greater potential you have for a leaking valve.  If the valve leaks after this test, it can be replaced.  Temperature and pressure relief valves sell for about $10 - $15, and they're fairly easy to replace.

Check the Anode Rod

Every year, the sacrificial anode rod is supposed to be checked for deterioration and replaced if neccessary.   The purpose of the anode rod is to save the rest of the water heater from destruction by sacrificing itself.  Hey, maybe they should call it a Jesus rod ;).  I don't remember much from chemistry, but I found this text at by doing a quick google search:

Cathodic protection is a scheme in which a piece of reactive metal, typically magnesium, is connected to the steel to form an electrochemical cell. Magnesium ions (Mg2+) form more easily than iron ions and enough electrons are given up by the magnesium atoms as they become positive ions to completely dominate the hydroxide ion formation process. With nowhere for their electrons to go, the iron atoms can't become iron ions and rusting can't proceed. As long as the magnesium metal, often called the "sacrificial anode", remains intact and connected to the steel, the steel won't rust significantly.

Wonderful.  I don't quite follow, but the bottom line is that once the anode rod is badly deteriorated, the rest of the water heater will follow.  Replacing the anode rod when needed is supposed to go a long way toward extending the life of the water heater.

Anode RodTo check the anode rod, you'll need to start by turning off the water supply to the water heater, and draining a few inches of water out of the tank.   Now you just need to locate the thing on the top of the water heater that looks like a hex head plug - see the photo at right; that's the top of the anode rod.  Get a 1 1/16" socket wrench (yes, this is a standard size), unscrew the anode rod, and pull it out of the water heater to inspect it.   Once there is more than six inches of core showing at the anode rod, it's time to replace it.

There are four problems you might run in to if you want to check on / replace your anode rod:

  1. Most homeowners in Minneapolis and Saint Paul don't have enough ceiling height in the basement to pull the anode rod out.  If that's the case, they'd actually need to completely drain and un-install the water heater and lay it on it's side to check on the anode rod.
  2. Most homeowners don't own a 1-1/16" socket wrench.
  3. It will probably require an impact wrench to get this thing out.  I tried getting mine out, but it's in there so tight that the water heater actually started to turn, and I didn't have a second person to help me hold the water heater steady.  If you want to see just how tough it is, check out this video - changing a water heater anode rod.
  4. Water heater anode rods aren't readily available at local home improvement stores - the Menards and Home Depot by my house don't sell them, but the Hardware Hank in Maple Grove does.  They had two in stock - one long one, and one short one.

Sorry to be cynical, but checking on and replacing an anode rod is too difficult.  When the manufacturers make it just about impossible to do this step that's supposed to dramatically increase the life of your appliance... of course nodody is going to do it.  What incentive does the manufacturer have in making this step easy?

By the way, if you do happen to replace your anode rod, I've heard you're supposed to save the old magnesium rod for Independance Day.  That's just what I've heard.  Good times.

Good Morning Reuben. Your right. Not sure I have ever actually heard of anyone maintaining their water heater. lol

Posted by Randy Ostrander, Real Estate Broker, Serving Big Rapids and West Central MI (Lake and Lodge Realty LLC ) over 7 years ago

Great advice, although you're right few people ever do it.  Similar filter and cleaning needed on tankless systems.  And again few people do what's needed.  Nice post.

Randy - I rarely hear about it.  Every once in a while I'll hear from someone who swears by draining their water heater every month, but I ain't buyin' it.

Jon - thanks.  I haven't read any maintenance manuals for tankless systems yet...  I don't see nearly as many of those.  I'll have to brush up on that.

Wallace - twenty years is fantastic!  You can't ask for much more.  Well, you can ask, but you probably won't get it.

Ann - me too.  I've never done any of these steps up until writing this blog.

I didn't know until last month my heater has a filter on the bottom.  It's plastic and I'm to clean it every month or two.  However when they installed it they failed to tell me interesting how they charged me for the service call and told me like a afterthought

Posted by James Dray, Exceptional Agents, Outstanding Results (Fathom Realty AR LLC) over 7 years ago

I just suggested you my friend.

In my blog the other day I suggested that manufacturers want us to drain it every year, while plumbers say that the mechanisms are plastic and easy to break! I asked if that easiness might be intentional?

Yes, I'm a jaded old man...

I wouldn't recommend home owners to change their HWT maintenance habits unless they are having problems. Around here the water quality is very good and people rarely touch the tanks at all. They are in service for their full predicted  lifespan and longer in many cases.

Hi Reuben ~ Everytime the water heater is serviced for some reason, this suggestion always comes up and I always promise to do it and then I don't. Thanks again for the reminder. Maybe I need to calendar this and then it won't slip through.

Coming up on 14 years, I'm not to going to start flushing my water heater now.  I'll just wait to replace it and hopefully that won't happen on a freezing cold, winter morning with only cold water comes out of the shower head!  :)

Posted by Dan Weis, (Comey & Shepherd Realtors) over 7 years ago

RUeben ~ What great information.  I thought having it flushed by my semi-annual plumbing inspection was a good thing.  First I've heard about a monthly flush.  I guess you never can have too much information.  Thanks for the post.

Posted by Ken Speer (Alpha Global Associates) over 7 years ago

Last year I drained my water heater.

Done it several times in the past.

But last year, apparently I drained before I shut power to unit off and burned out my 2 heating elements.

Thought at first I was going to have to replace entire unit, and to have installed was looking at around $750 !

But, one of my contractors said I should replace the elements, not the entire heater.

I responded that I didn't have the knowwithall to do such a huge, complicated project!

He said it was actually fairly easy. He recommended I contact the manufacturer, and then go on line and watch videos on how to Do It Myself!

Ahhhhh, technology!

I did just that. And, armed with my new found knowledge and confidence, went to Lowes, bought 2 elements, and installed them myself--cost = $75

The one thing I DID do that I thought was ingenious, was to take a picture of each thermostat gizmo.  That way there, when it came time to hook everything back up, I had a referrence to go to.  Boy, did THAT save my hide!

The water heaters in Houston/Katy are mainly in the attic and let me tell you working with these devices in an attic is no fun. I tried once to do the water hose trick and I had a total mess. Never agin that is for sure. thanks for the blog..

True Reuben, I drain about 1-2 gallons out of ours every 2-3 weeks. We are on well water, and wells around here have lots of iron and manganese in them. What comes out of ours is dark and think green and black sediment that looks like a mix of oil and antifreeze. And we use this same water to cook, shower, drink, etc. I'll try to remember to take and post a pic next time I drain some out.

Great summary and commentary.  I certainly don't drain it every month.  Once a year during the summer, if I remember, is the usual maintenance.

Reuben -- I have never flushed or had my water heater flushed.  It's 12 years old. I am keeping this VERY informative post for reference, but I think I will just leave well enough alone.  I am thinking of getting a new one anyway.  Fingers crossed until I do. Thanks!

Reuben, after losing a water tank on Christmas Day many, many years ago, I'll let it flow until it runs clear, usually two or three times a year.  I've never had an anode rod fully sacrifice itself so that doesn't concern me too much.  If I see rust around the bottom of a tank I immediately become suspect.  Great post that literally hit home!

This is funny. I have drained(flushed) my water heater exactly once. I will never do it again. Painful. I also have seen water heaters that have never been touched that are working fine well past the lifetime.

Thanks for the comments everyone!

Judy - thanks for the suggestion.

James - I wish I knew what this filter looked like.  I don't think I've ever seen that before.

Jay - yes, those plastic drains are definitely easy to break.  I was just glad that tightening my drain valve got the water to stop spraying all over the place.  Thanks for suggesting.

Liz and Bill - you meant Reuben, right?  :)

Robert - I gotta agree with you.  This was the first time I've ever done any maintenance on my water heater.  Ever.

Ritu - see my comment to Liz and Bill above.

Chris - that includes me.

Sandi - I really wouldn't worry about it much.

Dan - after 14 years of not draining your water heater, I think that draining it now would probably only do harm.  Leave it alone.

Ken - you have semi-annual plumbing inspections?  Wow, good for you.  I was also surprised to see that the manufacturers recommended doing this monthly.



Posted by Reuben Saltzman, Delivering the Unbiased Truth. (Structure Tech Home Inspections) over 7 years ago

Fulton - way to go!  Taking a photo was a great idea.  From now on, just remember that you only need to flush your water heater tank, not drain it.

Robert - I think I've seen one water heater in an attic, ever.  That just seems so wrong to me...

Jeff - ewwww.  Yes, please remember to post a pic.

Mike - agreed.

Rob - please do, thanks!

Mel & Gretchen - if you flush your water heater once a year, you're doing better than just about everyone else.

Barbara - My take on water heater replacement is "if it ain't broke, don't fix it."

Kevin - so you've actually checked on your anode rod?  Good for you!

Donald - ditto :)

Chris - yes, and the people that do follow these guidelines don't seem to have any better luck sometimes.

Posted by Reuben Saltzman, Delivering the Unbiased Truth. (Structure Tech Home Inspections) over 7 years ago

James - great blog (ha ha)!  Please explain to me how you have never owned a water heater.  I can't figure that one out.  

Renee - water heaters have water that comes in at the bottom and leaves at the top.  The idea with flushing your water heater is to have some of the water leave the bottom instead.

Christine - probably so.

Charles - personally, I'm not even sold on the TPRV maintenance.  Has there ever been a documented case of a relief valve that failed to operate which led to a catastrophic failure?  I just trust them to do their thing.

Evelyn - yes, please be sure to re-read this blog before you decide to flush your water heater.  You might change your mind.

Reuben the quality fo the drinking water has a lot to do with it as well. Ideal water, with a hydroxide potential (pH)of 7 is neutral. if below 7 it falls under the acidic side, which can be more aggressive to the water heater and should have a neutralizer in the water line, and if it's above 7 it's alkaline or hard and requires a softener in the line. Well water can have the Ph variations, but city water is usually neutral at 7 and that may be where the water heaters last longer. An undersized water heater, because it's cotinuous firing will also go sooner than a properly sized unit.

Oh why did I have to stumble upon this entry?!?!?!

So yesterday after reading this I thought it would be a good idea to replace the sacrificial anode in my water heater...heading up to the hardware store I picked one up for about 15 bucks, no problem. Well then I had to get a 1 1/16 hex socket but they didn't have them without buying a $49 set. So now I'm into this project at 64 bucks. I get home and WOW talk about a hard bolt to get off! I pulled and pulled and pulled some more and guess what? The cold inlet started to leak at the union!! SOO up to the hardware store I go again for parts needed to fix the leak. No big deal I guess at only $4 but of course comes the work to connect it...

In the end I spent about 75 dollars and STILL didn't get the dang anode out so I just flushed the water heater. Imagine spending 75 bucks to flush your water heater!! Man I'm a knucklehead.

Kathy - thanks!

Karen - well water?  Yeah, you probably should.  My parents have a cabin on well water with a 15 year old electric water heater that has never been flushed.  I wonder what that looks like?

Robert - that works.  I've heard that on many water heaters, the drains get so clogged with sediment that they won't drain when it's time to replace them, and the drains actually need to be drilled out. 

Scott - when I first heard about the tip for the leaking drain valve, I went "Duh!  Why didn't I think of that!"  As for the anode rod, please read Vince's comment below (#57).

Posted by Liane Thomas -Top Listing Agent, Bringing you Home! (BROKER Allison James Estates & Homes BRE 01885684) over 7 years ago

Hi Liane, I think the tankless systems cost a lot of money but don't save you a lot of money.  Check out Jay's recent post on that topic -

Chris - possibly so.  I'd love to do a side by side comparison of two water heaters; one maintained, one not.  If I ever get to a point where I need two water heaters, I'll do this test.  Check back with me in about 15 years for the results.
