Common Water Heater Myths Answered | Ask This Old House

[@NorthPaddle]

I changed my anode rod today. I got super lucky and found them 80% off at my local Ace Hardware. a $6 fix to hopefully buy me a few more years on mine.

[@ullrsdream]

Wow that's a sweet deal. I replaced mine today and it had never been changed since 98-2000. All that was left was the metal threads and swollen PVC at the top.

[@jeahhh]

Great work cheapasss

[@ullrsdream]

@m rapacki it's such a champ, I'm excited to see how long it lasts! As far as planned maintenance, yep it's a known aged element that will go. But judging from the reviews of much newer water heaters, this one very well could outlast a new one. This is one of the cases where they don't make them like they used to. Then again, they didn't used to make all plastic ones or tankless. Everything changes. (Reviews from the UK find it absolutely nuts that Americans are replacing steel water tanks every 5-10 years, and I tend to agree)

[@IrrationalBstrd]

@m rapacki when I bought my house and moved in, I had a hot water tank in there that was probably 30 years old. Ruud Copper-nickle was the name on it. It had a retro looking sunburst logo stamped out of brass or something like that on it. It finally leaked after having the house for about 3 years. Ive noticed on a lot of stuff made in the 50s, 60s and 70s that makes their modern day counterparts look like a tin can. Everything is throw away anymore, made as cheap as possible for the most money possible. Edit: I did a little research and that tank was around 50 years old when I took it out.

[@IrrationalBstrd]

@m rapacki sorry, I edited my comment too late. I did a little research, and I'm sure it was the original tank when the house was built, 1960. So 53 years old when I removed it.

One thing that Richard (uncharacteristically) forgot to mention is truning off the power to the unit. Weather it be electrical or ntural gas (or LP) power needs to be shut off when draining the tank. Heating element can be damaged or destroyed by remaing on with no water to heat.

[@R900DZ]

The way he described draining it involves keeping it relatively full of water the whole time (more of a flush than a drain) so elements should be fine

[@dormandavis2767]

When I install a new water heater I install a ball straight valve in place of the drain valve to make it easier to flush. From my experience as a handyman for 35 years it seems like they last 7-10 years on city water with a lot of crud buildup. I have well water in my house. My water heater is 15 years old and still chugging along with no crud build up. I’ve changed out a water heater 4 times in the same house. For some reason well water doesn’t leave crud behind sometimes.

Draining the water is really important. I replaced my stock drain valve with a brass 3/4 ball valve setup. Why? The OEM plastic drain valve opening is deceiving; it accepts a garden hose size opening, but the inside port has a small hole. This restricts the bigger chunks of junk from your water heater from flowing out. With the new setup, I was able to flush out the bigger chunks. Then, I calibrated the water heater and was able to turn down the thermostat dial down a full notch. Improved heating efficiency. Got my parts at Home depot: water heater nipple>3/4 ball valve>3/4 MGH-3/4MIP brass adapter.

It also doesn't help that the thermostat's probe in the tank can get covered with minerals too.

@mark broad, yep, just replaced an A.O. Smith that I had for almost 20 yrs. I drained it down a few times over it's life, never touched the anode rod. They didn't mention it in the video but people should also be mindful about shutting off the gas or electricity for electric water heaters when draining/servicing. It's also a good idea to put the water heater in a pan AND to route the relief valve to the outdoors in the event it fails or opens due to temp/pressure surge. It also helps to install a thermal expansion tank. What had bothered me about new construction is so often water heaters being installed in the attic space, considering that pans do corrode and can leak eventually and the fact that a gallon of water = ~8.33 lbs (3.77 kg), multiply that by 40, 50, 75 to 100+ gallons and that's a lot of weight in water sitting overhead.

If you try to drain the tank you have to open a faucet so it can pull air in from the hot pipe or it will take days to drain

[@mikeratkowski3506]

Lift the lever on the pressure relief valve, couldn’t be simpler

[@ullrsdream]

Or pop the over pressure valve on the side of the tank and it lets water in right there (use a bucket or hose to catch / direct any water)

[@jaycahow4667]

The proper way is to add an air bleeder valve into the plumbing above your tank which allow air in as the water drains out. If you are draining the tank to replace it with a new one then by all means open the pressure relief valve while trying to drain it to let in air. If you are planning to keep your current tank and are just partially draining it or flushing it then I would never open the pressure relief valve as it might not completely close again. Even if it closes it might increase the chance of it accidentally opening at a later date. Either open a hot water faucet or permanently add an air bleed valve to increase the drain flow rate. This assumes you can actually drain anything in the first place as many times build up inside at the bottom of the tank covers over the drain hole to the outside. Periodically draining some water from the tank helps prevent this.

[@MrLeedebt]

Australia here. I have some plumbers coming in about 5 days to put in a new electric hot water heater. The old one is made out of copper (it's 50 years old) The only thing wrong with it is a leaking header tank.

[@wholeNwon]

What is a header tank? Is it what we call and expansion tank? If so and if it's the only thing leaking, obviously it's what you'd replace. If you have the strength, it's a very easy DIY job. I just cut off the water and drill a hole in the bottom of the expansion tank to drain the water it contains into a bucket. Otherwise it will be very heavy. Unscrew it and screw a new one on using some teflon tape and pipe dope. All the home stores sell them.

Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

We built our house in 1986. The water heater that was installed lasted 32 years.. It's a 52 gallon Mor-Flo. I could have it repaired (it's the element or the thermostat) but was advised that newer models are more energy efficient so I should get a new one. What is your opinion - repair or replace? We have super hard water with sulfur and the tank may have been drained once about 25 years ago. I don't know if it ever had one of those anode rods.

I have a really old heater that has never had anything fussed with it since it was put it 20 years ago. Still heats water good and lasts a while too for those long showers. This was back when Kenmore actually had great build quality.

Kenmore never built anything. That was a rebadged water heater made by one of the major manufacturers. Our water heater was a cheap builder’s model made by State and it lasted 16 years. It probably would have lasted more than 20 years had I changed the anode rod.

[@shortfattoad7317]

So where we live, we have to have an inline water filter from the mains supply, also, many have water softeners. This keeps everything running better. Couple this with a 4-5 year descaling service and normal maintenance, our 300 litre water heater is running perfectly for the last 33 years. Yes 33 years and only now we are think of having it replaced for a newer model. Only because, well 33 years!! During the service the magnesium anode rod is always replaced, this service was just quoted to us for around $850, but a new replacement will run about $3200.

[@orbitring]

One thing is a "MUST REMEMBER" . . . IMPORTANT to turn-off your natural gas feed to the tank, at the control center of the water tank FIRST. You do not want an explosion because of the lack of a water feed supply to the tank. After you clean or drain out the tank and have turned the water feed supply on to fill the tank then, reignite your pilot flame.

I have heard the suggestion to periodically drain the tank to remove sediment. Yet, several people who have done that have emphatically said 'Don't do it'. Their experience has been that some of the sediment will remain in the drain valve, preventing it from fully shutting. This caused a leaking drain.

[@nnamerz]

[@gregparrott]

@@JackTRyan After 21 years, I preemptively replaced my gas water heater rather than risk a failure while I'm away from the house. One of the steps was to drain it. Essentially no corrosion, scale or other buildup appeared. The tank likely could have lasted much longer. However, our water is good quality. If we had 'hard' water, I expect life expectancy to drop off by a LOT, and there would have been a lot of scale. My guess is that periodic draining might make sense for hard water. But, be prepared to place a sealing cap with mating threads over the water outlet, just in case scale lodges in the valve mechanism and prevents it from fully closing.

Thanks guys and great content as always. With your videos I was able to replace my leaking T&P valve and anode rod and flush my water heater a few weeks ago. I also used a video borescope to look inside the tank while I was servicing it and see the coating inside the tank was still in excellent shape and the anode was still doing it’s job.

[@gregriley3060]

I believe my anode rod is part of water inlet, so you have to cut the connecting piping to get the anode rod out. Further, the tank is in the basement and there is not much clearance to get the old one out, and the new one in. Thus, it doesn't seem worth it. I installed mine on blocks with a pan. The drain form the pan is connected to a condensate pump. Hopefully that will save me unless there is a large rupture.

Must have some good water here, my previous water heater lasted 20ish years, and my current one has lasted close to that as well. Sure I needed to change the thermocouple a few times since that tends to die out, but never changed that rod thingy. Wonder what those different warrantied water heaters do though, do they just give you a bigger anode rod? Would love to swap out to a tankless, unfortunately the location in the basement the water heater shares a flue with the furnace and goes up through 2 stories of house. And while swapping out the flue for a double lined one is not that much of an issue, from what I understand you can't share the vent pipe. Plus I'm sure my gas line isn't big enough too.

I've got a Rheem that is still working (the bottom heating element is out, though) that was installed in 1978. Never flushed, never changed the anode rod. I'm afraid to change the bottom element, afraid it will break something if I try to take it out. I replaced the top element, and that took an air impact wrench to break it loose. I have a replacement heater, I just have not installed it yet. I think part of the reason it has lasted so long is because I have very hard water with a high pH.

[@toprudder1]

@m rapacki Not to be contrary, but if what you say is true, then explain why my water heater has lasted for 44 years, with high pH and very hard water?

[@toprudder1]

@m rapacki You said hard water is not good for water heaters, which I DON'T disagree with, but still my water heater has lasted 44 years. I can't explain it. General wisdom doesn't seem to explain it. That is all I am saying. There was a discussion I was reading about the lead problems in the water in Flint Michigan, which started after they changed water sources. There was evidence to suggest that the original water source had minerals that coated the inside of the old lead pipes, which reduced the amount of lead leaching into the water. When they changed the water source, the softer water caused some of the minerals to dissolve away and that is when the lead levels rose. I'm just suggesting that something similar may be going on in my WH with respect to mineral buildup. I have a neighbor that has very soft, and acidic, water. He has had numerous problems with his copper plumbing and water heater (pin hole leaks, etc). My house is 44 years old, I have been in it for 26 years, and to my knowledge there have been no problems with leaks at all. The water is hard, and a pH of 8.0. That would seem to suggest that soft acidic water is worse for plumbing than hard alkaline water. Unless, of course, something else is going on that I don't know - which is entirely possible. I'm not a chemist, so I may well be ignorant - which is why I asked the question, I would like to learn.
