My original hot water heater had an expansion tank. When the water heater needed replaced I had a friend install a new one for me. He said that I didn't need the expansion tank. Unfortunately, after a very short time my new water heater started leaking due to not having the expansion tank causing too much pressure ruining my floor and main valve where water comes into the house. I really appreciate that my buddy tried to help me out, but it would have been much cheaper to have a professional install my new water heater.

Hi Rush - the 2 devices are meant to handle 2 entirely different things: The T&P valve is meant to deal with an emergency situation where the pressure or temperature in your heater tank has exceeded the threshold of safety for the tank construction. In short, the T&P is there to open and relieve pressure if the tank ever gets severely over-pressure or too hot. An expansion tank's job, on the other hand, is to protect the rest of your entire hot side of your plumbing system from the completely normal slight expansion that happens whenever you heat water. It used to be very common for your water supply to run on an "open" system, where as water expanded a bit it was allowed to backflow up your water supply line back out to the street. Most newer construction has done away with this, and new homes are being built with a "closed" system... i.e, there is a backflow preventer on your cold water supply, so as the water in your heater expands during the normal operation of the heater, it stresses all the devices connected to your hot water supply. Don't take my word for it though - bang around on Google for a few minutes looking for something like "do I need an expansion tank" and you'll find far more info than I can share here. Thanks for watching!

Expansion tanks are the least reliable thing in your system. I eliminated mine and checked the min and max pressures with gauge with a full cold to hot tank transition. If your water pressure is low enough, the extra 20 psi caused by heating water won't hurt a thing and you don't need one of these. Pressure gauges are cheap. If it's rare that you use all the hot water in your heater, with only heating half a tank the pressure increase is lower still. Expansion tanks are 3x the cost of relief valves. Change the relief valve every four years if you're worried about it. The real crime is installing an expansion tank on a system with a tankless heater. The plumbing lobby is strong.

The Amtrol unit you uninstalled carries a 10 year warranty. The second one you showed comes from Home Depot and only carries a 1 year warranty. Also the original Amtrol unit was installed upside down. I have the same Amtrol unit and my instructions say it has the be installed with the air/schrader valve on the bottom. I mounted the new tank on an expansion tank bracket and used a stainless steel flex line to go from the cold water line into the top of the expansion tank. I used the mounting bracket because I didn’t want the expansion tank putting stress on my cold water copper line and definitely didn’t want to use galvanized pipe.... For future reference the Amtrol brand is a much better expansion tank than either the generic Home Depot or Lowes branded expansion tank. You do get what you pay for there. The video was an excellent explanation. Just always follow the mounting instructions that come with the expansion tank you purchase as the new tank may not be able to be mounted the same way. Ron

First of all, a HUGE THANK YOU for your video and your thorough explanation on the expansion tank. You saved me a few hundred dollars because I had an issue with a leaking pressure valve. I thought it was the pressure valve, so I replaced it and the leak continued. I thought it might be the thermostat on the water heater and it was overheating the water and causing the pressure relief valve to open up. I also checked into the water pressure, 80psi and I called the water dept and verified that it wasn’t high since most places are around 60psi. They told me that they run around 85-100psi, normal pressure for their system. I’ll probably add a regulator later, but I checked the expansion tank’s Schrader valve and water came out! I replaced it and filled the air pressure to 80psi. The old tank had rusted through on the tank’s 3/4” nipple and I doubt the plumber added the correct pressure either. But to make a long story short, you helped me by saving me money and if a “like” and “subscribe” is enough to say thank you, I’ll do it in a heartbeat.

Thanks for your thorough video. I actually discovered that our tank was faulty (spouted water when tested) while trying to troubleshoot some really high pressure in our system (which I began to suspect because we were having all sorts of valve and cartridge failures around the house). At first I thought we just needed a pressure-reducing valve and got one installed, but we still had high pressure. Some more research indicated that the expansion tank might be the problem, and so then we got a new one installed. In my research, I had seen that the tank's pressure needed to be equalized with the house pressure, so I asked the plumbers whether they had done so and they said, "no, it comes pre-set" (to 20 PSI). Well, I knew that was an issue, read the instructions that came with it, and verified the proper procedure. So here's my point: The house pressure would sometimes get over 100 PSI. Measuring the "house pressure" would then indicate that the tank needed to be set to this, which I know was too high. I let the water run for a bit to reduce the excess pressure, then measured 45 PSI. I ended up redoing part of their installation then by doing what you first showed in this video - turning off the water, releasing any pressure, adding some air to make it 45 PSI, and then turning everything back on.

Ironically moved into a city that does not have water pipe input code to install a check valve, and when a contractor broke our water line several blocks away drained all the water in our home so I couldn't even a cup of coffee. Was water in the toilets didn't want to use that. So I installed a check valve but also had to install a water heater safety tank, and like yours on the cold line intake. Mine does have a Scharder valve on it like on your car tire to check and add air pressure equal to the water pressure. Ironically a city worker knocked on my door and of all things wanted to install check valves on my two laundry tubs in the event city water pressure would drop, had my tubs full of dirty water is a garden hose in it and the faucet was left on. Ha, if anyone left that faucet on, house would be full of water. But told him I didn't need one because I have a whole house check valve, not a cheap one, solid brass. Got a hold of the city mayor, building inspector, and others, just told them practically in any city this check valve and safety tank is code. They didn't know this, know it now. By adding this check valve and safety tank noted my water tank heating bill went down, yes, water when heated does expand, can't go out the hot side of the tank as all the faucets are closed, but does go out the cold side without a check valve, so way paying to heat the city water supply as well.

The following day my water tank spewed about 2 1/2 gallons of hot water from a copper release pipe. I contacted a plumber who informed, after tapping on the expansion tank, it had a calcium buildup preventing proper water flow through the system which caused the hot water leak. He added the expansion tank needed to be replaced. 😒 He did not do a water pressure check from an outside home water value to see if it matched the pressure from the expansion tank. Could I have been duped into a $350 purchase for an expansion tank that did not need to be replaced and only required a simple fix? I had the original expansion tank for about 5-years.

Hi Johnny - whether you need one or not pretty much depends on your water supplier. If they require a backflow preventer on your hookup to the main water supply, you'll need one of these.

If you don't have one, and have never used one, your system likely does not need one (unless you hear otherwise from your water supplier). Thanks for watching!

Hi John! With some tanks the orientation matters, but the instructions for this one specifically allow orientation in either vertical orientation. If you are replacing yours, pay attention to the instructions to make sure it is installed correctly. Thanks for watching!

Thanks for that feedback. The one I will be replacing is made by a company called ProFlo, Model PFXT5. It was installed by a well-known reputable plumbing company in my city and they installed it in the same orientation as yours, except they didn't use a support bracket which I think I will add to the next one I install. So since I didn't receive the installation instructions, I guess I'll have to assume they know what they are doing and if I purchase the same unit from another reseller myself I guess I'll install it the same way unless, as you stated, I should check the manufacturer's instructions as the final say. Thanks.

Thanks for the great video! My T&P valve is plumbed directly into my sump so I haven't noticed any slow drips. But I have noticed intermittently that the pressure when I first turn the water on is significantly higher than typical (after watching this, I expect it's probably right after a heating cycle has run). Checked the pressure on my tank per your video, and sure enough, had water coming out of the Schrader valve. Guess I'll be getting a new expansion tank for Christmas!

Thank you for the video! I have a question, what will happen if expansion tank have too much pressure?
@AmplifyDIY
3 жыл бұрын
Hi Huyen! Great question! When the water in your water heater is heated, it expands. Unlike air, water cannot be compressed into a smaller volume when it is pressurized... so when it expands as it heats, that additional water volume *must* go somewhere. With your expansion tank pressurized properly, the water will expand up into the expansion tank reservoir. If the tank is over-pressurized, then the water will find it's way out through whatever offers the least resistance. If you are lucky, as the pressure in your plumbing raises up to be equal to what is in your expansion tank, all your fixtures will hold the increased pressure and the water will flow into the expansion tank. If you are unlucky, the increased pressure on the hot side of all your plumbing will break a fitting *somewhere* - most often it's at the back of a washing machine. Bottom line? A small difference in pressure is probably no big deal. But don't over or under pressure the tank a ton. Pressurize your expansion tank correctly, and check it at least annually. Good luck!

Interesting and well presented. How prone to failure are the bladders? The way yours is mounted, if the bladder fails and since the tank doesn't leak, is it OK to just add air and re-pressurize the tank
@AmplifyDIY
4 жыл бұрын
The bladders are pretty resilient as long as the tank is kept pressurized. Most failures happen prematurely because the plumbers that install them never bother to pressurize them correctly (that was the case with mine). Simply re-pressurizing the tank is not a great idea if your bladder has failed though, because inside the tank the area behind the bladder is not protected against corrosion, and by letting water that has been behind the bladder get into your heater tank you'll introduce all kinds of crap you really don't want in your water supply. I actually cut one of these open that had failed (filmed it, but never finished the video... maybe I should) and the water inside was a goopy, sludgy, rusty, foul-smelling mess. If your bladder has failed, just replace the tank.

I've gotten lots of feedback from viewers letting me know what a bad idea it is to use galvanized. I guess the professional licensed plumber who installed all this when the house was built didn't get the memo... but it's on my list to replace. I've heard brass or copper are better options.

@@AmplifyDIY Yes, the Everbilt and the Watts are two where the manufacturer allows vertical mounting in either orientation. That Amtrol tank that you had originally however, was mounted incorrectly according to Amtrol and needed to be fed from the top, not the bottom (eg., with the label right side up). I have a Watts DET-5 that is supported entirely by the water heater, and it is blown (water coming out of the Schrader valve, 9 years old). I have an all-copper soldered tubing system and I am considering re-plumbing the cold water side so that I can have a top-fed vertically wall mounted tank which relies on the wall bracket and not the heater for support (I enjoy soldering btw and I am pretty decent at it). This configuration will also allow me to use any brand tank (since they all support vertical top-fed orientation) but only a handful support the vertical bottom-fed orientation. Your videos are really, really good and have been a great resource to me. Brilliant work!
