Check your Expansion Tank pressure once a year to keep you hot water heater Safe. The Villages Fl.

You don't have to live in the Villages Florida to check your water heaters Expansion Tank pressure...it's easy. You should check it once a year and refile or replace it if needed.

When checking air pressure of an already installed expansion tank, you first have to shut off the water main valve so that there is no water pressure coming in; then you open some faucets so that you relieve the system’s built up pressure. After that you can get a more accurate measure of the air pressure in the expansion tank, and fill it to the appropriate pressure. And you do not have to drain the water heater tank to check the air pressure.

Thanks

[@karamario6295]

Thank you you answered the question in my mind 😂

[@heinzotto1194]

Yes, I was also wondering that. Also, if you fill the tank with air that matches your water supply pressure, no water would normally enter the tank, right? So the expansion tank would be 100% air, not half filled with water as he said at the beginning of the video. I think the factory pressure of 40 psi is adequate if your supply pressure is 70 psi. Some water will enter the tank until the pressure equalizes, that’s how it was designed to work.

@@heinzotto1194 Your later points are incorrect. As the water expands, it enters the expansion tank and compresses the air or bladder inside. When the hot water is used, and the temperature decreases, the water inside the expansion tank is pushed back into the main water supply. remember to check the pressure of expansion tank often. It can loose pressure just like your car tires do, more so in fall, when outside temps fluctuate.

Good job Rusty . . . Dr. Roy Hinkley would be proud.

[@ronaldpass8885]

A thermal expansion tank is only necessary if the water heater is part of a closed system. A closed system is created when there is a check valve in the incoming water supply that prevents the expansion of heated water from flowing back into the water main.Jul 26, 2019

RUSTY,my street pressure is 120 psi,but has gone as high as 130psi,so I installed a PRV, PRESSURE REDUCING VALVE,set to 65 psi,all has been as of 1976,when I moved in., 🇺🇸🇺🇸🇺🇸🇺🇸

[@RustyNelson]

It can get high and when it does it can also damage things. Subscribe for new Videos: bit.ly/3aToJ3H

Thank you Rusty you are awesome with a lot of helpful information

[@stuntz0rZ]

The tank should be mounted such that the process connection is at the top, so the air bubbles can rise up and out of the water side of the tank. If the tank is on its side, air can get stuck inside and cause corrosion at the steel tank wall.

[@smartyyy]

funny enough my tank is corroded a the top from water escaping and sitting then slowly dripping down

thank you.

thank you for your time and video.

I went to check my relief valve plumbing, it seems to exit outside the home. I'm a little surprised on our water pressure (located south of 44) it was approaching 75 pounds. Thanks!

[@ln5747]

The outside tap may not be the same as much of the rest of the house and subsequently the expansion tank. Depends if it's coming off a balanced supply or the main. That's why it's not a case of simply matching the tank pressure to outdoor tap pressure.

[@jcaleca60]

The expansion tank mounted wrong should be vertical, not horizontal 😮😮😮

[@BeeTreeGuy]

My house water psi is set at 55. I set my expansion tank psi to 55. I have a dedicated bib that I keep a pressure gauge on, why would it show 90psi after the water heater completes a heating cycle if the expansion tank is supposed to keep the water psi equalized?

[@craigboots7929]

It will go up because of the heat of the water expanding , but up that high , you might want to check and make sure the tank is working properly and not leaking air . Shut off main water valve, drain lines to relieve pressure and THEN check pressure in tank, if you set it at 55, it should still be around that pressure , if it’s low, check and see if the valve is leaking air or the bladder might be leaking ?

[@kaylajacks5670]

Rusty! Thoughts on how to replace our boiler expansion tank that has glycol in the system, but does NOT have an isolated valve to the tank?

[@mightyj806]

I have an inlet pressure reducing valve pre set at 12psi. Yet my boiler runs 20 psi cold and almost 25 psi hot. The expansion tank also precharged at 12 psi. My home is only one story (with basement where the boiler is) and the highest piping point is about 8 feet from the boiler. The boiler was installed with the expansion upside down, meaning valve stem points towards ceiling. The circulator was installed right before the return into the boiler. When the maintenance guys come they always say that's ok. I don't believe it. Would adding or reducing pressure from the expansion tank help the problem because there doesn't seem to be any other way to lower the pressure?

[@user-fs1uf1px2k]

What if you test the tank valve and no air or water comes out?

[@RustyNelson]

There is a leak someplace. Subscribe Button for new videos: bit.ly/3aToJ3H

[@softmetals3702]

what good is the bucket if the pipe is almost to the bottom so when it fills you basically have to dump it while taking it away, maybe cut that pipe otherwise great info

[@123456bmx]

Smart people use a cup to empty the bucket 😮

[@rhodiafiddler5557]

We had the water pressure checked at meter and it was 100 psi. Our house is about 200 feet down hill from the meter. Should we still check it again at the house?

[@nilolee2426]

Mine was installed and mounted horizontally ,does it matter or it’s bad idea?

[@RustyNelson]

I would just make sure it is braced well. That's the way mine was in my other house. Subscribe Button for new videos: bit.ly/3aToJ3H

[@davidoverholt251]

Just make sure you have an insured, bonded, licensed plumber within your state requirements to check your water supply and water pressure! Between 35 and 75 psi, you have a questionable problem!

[@RustyNelson]

Yes if you are going to have a plumber do it. But this is an easy check for a home owner to do once a year. Yes if you are pushing over 80psi you need to look into it I believe. Have a great day and thanks for jumping in.

[@DisMindy5767]

Nope. We don't have one of those expansion tanks on our water heater. And no it's not a tankless system. We have 3 levels and 5 bathrooms.
