Replace thermal expansion tank

No talking, just a man working. Nice job!

that expansion tank will fail too. You need to lower the pressure in your house. It should never be 80 or above. If you have a pressure regulator on your water line coming into the house, you need to set it to around 65lb. If it won't set, replace it. If you don't have one, get one. You are going to have leaks and maybe even broken pipes

Thanks. I dont know anything about those, but I'll look into it. Is it hard to do? video recommendation?

Look up pressure reduction valves. Usually they are mounted outside the house where the house shut off valve is. In cold climates this could be in the basement where the water line comes into the house.

@@Grant.Miller Also, there is often a front hose bib that is before the PRV and it will read the street pressure. Just to be sure, check your pressure from another another fixture. Then if its still that high, you def need to have a PRV installed or replaced if you have one already

That expansion tank won’t work because your water pressure is higher than the tank, but it’s too high. The tank should be same as water pressure.

[@brucestorey917]

You didn’t show what pressure you charged the tank to. Your system is ~120psi, which is too high, anyways, but you can only charge an expansion tank to a maximum of 80psi. What did you do? Incorrectly charge your tank to ~120psi, or lower you your system pressure to a max of 80psi and charge the tank correctly?

[@ranger178]

that is crazy high pressure might be reading pressure before the pressure reducing backflow preventer valve which is why you would need an expansion tank you could just put pressure gauge right on hot water tank to see what it is there then set expansion tank a bit lower. seems like an oversized tank for hot water heater.

In your garage, you don't have an air compressor? Lol!
