Expansion tank, is this correct?


My previous house, which we know rent out and during an inspection we were told to get the expansion tank fixed and add another seismic strap to the water heater. The strap is no problem but can anyone see an issue with this expansion tank?

Am I correct in what I am seeing. You piped from cold into tank then into the hot side of water heater?

It is better if the expansion tank has some additional support from below or some suspension from above. The strap is correct but should not need to be tightened ever so tight so as to keep the expansion tank from sliding down and out.

No, cold into expansion, into cold side of hot water heater. Hot side of heater goes out to the bathrooms, etc

I'm waiting on a call back from him. The report reads "Water heater missing proper bottom seismic straps and expansion tank. Consult licensed plumbing contractor to view and repair as necessary."

I agree, wait and ask him and get clarification. Its possible he may have somehow overlooked it.

My guess would be he was too quick with his cut and paste while he was doing his report , and it should state:

"Water heater and expansion tank missing proper bottom seismic straps Consult licensed plumbing contractor to view and repair as necessary."

Re: Expansion tank, is this correct?


Is there a seismic strap on bottom portion of the WH or just the top? They evidently need two; one top and one bottom.c

WH needs seismic strap at the top 1/3 of tank and bottom 1/3 of tank- this is assuming your're in a zone that requires seismic support.
Expansion tank is fine.

Just the top strap right now, so I assumed he just wanted the lower added, but the expansion tank confused me. Cant imagine the expansion tank needs an upper and lower strap

With the flexible connections to the tank yes the expansion tank needs strapped. And if you used PVC on the T&P relief I would have turned that down also.
