Expansion Tanks On Cold Water Lines
I thought water heater expansion tanks had to be on the Hot water line. I found two installations today with the tank on the cold water line. The first photo, the tank was connected to the main water line for the home. Any thoughts?

Re: Expansion Tanks On Cold Water Lines
I can't imagine that it would really matter. I guess you could refer to the manufacturer's installation instructions.

Re: Expansion Tanks On Cold Water Lines
They say cold water side, a few may allow on hot water side, however, they also state shorter life if on the hot side, however ...
They should not be mounted with their weight off a tee like that.

Re: Expansion Tanks On Cold Water Lines
Is that home made connection to the draft hood acceptable?

Re: Expansion Tanks On Cold Water Lines
Leaking because of lack of proper support on the tank or leaking because of all the polybutylene piping?

Re: Expansion Tanks On Cold Water Lines
What is not even close, I am lost. Yes the PB is in bad shape, even with the copper fittings. The manifold was corroded.
