I am moving my 80 gal water tank to a better location in my basement to give shorter hot water plumbing runs and be next to my furnace.
The old expansion tank was installed in "series" with the tank at the end of a plumbing run:
HWT = HOT WATER TANK OP = OTHER PLUMBING EXP = EXPANSION TANK CWM = COLD WATER MAIN CWM --- OP --- EXP --- HWT
In the HWT's new location it would be more convenient for me to install them like this:
CWM --- OP ----------------- OP ----- | | EXP HWT
Is the above a satisfactory install? Or would the below design better isolate the HWT pressure variance?
CWM --- OP ------------- OP ----- | EXP--- | HWT---
Put another way - does it matter where in the cold-water-system the Expansion Tank is installed? For example, could I just put it next to the Main without any regard for where the hot water tank is located?
