Two water heaters, one house, other for detached garage washing machine. Never had expansion tanks installed.
Re piped and added whole house water filter system with bi-pass. Max psi rating is 90 psi for water filter canisters.
City pressure 145 psi, regulator set at 65 to 70 psi. (measured)
Each water heater can take closed house/garage system to 140 psi (measured).
Can I install a single very large Expansion tank anywhere in the cold water loop to cover both water heaters? Or must I have large individuals closely to each water heater?
Since each water heater is 40 to 60 gallons and max press needs to be at or less than 90 psi, individual expansion tanks are going to be 10 gallon (water volume, actual tank volume about 2 times that). Heafty size for installation locations.
