Hello all,
I'm a new home owner in Puerto Rico. Most homes here have above ground cisterns and pumps for emergencies. Many homes are also constructed of reinforced concrete/cinder block for the same reason. This is good, but unless you witnessed the construction (or have good blueprints), determining the plumbing layout can be puzzling. The situation I've inherited is that when I lose city water and turn on my pump, I get hot water to my cold water faucets and I can hear water reversing through my electric water heater. A friend of mine has a check valve on the hot water side of the heater to prevent this. Is there a downside to this type of modification?
Thanks,
Bill
