Came out to the General Dollar due to leaking hot water heater. Water heater is a 6 gallon electric AO smith located in ceiling of men’s restroom. Water heater is still under manufacture’s warranty (2years old). Leak appears to be coming from supply and return connections. Nipples for supply and return in water heater are galvanized and supply and return lines were plumbed directly to copper causing electrolysis, both connections are leaking. Thermal expansion tank above water heater appears to be ruptured and full of water as well. Went to get whole building pressure from mop sink and T&S 8” mop sink faucet’s vacuum breaker is blown. Recommend replacing. Highly recommend outing PRV on system. Back flow preventer is leaking. Which means some part of back flow preventer has failed. Recommend contacting Dean’s plumbing for back flow inspection. (937)- 372- 0821
