Greater Johnstown Water Authority

To confirm that the Greater Johnstown Water Authority has adequate facilities to serve your proposed building project, all new construction customers should contact Dan Lovrich (814) 533-4300, ext. 125 or dlovrich@rdm-gjwa.com.

All customers are required to have a functioning backflow valve located downstream of the water meter. This backflow valve is part of the homeowner's private plumbing. We want to take this opportunity to forewarn you that there is a possibility that the backflow preventer may cause your water system to "pop-off", due to thermal expansion. Most often this causes your hot water tank to pop-off and discharge through the relief valve on the tank. In certain cases the thermal expansion may affect, and damage, other parts of your plumbing susceptible to high-pressure.
