The step-saving Pro-Pal Dielectric Water Heater Supply Valves (DWHSV) simplify the installation and service of any water heater, combining a dielectric union, a ball valve, and a 0.5 in. (12.7 mm) FIP vacuum relief valve port into a single forged dezincification resistant brass body.
For areas where an expansion tank is also required, the Dielectric Water Heater Supply Valve with Expansion Tank Service (DWHSV-X) is a fully integrated solution. It features an extended arm with a 0.75 in. (19.1 mm) FIP port and 0.75 in. (19.1 mm) capped hose drain. Both models are available with or without the vacuum relief valve and user choice of FIP, MIP, sweat, press or push ends to connect to system piping.
