What it delivers

The HYDRO MASTER 0560301 Tankless Isolation Valve Kit is a pair of tankless service valves for flushing and isolating the heater.

Service valves let you shut off the heater and open hose ports on the hot and cold lines, so a flush takes minutes instead of cutting pipes.

Before ordering, check the heater's fitting size and whether you want threaded, sweat or push-fit connections; the hot-side valve usually takes the pressure relief valve.

From the listing: connections: 0.75 in; material: Lead Free Brass; model: 0560301.
