What it delivers
The MEASUREMAN MD124 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: 3/4 inch connections; model: MD124; warranty: 1 year.
The listing gives dimensions of 8 x 5 x 4 inches, a weight of 2.87 lb and valve in the box.
Warranty, per the listing: 1 year.
