Description
The NAVIEN TANKLESS WATER HEATERS 30010950A 1″ Plumb Isolation Valve Set Kit is a plumbing component used to control water flow during maintenance and servicing of tankless water heating units. It operates through manual shut-off valves that isolate the inlet and outlet lines, allowing safe servicing without draining the entire system. In HVAC systems, it is typically used in hydronic heating and hot water setups where controlled water isolation is required. Mounted along the 1-inch plumbing connections, it interfaces with supply and return lines for operation.
