Isolation Valve Kit Installation in Eagle, ID
Some tankless heaters were installed without service valves, which makes proper flushing very difficult. We install a set of isolation valves with purge ports on the hot and cold lines so future maintenance takes minutes. The kit also lets you shut off water to the heater without closing the main. It is a one-time upgrade that pays for itself in easier service.

Condensing Unit and Neutralizer Service in Eagle
High-efficiency condensing tankless heaters produce acidic condensate that must be neutralized before it goes down a drain. We inspect the condensate trap, line and neutralizer cartridge and replace the media when it is spent. A clogged trap can cause shutdowns or water leaking inside the cabinet. We also check that the line is protected where it runs outdoors.
