Common Questions

How do I know if my ASCO valve requires a rebuild kit?
Signs that your valve requires a rebuild include internal or external leakage, failure of the valve to open or close completely, or audible buzzing from the solenoid coil assembly. Using a 310-420-HW kit preserves the valve body while replacing all wearing internal parts.

Is this kit compatible with standard water valves?
The "HW" designation indicates this kit is specifically for hot water rated valves. While it may fit certain dimensions of standard valves, it is optimized for the higher temperature thresholds required in boiler or hot water circulation systems.

Can I install this ASCO repair kit myself?
Installation should be performed by a qualified HVACR or plumbing professional. It involves depressurizing the system, removing the solenoid head, and carefully replacing internal springs, seals, and the piston assembly.
