    hot water secondary return check valves

    Use a swing check valve, or a very lightly sprung non return. swing are best, as they won’t restrict the pump. But they will need fitting the correct orientation so the check valve falls to shut.

Eventually burning the motor out. you need to replace the entire valve, I would recommend a Honeywell as they work on...
