I installed the Grundfos UP15-10SU7P/TLC Comfort Series 1/25 HP Recirculator Pump in my home a few years ago. It has run effectively for about 3 years until its comfort valve got stuck in open early this month (continuous hot water from the cold tap). Looking to replace this valve (~$60), I see that some users have had it break even sooner so it seems it may have a continuous-run life of about a year. The pump still works fine.
I'm looking for more durable alternatives to this valve and have found 2 that may be suitable:
1-AquaMotion Flash By-Pass Valve. I have installed it as a replacement for the Grundfos comfort valve but do not find it to work (no hot water) and am concerned about developing a leak in my plumbing or pipe burst if this valve remains closed. No functional specifications are available from the manufacturer. They say that it works with their pump only. [How does a valve know the brand of the pump at the hot water tank?]
2- AquaMotion AMK-ODR Valve Kit. Page 5 of this brochure (No technical documentation publicly available)
3- ThermOmegaTech CircuitSolver.
Any thought?
