Hi Guys
I have a 22SQE / CU301 system installed in 07/2006. CU301 went bad in 11/2009, and again now. (By bad I mean there is no constant pressure, just cycling constantly during water use.) I can get the CU301 covered under warranty (labor not covered), but am wondering if that's just kicking the can down the road a little. Well man says he recommends the Cycle Stop Valve, but I'm wondering:
1. CSV website says that pump (when flow is restricted by the CSV) will draw fewer amps. Why? Isn't it 'hard' on the pump to be fighting the restriction of the CSV?
2. I called Grundfos and their local distributor, and both said the CU301 is not unusally problematic. Reading here, though, it IS. Does anyone know how many of these are sold each year, and are we only hearing about the problems of the few who have them?
3.Biggest concern: I have a 1.25" incoming service. Would the corresponding CSV cause me cycling problems anyway? Specifically, when small amounts are used (ice cube refill,rinse dishcloth, etc.) which happens a lot here, wouldn't the pump cycle short? I think the min flow rate is 1 gpm; we often use less.
[Possibly pertinent info: pump is at 160'; static water level is 41';]
Thanks for the help, guys.
