Got the replacement pump swapped into the basket today. I didn't see anything wrong with the first install. I pressure tested the retention valve inside the supposed failed pump before I removed it. I attached to the pump outlet on top and pressurized it to check the retention valve and also so to check for leaks in the tubing. The pressure held...so it could be the 1st pump itself failed. I still need to look at data with the replacement I just installed to be sure but that will be done in a day or two.
