Not sure if this is a pump problem, but wasn't sure where to post.
Came home today and pump was running but not circulating. Wife had noticed it was loud a few hours earlier but didn't see anything out of whack when she looked - cartridge filter pressure was 18 or so. When I went down to look at it, the Vac-Alert (SVRS) stem (PVC that was supporting it_) was bent over as though it have melted and the rest of the pipes leading to the filter were hot. there was little to no water flowing through the pump - didn't spend too much time looking as I turned it off pretty quickly. there was no pressure in the filter and the vac alert was also reading 0. I closed the drains (2 skimmers and one main (with 2 heads)) and the return and opened the valve on the filter. Yesterday I had cleaned the filters and when I restarted the system, I had tried to open the inflow valves one at a time to prime the pump better. I don't usually need to do this but the prime seemed a bit slow so I was just messing around with it. when I had it closed down to one skimmer, I tripped the Vac-Alert. I opened all 3 inflow valves then and reset the SVRS and got full prime with no problem. Everything sounded good and the pressure in the system was good (16 at the filter and 0 on the Vac alert) so I went on with my day. swam in the pool later that night and all looked well.
Not sure what else to tell you as I don't know what the issue is. If the SVRS tripped again, would it heat up the pipes? Seems the heat must be coming from the pump (just checked it again and it is still hot after an hour.) Did the pump lose prime and then heat up and then the PVC melted? What would cause that?
Thanks for any thoughts or help.
