From what I've read on here, my pump is losing its prime? It happened once yesterday. We noticed one of the returns was gurgling loudly. The water in the pump basket was swirling like a hurricane. We shut the system off and took off the lid. The gasket (? black rubber ring) looked perfect - in place and no crimps. We tightened it back, and all ran fine for the rest of the evening.
This morning, the pool came on at high speed as usual. I checked the pump basket - looked great (couldn't tell it had water in it). When it shifted to low speed, the same thing happened as last evening.
Should I do the remove the lid thing to prime it again? Is there a better way? Leave it alone til I can call my PB tomorrow (rather not bother him on a holiday)? Or best yet, is it an easy fix I can do?
