Here's the problem:
I went to clean the strainer basket from my Pentair Whisperflo WFE-3 and observed the following:
A. Flow in the strainer basket chamber is very weak and only half full.
B. The temperature got so hot inside the chamber that the plastic basket actually melted!
Other conditions:
1. Pressure gauge was reading less than about 3 psi. Normal is about 15 psi. I just cleaned and recoated grids three days before.
2. Pump motor was running; internal thermal breaker never tripped.
3. Pool has heavy algae and was undergoing treatment.
4. Pool water level was normal and flapper was operating normally.
5. I use a Kreepy Krawley that was operating normally the day before.
What condition(s) would cause my filter to lose it's prime? It's never done this before; I've had the system in place for about 4 years.
Thanks!
