Thanks, I will try the reverse direction thing.

They burnt up the motor by running the pump with little or no water somehow. Actually melted the pump basket a bunch to where it had to be replaced too.

The pressure gauge on the filter was at 30psi before I cleaned the green filter. Green from the pool water looking like pond scum. Got that cleared up in a couple of days.

Anyway, the pressure gauge is back down to about 18psi., which appears to be the norm after the solar panels were added.

How do I check the inlet fittings for tight connections?

Also, how did they manage to burn up the motor and what kind of pressure are you seeing at the filter inlet? That's what the pressure gauge measures, filter inlet pressure. Can be valuable clues as to what happened. If they somehow managed to run the pump with the return blocked, water in the pump but no flow, they may have heated the water to near boiling in which case regular PVC will soften considerably and air leaks could develope at the pump inlet fitting.
