Anybody ever see pvc explode like this?
Nothing blocked. All pop ups clear. Someone said an air pocket.
It appears to have a bit of air bubbles in the sight cover of pump.
Air bubbles do come out of some pop ups.
Pump was on high speed. 30 psi at filter.
It was after salt generator. Salt generator clean.
We had a freeze last week about 30* but freeze protection turned on.
