Bonsall pool pump losing prime questions

What causes a pool pump that will not hold prime in Bonsall?

The usual suspects are an air leak on the suction side, often at the pump lid o-ring and low water level letting the skimmer pull air. In Bonsall, aggressive calcium scaling from nearly pure Colorado River water eating away at plaster, tile, and pump seals can make some of these more likely. A technician confirms the cause on site rather than guessing from symptoms.
