1. Make sure your pressure gauge is not broken: it should be near 0 when the pump is off, and should read least than 20 psi when the pump is on.

2. Two common causes of loss of flow are (a) filter plugging with algae (does your pool look swampy?) OR (b) a suction leak causing loss of prime (is your pump above pool water level?)
