I have a Sta-Rite Irrigation pump(DS3HF-01) that was leaking because the seal and diffuser ring were bad. After fixing the leak, the pump keeps tripping out the circuit breaker. I change the circuit breaker, the pump start relay, the centrifugal motor switch, and the capacitor. It still keep tripping out the circuit whenever I turn on the sprinkler system. It was working fine before I decided to fix the leak. What else could be wrong? Please help!
