    Booster pump killing main pump

    So today I went outside and noticed my main pump was off, I typically run it 24/7 so this was strange. I reset the breaker and it came back on. I tried to use my booster pump but when I flipped the switch my main pump went off and the booster sounded weird. I shut the booster off and the main pump was dead again. Any ideas on what's going on?

    It could be bad pumps, switches or breakers. Test for voltage going to each pump.
