Why would the pump stop suddenly while vacuuming the pool?

Answer 1

We have a vinyl liner which has been stretched from water getting under it when we have extremely heavy rains. When the vacuum head glides over this area it sucks the stretched vinyl into the hole. I have to pull the vacuum head hard to get it to let go. Sometimes it affects the the filter pull if I don't get it to release quick enough on my end. I have to wait until the filter regains its suction ability before continuing.

AnswerIt depends what you mean when you say "the pump stops". If you mean it quits pumping but the motor continues to run, that's because the pump looses suction for some reason like a hole in the suction line. If the motor stops running, that's an electrical problem and maybe that the pump is shutting off on it's overload protector. If so check the amps and volts to the pump and make sure they are correct.

You should turn off the pump before you try to remove the vac head then restart the pump after you have relocated the vac head in another area of the pool. K
