submersible pump ?

[willl]

Hi, I have a submersible well pump. I have an option of weather or not to leave it on continuously during the night or have it turn on and off maybe about 5 times during the night to repressurize the system (tank etc.). Which option is better for the pump. Thanks

... leave it on continuously during the night or have it turn on and off ... to repressurize the system ...

Where would the system pressure have gone, and what do you have planned for the pump during the day?

if there is water flowing it is almost a horse a piece. if there is not water moving then let it turn off and stay off.

if there is not water moving the motor will cook in the heat it creates.

if there is water moving it is hard to say. a motor technically only has so many starts in it. this might be 1000, 10000, or 100000000 starts. we just don't know, but we do know that every time a motor starts it weakens the insulation on the winding which in the end will cause motor failure. so, do you want to plan for the pump turning on and off or do you want to just let it run? good question. but it is very important that there is a cooling flow of water past the motor.
