How long should a well pump run before it shuts off?

So a minute on and a minute off has always been the minimum rule of thumb. Two minutes on and two minutes off is just that much better for the motor. With the old conventional pressure tank method, the pressure tank fills at the rate the pump can produce, less the amount of water being used at the time.

How often should your well pump turn on and off?

Depends on the size of the pump. Even 1/2 HP pumps are recommended to have at least a 1 minute run time. Actually it stated as 300 cycles per day. And since there are 1440 minutes in a day, that would be a cycle every 4.8 minutes max.

Why does my water pump only run for 10 seconds?

It always used to work OK, but after not using it for a period of months, it now runs for about 10 seconds, then cuts out for 2 or 3 seconds, then runs for 10 seconds again, etc. I have tried undoing a bolt on top of the pump and pouring in water (hopefully a prime) but it doesn’t help.

How long does it take for a well pump to stop working?

Ever since I bought the house, 14 years ago, the pump has stopped working after approximately 30 to 45 minutes. At that time you head on down to the basement and lift a lever to increase the pressure. After the pressure increases the pump works fine.

How does a submersible pump start and stop?

There is a small start relay that controls *only the capacitors.. its not the pump control relay or pressure switch that start relay lets power flow through the start capacitors only for 2 or 3 seconds during the pump motor start phase. See the diagram at the link below.

When does back feed drop below pump cut in pressure?

When that back-feed drops building water pressure below the pump switch cut-in pressure the water pump cycles. This intermittent well pump cycle will continue until the water pressure tank has also been pressurized to above the pump cut-in cycle. Thanks to reader K.K. for this tip 8/43/2014 and who wrote

When does water pump cut off at 50psi?

When it drops to about 48-49 psi it cuts on again and cuts off at 50psi. This happens when no water is being run. cuts on and off every 5 minutes or so. Help. I have an 80 gal tank (old style) where air and water are not separated by membrane.
