Cycling Water Pump

The fresh water pump was cycling 2 to 3 times an hour. I found and fixed a leaking fixture. The pump still cycles on and off 2 to 3 times in 24 hours even if no faucet has been used in hours. The bilge is now dry. Any suggestions? Thanks.

There could be a very slight drip from one or more of the faucets. Even a single drop every two minutes could cause this.

Re: Cycling Water Pump

The pump could be leaking internally.

Re: Cycling Water Pump

My water pump leaks a drop every few minutes- previous owner let it freeze. It never makes it to the bilge, but does cause the pump to cycle a couple times a day.

Do you have an accumulator in the system? If so, it might need bleeding.

Re: Cycling Water Pump

Put tissues paper in your sinks/shower under the faucet. If it leaks, you'll know. You can also do this with flour or talcum powder, but that makes a mess. If you don't have evidence of a dripping faucet, the pump is probably leaking by.

You could also shut off the pump when you aren't using it. I find we use less water this way, especially when we have visitors.

i second this if you can't find any leaks, all it takes is a tiny leak in the intake valve

Re: Cycling Water Pump

I found mine cycled less when I increase the pressure in the accumulator. It helped even out the flow too when I open the faucets.
