Water pump cycles on....

[KNMIB]

Probably not a new question but here we go. 2018 Coachman Leprechaun and this trip for the first time the water pump occasionally turns on for a couple seconds. My first thought of coarse is a leak but I have checked everywhere and can t find anything. So my intelligent friends do you have any ideas?

Sometimes the leak is inside the pump. A check valve leaking and allowing water to flow back into the tank. No external leakage of water.

Agree with Woody...cure could be as simple as running your pump for a day or so instead of city water.....or replacing the pump....or adding a check valve to the intake.

Thank You. It is not that often so I think at this point i will leave it be. Not a big problem.

Do you have an ice maker in the freezer? My pump will "burp cycle" during the overnight as it feeds the ice maker.

[KNMIB]

No we don't have an ice maker. No ice in beer LOL. Although DW might like one.

Could a shower be turned off on the wand instead of the hot and cold valves? Check toilet to be sure the flapper is fully closed other wise a small leak there is possible.

Just had this problem. Searched throughout the inside and could not find anything. Was outside and saw a wet spot, very small, beneath the low point drains. The hot side had a very slow drip. One per minute or less. Tighten the cap, no more water pump cycle. Should probably replace both caps now.

I replaced my caps with 1/4 turn valves.... Just saying.

There should be a little rubber seal inside each cap. The seals can drop out, unnoticed, when you take the caps off.

Pump failure is rare. Shurflo pumps work very well. I have had sand get into the pump, and make it run almost continously. Easy to disassemble the pump and clean it. But, usually when you have that problem it is a leak.
