Water pump cycling

I winterize my MH myself by disconnecting feed line to water pump and bye-passing the water filter. Now after de-winterizing the water pump is cycling and it did not before. I check for leaks and I cannot find any. I increased and decreased the pressure on pump and the only thing this did was change the cycling from 30 seconds to about 60 seconds. What did I do wrong and/or missing. Any suggestion would be apppreciated, Thanks

When we had recurring cycling of the water pump it was because the tank fill valve was leaking. Pump would pressurize, slowly leak past tank fill valve until would cycle again (about every 30-60 seconds). Replaced tank fill valve-problem gone. Your mileage may vary.

If you also used the little tube to suck the pink antifreeze into the system, you shold check to see if the valve that goes to that hose in closed. I have a new to me coach and it was winterized by the dealer. They left the valve open. The water system was ok if I was on city water, but as soon as I tried using the water from the holding tank the pump kept cycling and water flow was sporatic at best. Im just saying..............

It could also be a leak somewhere in your water system like a leaking faucet.

I think the problem is fixed. The last thing I did was recycled the fill tank valve by the city water inlet. I normally do not use it to fill the water tank. I waited over 5 minutes and the pump has not recycled. Thanks for all the suggestions.
