My fresh water pump has recently started cycling when no water is being used. It's most noiceable when sleeping. Probably about every 15-20 minutes it will run for a couple seconds. I see no signs of leaks anywhere. I'm thinking it's the pump itself maybe losing pressure through the check valve or something like that. For troubleshooting, I'm thinking if I pressurize the system then turn off the valve at the entry to the water pump, that may prevent it from losing pressure. If it doesn't turn on for an hour, it would indicate the pump being the problem. Any thoughts? Anyone have a similar issue?
