You might be able to rule out leak in plumbing by disconnecting shore power and using internal water -- if water pump periodically turns on when the taps are closed then you have a leak in the FW plumbing system.

Yes, it is time to engage your semi automatic "leak detection system". :B Disconnect from city water and turn on the pump.

BTW, the toilet water valve is one of the weakest links IF you have subjected your unit to freezing temperatures without winterizing.
