When we have our water pump turned on I will randomly hear it pressurize. It happens about every few hours for a second or two. Could this mean a leak?
no if it was leaking you would know
Yes it can be a leak like a dripping faucet, it can also be caused by other issues. First check all faucets including outdoor wash-down showers. Check all piping under sinks, behind toilet etc. Other causes are a worn pump check valve that is allowing pressurized water to seep backwards through the pump into the fresh water tank or a leaking water tank fill valve. These last two causes while annoying are not detrimental to the structure of your RV.
