A general question. Why would the pressure drop over 15+ hours in the water system after you shut the water pump: note that the water heater had not been used and is cold. Of course over the space of a number of hours the system retains pressure (water heater cold and hot as tested). However, starting with a cold water heater, after an overnight shut down the water pump kicks in to restore pressure. I have opened up as much as I can to look for leaks and have not seen any. Have not looked in the underbelly but have tapped it to see if some water might have accumulated. Nothing.
The water pump is a SHURFLO 4008-101-A65 New 3.0 GPM RV Water Pump Revolution, 12V
It has an internal pressure bypass.
My previous TT only cycled a bit as the water in the water tank cooled (there were no leaks). Of course it would not maintain system pressure indefinitely come to think of it, but I don't think the pump kicked in after 15 hours with a cold non-heated water tank (sold it so can't test that).
I might be reading too much into this but with the pex to braided line issues my previous TT was all pex I just wanted some opinions.
