need plumbing diagram

[JR51]

Have a leak when plugged into city water and when using fw pump. Based on where the most water is I have a general idea where it is. Plumbing schematic not included in my manual. Called mfr for help and no help offered for older rvs. I have a 1996 Tioga Montera. Before tearing up my floor Id like to see what I'm getting into. Leak is not from sinks, shower, fridge or hwh. The bulk of it is coming out of a drain hose under coach but floor is soaking wet under pantry drawer. Any and all help appreciated

you might have found the problem fill hot water tank then shut off vales leading out of the tank mine are under the sink area behind the tank leave city pressure on. now turn city pressure off wait a day see if water pressure dropped. I opened my safety valve to see if the water dropped .

Maybe too much city pressure, try a pressure reducer with a gauge. Older rigs probably have grey pex plumbing and are subject to leaking if too much pressure. They don’t like more than about 40 psi as far as I know.
