? Leak ?

[Sully406]

Hey everyone- nubes here, we’ve got a 2021 High Country, only have had it a few weeks. Full timing it, we’ve got a leak that seems to come from nowhere. The floor and lower paneling along the wall edge and in the pantry area towards the stairs at the front end of our camper. We’ve pulled the panels off the wall on the inside of our pass through area and there is a few areas where there’s water, they’re in various spots, not connected at all, and seem to be from one side of the area to the other. We’ve looked at everything we can see from top to bottom and have not been able to find even a drip or wet area on any of the pipes or connections. ?? Has anyone had this issue ??
Model is a 350BH

Check the plastic moulding that runs full length of both sides. If it isn't sealed, water will wick in on your floor. The silicone the factory used is very low quality. Clean it off and use some Lexel or other quality sealer.

Make sure you are using an external water pressure regulator on your incoming freshwater line. You don't want more than 55psi to be safe.
Based on your Floorplan,

Your bathroom is behind the pantry wall.
Maybe, check the shower plumbing fittings while running water. Also check the shower drain in the basement while running water and have someone stand in the shower to provide weight on the floor fittings. My drain pipe leaked. Had to tighten the drain pan fitting. DO NOT OVER TIGHTEN.
Check behind the toilet while barely pressing the Flush pedal. My toilet (Thetford) has an anti-siphon valve behind there and it leaked when gently pressing the pedal. Not otherwise. You can replace the anti-siphon fitting,, Easy fix.
Next,
Under the sink you will see two white pipes going into a black plastic valve. This is the black tank flush system anti-siphon vacuum breaker valve. Notorious for failing. Run your black tank flush and watch for leaks coming from the valve. BTW this plastic valve is only rated for 65psi. Make sure you use a regulator on the hose.
It is best to replace this valve with a brass one. Available at Lowe's.
