Leak under my fifth wheel RV

Question

I just recently bought a 2006 montana 5th wheel and I noticed I had horrible water pressure. The water filter was brand new and clean but the water regulator on it was clogged. The water pressure from the hose by itself was good but not enough to burst a pipe so, i took off the regulator. A few hours later, I have a leak under my RV on the passenger side. Im not sure where it's coming from. Any ideas?

I am not aware of any water lines on the passenger side of the trailer.

Could it be your fresh water tank over flowing??  Caused by leaking water pump check valve.

Apparently the water pressure WAS high enough to make something leak. I keep a pressure gauge handy to measure before connecting without a regulator.

I always use a pressure regulator.Even if you measure the pressure and it is OK during the day during at night when no one is using water I have found in some RV courts the pressure can get into the 100 psi range.  Most notably in Yuma Arizona.
