I have a 1990 Champion Eurocoach 35′ (Oshkosh Chassis) While hooked up to city water, plumbing exploded under the kitchen sink floor. There is no water leak whatsoever under sink or at floor. It is under the floor and hidden in the underneath chassis, covered by foam spray insulation. After I heard a loud burst, water pours underneath rig as long as water is turned on. If I had a plumbing schematic, I could trouble shoot the location before I start attempting to remove the insulation, if I have to? Thanks in advance. John in Costa Mesa California. p.s. I now understand water pressure
The schematic is in the head of the “technician” that piped the trailer. Your best bet is to access the piping where the leak appeared and work from there to where the leak occurred. Even with a schematic, you would not know where in the pipe the rupture occurred.
