Hot water leak in 2011 WP19
I just put my 2011 Wolf Pack Toy Hauler WP19 back in service after winter storage. The cold water system pressurized fine, with no leaks. After I reinstalled the plug in the bottom of the water heater and filled the hot water system, I had water running our from underneath the microwave and fridge area, and it was also leaking out onto the ground in the area under the fridge.. The leak stopped as soon as I depressurized the hot water system. So 2 questions for the experts:
1. Does the hot water line flow from the heater to the shower to the vanity sink, and then pass under the floor over to the kitchen sink? If so is there a place where I can temporarily cut the crossover line and install a shutoff valve so that I can use the shower and vanity sink. I am experienced with PEX and I have the proper fittings, crimper, and check gages.
2. How do I best gain access to repair the line? I am guessing a mouse chewed through it since it was properly winterized, plus we actually had a mouse chew through a CPVC line in the barn right next to the where the trailer was parked. There is no access to the leak from under the sink, so I am considering pulling the microwave or fridge to gain access. Alternately, can I gain access from under the trailer?
Anyhow, thanks for any advice.
