[Fulltiming]

Hopefully the water leak is something simple, like a loose water line. Try wiggling the valve and see if you hear a leak on that tire. If those are not tightened properly when installed or the rubber seal ages, you can get a slow leak that drives you crazy. Easy to fix with a new valve stem IF you have a 1" pneumatic impact wrench, the appropriate jacks and some big guys to move the tire/wheel combination around, break the bead on the tire and then have adequate air flow to reseat the tire. I have gone through that on two tires.
