After I took a shower this morning I went outside and noticed water leaking on the ground and it seemed to be coming from under the shower. I checked all the exterior water connections and they were dry. While the wife was showering, I watched from outside the rig and the water is dripping pretty steady from the underbelly protective cover so I imagine I have a leak somewhere around the shower drain.(there was no water leaking while the water was pressurized, only when the shower was operating) Before I remove the underbelly covers I was wondering if someone had a plumbing diagram for a 369RL. I would rather know what Im looking for before I start poking around. Thanks.
