Ok, we were doing dishes tonite and I usually keep the galley tank valve closed to use it to flush the slinky out. Well guess we been doing a lot of dishes and water backed up into the sink, tank full. Ok no problem, just go pull the handle and drain the tank. So outside I go and pull the handle but I also hear water dripping or better yet gushing out on the ground. On the far side of the trailer in the rear corner, which was the low side, water is running out from the black belly cover. The question is is the tank suppose to be sealed or is there an air baffle or what is going on here. I check under the sink and no water there so has to be around the tank.
