I am experiencing occasional leaking of grey water, I believe, at the drain conection. This occurs at certain ways I have the leveling jacks deployed. It seems that a minor twist of the chassis is causing the drain pipe to seperate just enough to allow a constant drip of approximately a bucket a day. I tried enlarging the metal wall of the compartment where the pipe comes out thinking that was where the movement might be occuring, but it did not help. I cannot see how to access the area where the drain pipe attaches to the tank from under the rig. Any suggestions are welcome.
