My gray water tank won't drain. While washing dishes this morning the sink started filling up. I thought at first that I had left the dump valve closed but when I went to open it it was already open...
Vinny did not tell us if this is new to him camper or if he has been draining the tank in the past with no problem :h
my shower and bath sink grey tank and the black tank handles are to the left of the dump tube and the sink dump valve is located to the right of the dump tube.
