Re: Dump Valve Replacement
I recently replaced both black and grey valves, same size as yours, on my 1990 Leisure Van. A couple things come to mind.
1. Are you sure you are seating the valve properly? I had quite a bit of trouble seating the grey water valve because of limited "moveability" of the pipes and space to work. Took several tries but finally did get it in place just fine.
2. The upper corner of the tank side flange of the black water was broken. I managed to jury-rig it with a larger washer and a wooden 3/4 flange template and a longer bolt. I would not want to take the pipes off.
