I have a Coachmen 2018 Prism with the same problem. The is a knob in the back wall of the bedroom and it says, "Low Drain Point". Can't seem to find any info in the owner's manuals.
I see water dripping out just below this knob outside and at the bottom of the coach. It is coming out of a pipe. When I run the water it increases, so, might be the drain is slightly opened on the gray tank. However, can't budge the knob. Will try so WD-30.
Any one else has ideas please advise. Thanks in advance.
The low drain is to empty your fresh water holding tank, not much more info needed. Sounds like it's not completely closed, not sure why you think the gray water valve has anything to do with it. They are cheap little valves with small knobs. I replaced mine with a ball valve that has a larger handle. Depending on how it's plumbed it might be getting pressure from the line when you run water and that why it drips faster. My advice is replace the valve.
