Yes and I am thinking gas will move faster than water so I would be looking at 1" or 3/4" if absolutely necessary. Maybe 1/2" but that has a much greater chance of creating issues. I assume code is 1.5".
Yes.
Air flows easier than water, so pipes do not need to match. I don't plan on putting water in the tank (shower, sink, flush) fast, just to drain it out fast.
My tank is over 1/4 inch thick at vent (black outer layer and white, smoother, inner layer), would this grommet fit? It looks to be made for a thinner wall.
the grommet sounds perfect, except I absolutely can never, ever have a leak on the camper floor. I just spent a month cutting out the fiberglass floor, pulling out soggy wood and installing new floor and new fiberglass patches. The grommet would stick through the floor or not? If I put that one in link upsidedown it might work. I never fill tanks, so not worried about an inch loss.
