Black tube vent causing smell in bunk storage area 26bh
Hey all. I have a 2013 Sunset Trail 26BH, and underneath the bunk in the rear, the storage area, there is a black tube that I would guess is the drain from the shower. Off of that there is a vent pipe. From that vent pipe I'm getting a pretty nasty smell. Smells somewhat sulfurish and natural gasish.
Just started this season, but the past week or two when I've noticed it we have hit a couple of relatively high temps in the area.
I'm wondering if it's just the drain pipe for the shower and the smell is from is from the heat and expansion of gases, and maybe a good sanitizing of the grey tank is needed. I haven't done one in a couple of years.
Thanks for the input.
