What type/brand of hose should I use for the holding tank vent? The size of the fittings is 1/2 inch, which most sanitation hoses don't seem to come in. I want to find something that is not going to start smelling anytime soon. I am guessing the recommendation would be to have a bigger size vent in the first place, but I don't want to get into changing that at the moment.
Thanks!
