Re: Best hose for holding tank vent pipe?
At the least, I would use proper sanitation hose. When the boat heels, its not uncommon for some effluent to wash up into the vent hose.
Additionally, it's recommended that a vent line be at least 1". Air exchange is one of the key requirements to keep a tank from smelling badly. Odor is caused by anaerobic bacteria that only live in low Ox environments.
