Not sure how I would ever adjust a durso, a piece of hose in the air hole prevents salt creep, never had a noise issue, my drain went into the sump water with a tee and a 90 above the water to exhaust the air so very little air went into the sump so no salt creep (probably also what made it so quiet), I still had an emergency drain for peace of mind on each system but never needed it.
