      The downside of the boating life can be maintenance chores. Pumping out boat waste is one of them. Installing the best quality marine deck fills and waste caps, however, can make this chore go as smoothly as possible. Wholesale Marine carries a selection of Marine Deck Fills and Waste Caps to fulfill your boat’s marine sanitation requirements. We carry brands you’ll recognize like Perko Marine, Sea Dog, Sealand, and Whitecap Industries.

      Wholesale offers pump-out adapters that make holding tank clean-outs as clean, easy, and fast as making a trip to the gas station. These units feature airtight seals between deck waste fittings and both the pump-out station nozzles and plastic adapters screw into deck fittings for a clean connection. Whitecap Industries’ Push-Up Stainless Steel Deck Fill-Waste is made from durable stainless steel for years of reliable use. Sea Dog offers another stainless steel option in their Waste Deck Fill 1-½”, which also includes an attached chain so the cap is not easily lost.
