Plumbing systems below the waterline need to consider adding a marine vented loop to prevent the back siphoning of sea water. Vented loops – also referred to as anti-siphon valves – prevent the siphoning of water by allowing air to enter when the line is not in use and sealing as water or other fluids pass by. Fisheries Supply is your premier supplier of marine vented loop anti-siphon valves from the top brands – so shop now and save or browse our extensive selection of marine plumbing fittings to complete your installation.
