Installing a vented loop will ensure that fluids will not siphon from a tank or the sea. Vented loops are commonly used in the marine toilet system and engine cooling system.
\n
\nThe simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes
\nthrough. Molded in Marelon®, neither vent nor loop will corrode.

\nThe duckbill one way valve is designed to seal properly if particulate matter is present in fluids.
