Installing a vented loop will ensure that fluids will not siphon from tank to tank. Forespar Marelon Vented Loops are commonly used in the marine toilet system and engine cooling system.
The 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 through.
Molded in Marelon, neither vent nor loop will corrode. The duckbill one-way valve is designed to seal properly if particulate matter is present in fluids. Marelon is the only synthetic material to pass the stringent Marine U.L. testing.
All critical hose connections should be double clamped at both ends. Ideally, the hose clamp screws should be mounted opposite one another for maximum security. Use the highest quality AWAB hose clamps for longest life and best performance.
