Forespar Marelon MF Vented Loops

If your toilet is below the waterline, vented loops should be installed in both of the lines.

Installing one of Forespar's four different size diameter Vented Loops will ensure that fluids will not siphon from tank to tank or the toilet.

A Vented Loop is commonly used in the marine toilet system or an 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 it.

Moulded in Marelon ®, neither the vent nor the loop will corrode.

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