Vented loops are commonly used for inlet and discharge pipes on toilet installations below the water line. Our Aquavent is moulded in a glass reinforced nylon composite, with a silicon bleed valve. The bleed valve allows air into the system to stop syphoning yet seals effectively when water or fluid pass through.
The advantage with our vented loops over others, is that the internal diameter is the same throughout the bend - meaning there is no restriction.
The Aquavent can be used as a holding tank vent by replacing the bleed valve fitting with a tube that is connected to a deck level vent.
