An essential safety component on all inlet and discharge plumbing of toilets installed below the static or heeled waterline.

• Simple valve system ensures water cannot siphon over plumbing loops.
• Available in three sizes for 11⁄2” (38 mm), 1” (25 mm) and 3⁄4” (19 mm) ID hose.
• Internal valve avoids need for external venting.
• Molded in tough, corrosion proof plastic.

Tru-Designs vented loop has been designed and manufactured in New Zealand for use in marine applications. 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 siphoning 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.
