FloPlast Air Admittance Valve - Grey - 110mm

An AAV allows air into the sanitary drainage system to prevent negative pressure, which can cause slow draining, gurgling sounds, and allow foul gasses to escape.

The AAV should be installed vertically, above the flood level of the highest fixture in the system and in an accessible location for inspection and maintenance.

Clean the pipe and the AAV fitting, apply solvent cement, insert the pipe into the fitting, and allow the cement to cure. Always follow the manufacturer’s instructions.

Regularly inspect the AAV for blockages or debris. Clear any obstructions and check for a proper seal. Replace if damaged.
