FloPlast Air Admittance Valve - 40mm - White

An air admittance valve (AAV) allows air into the drain pipes to prevent negative pressure, preventing trap seal loss and drain odours.

Typically, install the AV40 in a waste tee cut into the main waste pipe run, above the flood level of the highest fixture in the system.

The AV40 is installed using compression fittings. Ensure a tight seal to prevent leaks. Follow the manufacturer's instructions for secure installation.

The AV40 is designed for use with most 40mm plastic waste systems and some copper waste pipes. Always check compatibility before installation.

Check the valve for any blockages or damage. Also, ensure that all connections are airtight, and inspect for other sources of the odour.

Regularly inspect the valve for any blockages or debris. Clean the valve if necessary to maintain proper function.

It means the valve meets European standards for air admittance valves, ensuring it performs correctly and meets safety requirements.

Check the valve for proper function. Ensure it is not blocked or damaged. Also, check for any leaks in your plumbing.

Verify the valve is installed correctly and allowing air to enter the system. Check for any obstructions in the waste pipes.

Inspect the waste pipes for blockages, and ensure the valve is allowing sufficient airflow.
