Floplast Black Solvent Air Admittance Valve – Black

The Floplast Black Solvent Air Admittance Valve is designed to allow air into 110mm soil stacks while preventing foul odours from escaping, maintaining balanced pressure within your drainage system. Ideal for use where traditional roof venting isn’t practical, this valve provides an effective solution for internal soil venting. Compatible with solvent weld systems, it creates a secure and permanent seal when fitted with solvent cement. The valve opens under negative pressure to admit air and closes tightly to stop gases from venting, helping to maintain hygiene and system performance. It’s a reliable choice for modern plumbing setups.
