110mm Air Admittance Valve – The Professional Way to Prevent Trap Siphoning
The Air Admittance Valve 110mm (often referred to as a “Durgo” valve) is a critical component for modern internal plumbing. When large volumes of water travel down a soil stack, they create negative pressure that can suck the water out of your sink or toilet traps. This AAV prevents that “gurgling” sound and the subsequent release of smells by instantly equalising the pressure. At ECO Heat Shop, we supply the trade-grade hardware and ventilation fittings required to keep your waste system quiet and sanitary.
Versatile Design and Maintenance-Free Performance
Manufactured from high-impact PVC-u with a durable internal seal, this valve is designed for long-term reliability. It is an ideal solution for home extensions or loft conversions where running a pipe through the roof is impractical or aesthetically undesirable. The valve is typically installed at least 100mm above the highest flood level of the highest appliance connected to the stack. Its sleek, compact profile ensures it can be tucked away in vanity units or attic spaces while still providing full system ventilation.

ECO Heat Shop Tip: While AAVs are a fantastic space-saving tool, they must be installed in a ventilated area (like a loft) so they can “breathe.” Never box them in airtight. Choosing an Air Admittance Valve is a sustainable building choice; it reduces the number of holes in your roof membrane, significantly lowering the risk of future roof leaks and improving the overall thermal integrity of your home’s envelope.
