Wastewater Air Valve

A double Wastewater Air Valve is used to prevent excess pressure of gases and liquids, stop vacuums in the pipe system that can damage pipework in pumping system by allowing air into the system, then bleeds of gases as the system is pressured when the pumping restarts, maintaining stability.

Please see below our Working with Air Valves document and our Wastewater Air Valves datasheets under the Option Comparison tab.

Orders placed by 3-00 pm have same working day dispatch and prompt delivery, normally next working day delivery, on selected models only.

Currently we are experiencing issues in achieving next working day delivery in some areas due to HGV driver shortages.
