Purchase a 110mm Solvent Weld Air Admittance Valve Cheap From EasyMerchant
An extremely durable air admittance valve, also known as a durgo valve, is vital for your pipework system, allowing water to enter your system in order to balance the pressure and prevent any water trap siphonage if negative pressure develops in your pipework, bringing in clean air while preventing foul gasses from escaping into your bathroom via a one way system. You must install your solvent weld valve on a soil pipe at least 200mm above the highest water entry point on a system – this tends to be the highest point that water can reach within a soil pipe. Valves are typically installed within a cupboard or loft area, primarily for aesthetic purposes.
How Does A Solvent Weld Air Admittance Valve Differ From A Push Fit Valve In Terms Of Installation?
This is the solvent weld soil version – the only difference between this one and the push fit air admittance valve is that this one fits over the top of the pipe and is glued using solvent cement, creating secure solvent weld jointing. The push fit one uses a rubber inset to fit inside the soil pipe, similar to the joint on a WC pan connector.
In days gone by, vent pipes that were connected to the drain and opened to the atmosphere were used instead, as these would drawn in air to balance out the negative pressure in the system. However, due to regulations preventing open drains from finishing close to any opening window, these vent pipes had to be installed far above the eaves, resulting in both health and safety problems and an unsightly appearance.
