Non-return valve

Designed to eliminate the risk of flood damage by the backflow of sewage into properties through low level entries such as low level drain gullies, toilets and washing machine outlets. The Environment Agency in their publication on damage limitation for properties at risk from flooding and the Government guidance note “Preparing for Floods” both recommend the installation of non-return valves (anti-flooding devices) on all drains and sewers.

With a socket at one end and a pipe spigot at the other, these valves feature a flap which opens when foul water flows out, but remains shut should any water try to flow back. Can also be locked shut.

Available for 110mm and 160mm pipework.
