Product description

These PVC-U backflow preventers are non return valves with ring seal x spigot connections, the valves feature a handle for manual closing of the internal flap.

A backflow preventer can safeguard against contamination of water supplies and flooding caused by the backflow of waste water or effluent that occurs after a drop in pressure of mains supplies.

These non return valves operate automatically with no external power supply, the force of gravity in no-flow situations closes the internal flap preventing the backflow of water or effluent.

Backflow preventers are also known as backwater valves, drainage non-return valves and anti-flood valves.

AES and Simon have been consistently excellent – both in terms of the products they’ve supplied and the service during and after fulfilment. They’re all also genuinely nice people and I strongly recommend them.

Fantastic support before, during and after our purchase. Simon was very helpful recommended what we needed for our current setup, and even after when we were having a few teething issues he was always on hand to assist.

Helpful and informed

Graham Chester (verified purchase)

Nick was very helpful in sorting out a query we had about a pool bypass kit and how to install the kit. Sent us a diagram by email following a useful telephone conversation. We have now installed a bypass kit and are delighted it’s fully working. Thank you for your help.

Great Service

Paul Thompson (verified purchase)

Great service from the outset. Communication was spot on, and the engineers that attended were informative and pleasant. Can't fault anything from start to finish.
