Product description

Our 110mm water and rodent non return valve guards against pests such as rats entering properties through the sewage system, and protect against the backflow of water and sewage into your property in times of flooding.

The non return valve has an inbuilt stainless steel plate on the flap and face to stop rodents biting through, providing efficient pest control. The one way flap valve allows the rat and rodent to leave the property, but stops them coming back up the rising main and into your toilet or house.

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.
