Welcome to the sewerstore and our range of 110mm non return valve rat drain flap.

If you are looking at this product it is likely you unfortunately have a rodent or flooding problem, luckily we can provide you with a cost effective solution using our rat drain flap non return valve.

Firstly we are a pest control company based in Swindon Wiltshire and have decided to develop our own range of non return valves as others on the market were simply not up-to the task. We have tried and tested our products in real situations and have resolved customer problems where other products have failed using our stainless steel rat drain flap




The main difference with our ratflap compared to others is that they are fully stainless steel apart from the rubber seal. Plastic versions of the rat blocker for drains on the market but they get damaged by rats causing them to fail, also on the market are steel flaps but they use internal hinges and in our opinion waste such as tissue paper etc can get caught on the hinge and potentially cause a blockage. Our rat drain tflap valves are welded using stainless weld and stainless hinge meaning there is nothing within the body for waste to foul on. Also no other stainless ratflap 110mm valves  are available for flooding defence.
