The dual flap sewer valve provides added protection against rat entering your property via the sewer network.
The valves are based on the same design as our single flap versions and are made using the same 316L stainless steel.
The Rat Drain Flap does what traditional rat control treatments such as baiting etc does not do. It stops rats before they enter your workplace or home and prevents them from ever becoming a problem. Rodenticides are designed only to work after the rats have arrived after they’ve dragged filth, germs and disease into the property. Our Non Return Valves prohibits rats from entering your work or home life by preventing rats accessing your water pipes and sewer system.
How the Sewerstore Dual Rat Drain Flaps work
The our sewer flap works is by blocking off sewage pipe access to rats from the outside while still permitting the free flow of water and waste from the inside.
The drain flap fits perfectly into your water or sewer pipe. Its steel flap opens when fluids need to flow freely into the sewer, but until then, the flap remains closed and prohibits rodents from entering. Quite simply, fluid flows out, but rats can’t get in.The unit can be fitted in either the outlet pipe from your home or in the pipe between your home system and the main road sewer. If your home was built before 1960 the chances are that you will have an interceptor fitted on the pipe from your home to the main sewer and in this case, you may only need a drain plug to solve your rat problem. If you have a interceptor then the valves need to be fitted to the outlets before the interceptor
