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. Call us if you have an
interceptor as rat barriers should not be fitted to rodding eye pipes,
these should be protected with a rodding eye cap or a drain plug which
we can supply.
