Designed by a pest controller who understands the biology and behaviour of brown rats, the RATFLAP® is designed to stop rats in their tracks, while not affecting the flow of the sewer. Made entirely from 304 grade stainless steel and precision cut by laser meaning RATFLAP® will last for decades. Taking years of development the device is designed to be a simple “fit & forget” solution and can be fitted by almost anyone although a basic knowledge of sewer flow and layout is recommended.
RATFLAP® is designed as a solution to stop rats gaining access to your drains without the need for laying poisons or traps meaning it is an environmentally friendly option. How it works is simple but highly effective.
If you hear rats in the walls, ceilings, or attic of your home, they most likely come from the sewer underneath the house. The best way to control rats on the long term is to fit a Ratflap® non-return valve to your drains pipes. Once fitted, the chemical resistant stainless steel valve let rats leave your property at night to feed they cannot get access back.
WHERE to Fit a Ratflap®?
If you have several toilets in your house you may have a few drain pipes converging onto a main one. If possible, locate the LAST manhole / inspection chamber on the sewer/septic that services your property. This way you will only need one Ratflap® only instead of one in each manhole.
These are the main scenarios below:
Detached house: Usually only one Ratflap® needs to be installed
Semi-detached houses: Two Ratflaps® are usually needed (one for each half of the building)
Terraced houses: Each house of the block usually need one Ratflap®:
