This is the 6 inch mdel of the RatFlap which is designed to prevent rats entering your drains from the main sewer.

  • Robust and long lasting
  • All Stainless Steel
  • Easy to fit in clay or plastic pipes

The Ratflap does what traditional rat-control interventions do not: it stops the rats before they enter your workplace or home and prevents them from ever becoming a problem.
Rat traps and pesticides are designed only to work after the rats have arrived, after they've dragged filth, germs and disease into your world. In contrast, the Ratflap prohibits rats from ever encroaching on your work or home life by denying rats in their major thoroughfare: your water pipes and sewer system.

How the RATFLAP works:
The Ratflap works 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 Ratflap fits snugly 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, we can advise on this.

In the datasheet tab there is a typical drain plan that will help locate where the ratflap will need to be installed, below is a link to installation guide.
