What is the Ratflap®?

The Ratflap® is an ideal solution against rats entering properties via the drain system. The non-return valve is simply pushed into the pipework and does not require any specialist expertise or fitting equipment. Once fitted, the chemical resistant stainless steel valve let rats leave your property but they cannot get access back. The Ratflap® has been invented and patented by an Irish pest controller, and is now sold worldwide. Ratflaps® are manufactured from high quality acid resistant 304 grade stainless steel. The smooth design provides no resistance to the flow of waste. It is the only rat blocker system that allows 98.5% of the volume of the pipe to be utilised for waste flow .

Benefits of the Ratflap®

The Ratflap® provides these unique advantages:
  1. An immediate solution to rat infestations under floor boards, in walls or attic, as rats do return to the sewer for getting food (usually every day).
  2. Eliminating the expenses or delays of investigative work, e.g.: drain CCTV surveys, lifting floor boards, removing plasterboards, etc.
  3. Prevent the dilemma of killing rats by poisoning, which can leave dead bodies in the building structure and terrible smells that go on for weeks.

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 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

Terraced houses: Each house of the block usually need one Ratflap®:

Semi-detached houses: Two Ratflaps® are usually needed (one for each half of the building)

Apartment block: As many drain pipes come out of the building (sometimes over a hundred), the most cost effective way is to use tracing dye and draw a map of the waste water flow. As little as one 9″ Ratflap® may be sufficient if the main manhole (at the start of the line) can be identified.

  2. Excellent well made product. I could find no trace of rats round the house, no burrows or greasy marks on the walls round the exterior of the house, but there was a rat infestation in the loft, so I fitted one of these (well made) in the last WAV on the waste system. Presto, no more rats…
