Rat Flap for Drains – DKG Pest Control Ltd are the RatWall drain valve Approved Installer Berkshire & Hampshire.
We install hundreds of Rat Flap units in drains each year, Dean has installed another two today!
One was very tricky to install in the right place and require part of the kitchen floor to be broken up as the internal manhole lid had corroded so badly the lid couldn’t be removed!
