We were asked to investigate a rat infestation within a local school in the Swindon area, rats had been gaining access via sewer pipes and getting access to buildings.
We surveyed the sewer pipes and found rats had gnawed through two separate sewer chambers near the building and had dug through loose sand and gained access to the brick cavities.
This is a all two familiar story as with the introduction of plastic pipes and chambers used in new buildings we have seen a increase in rat related issues within these types of pipes.
Currently no resistant pipes are available against rats so replacing the effected pipe or installing a non return valve really is the only option.
Call us today or order your 110mm no return valve online to assist in prevention and control of rats.
