Rat Flaps & One Way Rat Valves
Rats entering properties through the drainage system is more common than most people realise. As authorised fitters, we install rat flaps and one-way rat valves that permanently block this entry route. without affecting drain flow.
What's Involved
CCTV Drain Survey
Before any valve is fitted we carry out a full CCTV survey of the drain run to assess the pipe condition, confirm the correct fitting point, and ensure the drain is structurally suitable for the installation.
Valve Selection & Sizing
We select the correct rat flap or one-way valve size and type for your drain. The valve allows waste water to flow freely outward while physically preventing any animal from travelling back up the pipe.
Professional Installation
The rat flap or valve is fitted by our authorised engineers at the correct location within the drain run. typically at the last manhole before the sewer connection. All fixings are checked and the seal confirmed.
Post-Installation Check
We run a final inspection to confirm the valve is operating correctly, the drain is flowing freely, and the installation is documented. You receive written confirmation of the work carried out.
Signs Rats Are Using Your Drains
- Rats appearing inside the property but no obvious entry point found during a standard inspection
- Gnaw marks around toilet pans, soil pipe connections, or under-floor waste pipes
- Evidence of rats in the garden but no structural entry points identified on the building
- Previous rodent treatments that resolved temporarily but keep recurring
- Neighbours in the same terrace or row experiencing the same recurring problem
- A CCTV drain survey that has already identified rat activity within the pipe system
Why Choose Us
Authorised Fitters
We are authorised installers of rat flaps and one-way rat valves. This matters. incorrectly fitted valves can restrict flow, cause blockages, or fail entirely. Authorised installation protects your warranty.
Pest & Drainage Expertise Combined
As both pest control specialists and drainage contractors, we understand how rats use drain systems to access properties. We assess the full picture. not just the drain in isolation.
Long-Term Solution
A properly fitted rat flap eliminates drain-based entry permanently. Combined with any above-ground proofing required, it provides the most complete and cost-effective long-term defence.
