Drain Rat Blockers Fitted in Hazlemere (HP15)
If rats keep reappearing after traps and bait, the entry route is usually the pipework. Our Hazlemere technicians install stainless non-return valves—often called rat blockers or flaps—so waste flows out as normal but rodents can’t travel back up the line.
For full elimination indoors, pair this with our Professional Rat Control Service.
Why Drains Are the Weak Link
Rats use the public sewer, then pop into private pipework through defects, branch connections or redundant lines. Tell-tale signs include night activity near bathrooms or kitchens, repeat infestations after “clears”, and droppings around boxed-in pipe runs.
What We Fit (and Where)
- High-grade stainless steel single- or twin-gate valves for 100–150mm pipes
- Suitable for clay, uPVC and cast iron laterals
- Installed in the correct flow direction at the manhole or branch to protect your property without affecting neighbours
Survey First or Straight to Fitting?
Simple, well-mapped systems can go straight to install. If the layout is unknown, there’s a history of blockages, or multiple properties share the run, we’ll complete a drain trace/CCTV survey first. That confirms flow, finds breaks and ensures we place the valve in the right line.
Our Fitting Process
- Access & safety: Lift manhole/rodding point and isolate the work area.
- Confirm flow: Dye test or quick camera check where needed.
- Size & set: Select valve type, torque to spec and lock in position.
- Prove & document: Flush test, photograph the install and provide a short report with aftercare tips.
Pricing, Warranty & Maintenance
After an initial assessment you’ll get a fixed price for supply and installation (and CCTV if required). Valves and workmanship are covered by our warranty. Annual checks are optional but recommended if you’re on a shared line or prone to silt build-up.
Make It a Permanent Fix
A blocker stops new ingress from the sewer. We’ll also advise on sealing internal gnaw points, upgrading vent covers and tidying redundant penetrations so you’re not fighting the same battle again. If you’re currently hearing activity, combine this with our Control Programme for a complete solution.

FAQs
Will a rat blocker affect my drainage?
No—installed correctly, it allows normal flow out while preventing inward movement. We flush-test every install.
Do I always need a CCTV survey?
Not always. It’s essential when the layout is unclear or there are signs of pipe damage. Otherwise we can fit directly from the manhole.
Can you protect terraced or shared systems?
Yes. We position the device to protect your branch without obstructing the shared run and document the placement.
How quickly does the problem stop?
New ingress from the sewer stops immediately. If rats are already inside, we’ll remove them and proof internally as part of a plan.
What if the camera finds a broken pipe?
We’ll show you the footage and propose repairs. In many cases we can still protect your property with a blocker while the defect is scheduled.
