Check the drainage before installation
A 4-inch booking must match the actual pipe and device requirements. Your technician checks accessible drainage, flow direction and the intended protection route. Do not choose a size solely by estimating the width of a chamber cover; the pipe itself needs assessment.
How a rat blocker works
A rodent-specific non-return device is designed to allow outward wastewater flow while restricting rats travelling back through the protected route. Correct positioning matters. A valve in the wrong branch may not protect the building, and other access routes may remain.
What supply and fit includes
The 4-inch supply-and-fit service covers the named supply-and-fit service in suitable accessible drainage. Drain clearing, excavation, structural repair, camera surveys and ongoing rodent treatment are separate unless agreed. Contact us before booking if access or pipe suitability is uncertain.
Maintenance and existing rats
The device needs to remain accessible for inspection and maintenance in line with its manufacturer’s guidance. Installation does not remove rats already inside the property. We can discuss investigation, control or proofing where the inspection suggests these are also needed.
Book the right service
Select the matching rat-blocker size in online booking. If you have recurring activity but do not know the entry route, start with a Rodent Investigation & Survey or ask about a drain CCTV survey. We will explain any limitations before proceeding.

4-inch Rat Blocker Installation Oxford: Before You Book
A 4-inch listing identifies the named service, but the drainage still needs assessment. Nominal pipe sizes and the space available in an inspection chamber do not establish that a particular device will fit or protect the intended route.
Tell ProPest whether the chamber is accessible and whether previous camera footage or repair information is available. The proposed position needs to account for the drainage layout and direction of flow. A suitable installation must also remain accessible for future checks.
If the route is uncertain, consider a drain CCTV survey or rodent investigation first. Compare the 6-inch service only after the correct requirements have been established. Physical exclusion is one part of our IPM prevention approach.
