Drain Rat Protection

Stop rats entering your home through the drains. We install certified stainless steel rat blockers (non-return valves) to protect your property.

The No.1 Entry Point for Rats

Did you know that over 50% of rat infestations in UK homes originate from the drainage system? Rats are excellent swimmers and can navigate through sewers, U-bends, and breached pipes to enter your wall cavities or underfloor spaces.

Pest control poisons only treat the symptom. We solve the root causeby physically preventing rats from entering your property's drainage system while allowing waste to leave freely.

The Solution: Rat Blockers

A Rat Blocker (or non-return valve) is a stainless steel device fitted into your inspection chamber. It features a one-way flap that:

  • Opens to let waste water flow OUT
  • Locks shut to stop rats coming IN
  • Cannot be chewed through (316 Marine Grade Steel)
How a rat blocker works

Our 3-Step Protection Plan

1. CCTV Survey

We inspect the drains to find entry points, breaches, or nesting areas. Confirms if the infestation is active in the drains.

2. Valve Installation

We install the correct size non-return valve into the downstream manhole, instantly securing the property.

3. Internal Repair

If rats have chewed through pipes under your floor, we can patch repair them from the inside to seal off the wall cavity.

Common questions

How do rats get in through drainage?
Through defects: a cracked pipe, an open or disused connection, or a broken inspection chamber. The drain becomes a route from the sewer into the property or the garden.
How do you stop them rather than just remove them?
By finding and fixing the defect. A camera survey locates the entry point, the pipe is repaired, and where appropriate a non-return valve is fitted. Baiting alone leaves the route open for the next rat.
Do you work with pest controllers?
Often. Pest control deals with the infestation, drainage deals with the way in, and the problem only stays solved when both are done.
