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 cause by 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)

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.
