CCTV Drain Survey for Rats in London: What You Need to Know
Many London rat infestations originate from the sewer system. A CCTV drain survey identifies exactly how rats are entering your property.
Why Rats Enter London Properties via Drains
London's Victorian sewer system is ageing and extensively cracked. Rats are excellent swimmers and can travel significant distances through the sewer network. They enter properties through:
- Broken or cracked drain pipes — common in older London properties
- Unsealed pipe joints — gaps between pipe sections
- Damaged inspection chambers — broken or missing covers
- Toilet connections — rats can swim up through the U-bend of a toilet
What is a CCTV Drain Survey?
A CCTV drain survey involves inserting a small camera into your drain system to inspect the condition of pipes and identify:
- Cracks, collapses, and root intrusion
- Rat entry points and evidence of rat activity
- Blockages and build-up
- Structural defects requiring repair
The survey produces a full video report with recommendations.
Manhole Flap Valve Installation
A rat flap (or non-return valve) is a one-way valve installed in the drain system that allows waste water to flow out but prevents rats from swimming back up. This is one of the most effective long-term solutions for properties with recurring rat problems.
Manhole flap valve installation from £150.
When to Request a CCTV Drain Survey
