Serving Stratford-upon-Avon & Surrounding Areas

Persistent rat activity is often linked to faults within underground drainage systems — issues that cannot be seen without specialist equipment. At Joe Day Pest Control, we combine professional pest expertise with advanced drainage technology to locate the exact rodent entry point and put permanent measures in place to stop infestations from recurring.

Our Drainage CCTV Inspection Service is designed for both domestic and commercial clients and is carried out by fully trained technicians experienced in drain-based rodent ingress.

Why Are CCTV Drain Inspections Important in Rat Control?

Many ongoing rodent infestations originate below ground. Even once surface-level entry points are sealed, rats can still enter through:
  • Cracked or collapsed drainage pipes
  • Redundant or disused drains still connected to the main sewer
  • Gaps around joints and connectors
  • Defective or deteriorating manhole chambers
  • Displaced seals or cracked clay piping
  • Damage caused by roots or ground movement
Rats will exploit even the smallest structural weakness. A CCTV drain inspection allows us to see precisely what is occurring inside your drains, helping us identify the true entry route and recommend the correct long-term solution.

What Our Drainage CCTV Inspection Includes

1. Initial Assessment

We begin by discussing the history of the rodent activity — noises, sightings, previous treatments, and any past repair work. This gives us crucial clues about where rodents may be entering before we begin the drain inspection.

2. High-Resolution CCTV Camera Inspection

We use specialist waterproof cameras to inspect internally through:

  • Main drain lines
  • Branch connections
  • Manhole chambers
  • Soil vent pipe connections
  • External drainage points
  • Internal waste exit points from kitchens, bathrooms, and utility areas

All findings are captured via high-definition video, enabling us to identify any structural defects or evidence of rodent movement.

3. Identification of Rodent Access Points

During the inspection, we look for:

  • Cracked pipework enabling rats to burrow into sub-floor spaces
  • Redundant or open drainage branches leading into cavities
  • Missing, damaged, or absent vermin protection
  • Internal breaks within manholes
  • Faulty clay or pitch fibre pipework
  • Points where rats are entering shared sewer networks

This process allows us to determine exactly how rats are reaching your property and what is required to stop further ingress.

Rat Flap / Non-Return Valve Installation (4" & 6")

After identifying the issue, the most effective preventative solution is often the installation of a non-return valve (rat flap). These devices sit within the drain line or manhole and act as a one-way gate:

  • Wastewater flows out normally
  • Rats are prevented from travelling back up the pipe and entering the property

Available Sizes

We supply and install:

  • 4" (100mm) rat flaps — commonly used in residential properties
  • 6" (150mm) rat flaps — ideal for commercial premises or larger drainage systems

Why Install a Rat Flap?

  • Provides instant, reliable rat ingress prevention
  • Works continuously with no maintenance required
  • Long-lasting stainless-steel construction
  • Compatible with the majority of UK drainage systems
  • Suitable for both domestic and commercial properties

Typical Installation Areas

  • Manholes
  • Outflow pipes
  • Drainage branches
  • External inspection points
  • Beneath toilets or waste stacks

Before installation, we ensure the correct size and positioning for optimal performance and unrestricted flow.
