How do I protect my drains from rats?

Keeping rats out of drains is essential for any domestic or commercial drainage system. Rats can often gain entry through damaged pipes or drains, and once in, could gain entry to your home or business. It is essential to ensure your drainage system is working properly and installed correctly to prevent any infestation or entry of rats.

Rats in Drains

In the UK, sewers are the ideal environment for rats to live, which is why it is important to protect yourself and your property from rodents. The drains of your properties connect to sewers that are teeming with the vermin, so ensuring your drains are in good working order is crucial to protecting yourself from disease-carrying pests. It is also important, depending on the type of drain used by your property, to have additional, specialised measures in place to prevent rat entrance.

Common signs of a rat infestation:

  • – Rat droppings found in the property
  • – Chewed paper, packaging, cables or plastic
  • – Small holes gnawed in walls
  • – Scratching noises in the walls, floors or roof

 

How do I protect my drains from rats?

Sealed Drainage

Ensuring your drainage is sealed is essential to protect your home or business from rats. Sealed drainage means there are no openings in the pipework between the discharge stack of the home or sewer. Although this does not protect the property from infiltration stemming from the sewer itself, as well as the protection it does offer to homes, it helps stop rats entering the sewer. This type of drainage will require regular access covers for inspection chambers and entry of rods to clear blockages. These should allow maintenance of the drainage pipes from the surface.

Rodent Barriers

Rodent barriers are installed within the pipes to prevent rodent entry to your drainage system, helping to protect your home.

This includes a variety of devices within the pipes such as:

  • – Downward facing fins in the discharge stack
  • – One way valves in the underground drainage
  • – Enlarged sections of the discharge stack to prevent rat climbing

 

Intercepting traps

Intercepting traps are a U-bend section of domestic sewer pipe made from fireclay. These are also known as the Buchan trap, disconnecting trap or Bristol interceptor. This U-bend is filled with water. Although this trap will prevent sewer smells from escaping the pipes, its worth in protecting against rodents is rather more dubious; they are often easily able to swim through an interceptor trap. Another downside of this type of protection is that it is easily blocked and will require frequent maintenance.

Thus, it is crucial that the trap is installed such that a rod can be easily inserted to remove blockages.

Covers & Gratings

Placement of plastic covers or metal gratings that allow the passage of waste but block rats should be placed within the pipes.

Cages

Metal cages are often placed in the ventilation pipes that stem from over the discharge stack, blocking that route for rat escape & entry.
