Rat Flap Installation Harrow

Rat flaps (non-return valves) can help prevent rats travelling from the sewer into a property’s drainage system in Harrow. Correct selection and installation matters.

When a rat flap may help

  • Confirmed sewer-side activity
  • Suitable pipe runs and access points
  • After defects have been identified and addressed

We normally recommend CCTV evidence first. Start here: Rats in Drains Harrow.
