Gully Trap

1 min read Updated 6 Jul 2026 DrainSpy Brisbane
In short A water-sealed fitting that collects wastewater from external pipes or fixtures and directs it into the sewer drain while blocking odours with its water seal.

A gully trap is a below-ground fitting with a water seal that receives discharge — often from a laundry, kitchen waste or downstream of fixtures — and carries it into the sanitary drain. The water sitting in the trap stops sewer gases escaping to the surface.

Many gullies also double as the overflow relief point for the property, which is why keeping them clear and at the correct level matters.

What Is It For?

Collects wastewater at ground level and seals sewer odours out of the yard.

Where You'll Find It

Outside walls near laundries, kitchens and bathrooms, finished with a grated surface cap.

Common Problems

  • Leaf litter and soil washing in through the grate
  • Traps drying out in unused areas and letting smells escape
  • Cracked older earthenware gullies leaking and attracting roots

How DrainSpy Brisbane Deals With It

A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
