Description
Competa CUG4GT Universal Gully Trap for 110mm Underground Drainage
The
Competa CUG4GT universal gully trap is a trapped fitting for compatible 110mm below-ground drainage installations. This
110mm universal gully trap provides a practical connection point between a suitable surface-level hopper or drainage inlet and the underground pipe system. Designed as an
underground drainage gully trap, the fitting maintains a trapped water seal while allowing waste water or surface water from an appropriate drainage arrangement to continue into the below-ground system. The compact
110mm gully trap fitting is suitable for repairs, extensions and new installations where a
universal underground drainage trap is required.
Competa CUG4GT Universal Gully Trap
The
Competa CUG4GT universal gully trap is designed to form the trapped section of a compatible underground drainage gully arrangement. Unlike a complete bottle gully with its own top grid, a universal trap can be combined with a suitable hopper or other compatible drainage components to create the required collection arrangement at ground level.
110mm Universal Gully Trap
The
110mm universal gully trap is intended for use with compatible nominal 110mm underground drainage pipework. Its trapped design allows water to pass into the drainage system while retaining a water seal within the fitting. This helps separate the open drainage point above from the below-ground drainage pipework. Always check the actual connection arrangement on the fitting and receiving pipework before installation so that all joints are compatible and correctly supported.
Underground Drainage Gully Trap
An
underground drainage gully trap is commonly used where suitable external waste water, rainwater or surface drainage needs to enter a below-ground gravity drainage system through a trapped connection. The trap should remain correctly installed and accessible through the associated hopper or gully arrangement so that the drainage point can be inspected and cleaned when required.

110mm Gully Trap Fitting
This
110mm gully trap fitting can form part of a complete external drainage arrangement when combined with the correct compatible inlet or hopper components. The universal format is useful where the required surface-level collection point is being built from separate drainage components rather than using a complete one-piece bottle gully.
Universal Underground Drainage Trap
A
universal underground drainage trap provides flexibility when creating a suitable external drainage point. Depending on the installation, a compatible hopper can be positioned above the trap to receive water before it continues into the underground drainage system. The chosen hopper, trap and onward drainage pipework should all be compatible with one another and correctly supported before surrounding paving, concrete or backfill is completed.
Why Use a Trapped Gully?
The retained water seal inside a gully trap helps separate the external drainage opening from the connected underground pipework. This makes trapped gullies useful for suitable external drainage installations where water needs to enter the drainage system through an accessible surface-level collection point. The trap should contain sufficient water during normal use to maintain its intended trapped function.
Typical Applications
The CUG4GT can be used within appropriate external drainage projects including:
- Patios
- Garden paving
- Yards
- External drainage points
- Suitable waste water discharge arrangements
- Rainwater drainage installations
- Domestic drainage projects
- Extensions and renovations
- Replacement underground drainage installations
Using a Universal Gully Trap with a Hopper
A compatible hopper can be used above the
Competa CUG4GT universal gully trap where an open collection point is required at the finished surface. The hopper receives incoming water and directs it towards the trapped section below. Choose the hopper shape and connection arrangement according to the surrounding paving, incoming pipework and available installation space. Always check compatibility between separate components before permanently assembling the drainage system.
Installing the 110mm Universal Gully Trap
Before installing the
110mm universal gully trap, establish the underground drainage route, finished ground level and required position of the hopper or inlet above. Provide firm support beneath and around the fitting so the connected pipework is not being used to carry the weight of the complete gully arrangement. Keep all drainage joints clean during installation and check that connecting pipes and fittings are properly aligned before completing the surrounding backfill.
Maintaining an Underground Drainage Gully Trap
Keep the associated hopper or access point clear so that the
underground drainage gully trap can continue to receive water freely. Leaves, soil, silt and other material should be removed before they build up and restrict the drainage route. Where maintenance access is available, periodically inspect the trap and connected pipework to help identify debris or restrictions before they develop into a blockage.
Universal Trap or Bottle Gully?
A
universal underground drainage trap is useful where the drainage point is being assembled using separate compatible trap and hopper components. A complete bottle gully may be more appropriate where a compact all-in-one trapped gully with an integral top grid is preferred. Choosing the correct arrangement depends on the required inlet position, available space and surrounding drainage layout.
