Description
Competa CUG4PT Low Back P Trap for 110mm Underground Drainage
The
Competa CUG4PT low back P trap is a trapped fitting designed for compatible below-ground drainage installations. This
110mm low back P trap provides a practical water-sealed connection between a suitable external drainage inlet or hopper arrangement and the underground drainage system. Designed as an
underground drainage P trap, the fitting allows water to continue into the drainage system while retaining a trapped water seal. The
110mm drainage P trap is particularly useful where a low-back configuration is required, providing a compact
low back drainage trap for suitable external drainage, repair and new installation projects.
Competa CUG4PT Low Back P Trap
The
Competa CUG4PT low back P trap forms the trapped section of a compatible drainage arrangement and is intended for use with nominal 110mm underground drainage pipework. Its low-back configuration can be useful where the layout requires a trapped fitting beneath or alongside a suitable hopper, gully or external drainage collection point.
110mm Low Back P Trap
The
110mm low back P trap is designed for use within compatible gravity drainage systems. Water passes through the fitting while a quantity remains within the trap to form a water seal. This trapped arrangement helps separate the external drainage opening from the connected below-ground drainage pipework.
Underground Drainage P Trap
An
underground drainage P trap is commonly used as part of an external drainage arrangement where suitable surface water or waste water needs to enter a below-ground system through a trapped connection. The exact hopper, gully or inlet arrangement used above the trap will depend on the installation and the other compatible components being fitted.

110mm Drainage P Trap
This
110mm drainage P trap can be incorporated into a compatible external drainage installation where a dedicated trapped fitting is required. The surrounding pipework should be correctly aligned and supported so the P-trap is not placed under unnecessary stress once the installation has been backfilled or finished.
Low Back Drainage Trap
The
low back drainage trap format provides a compact alternative where the position of the inlet and onward drainage route requires a lower-profile trapped connection. Before installation, check the available space, finished ground level and position of the connecting drainage pipework to make sure the fitting suits the intended layout.
Why Use a P-Trap?
A P-trap retains water within its curved section. This water forms a seal between the external drainage point and the underground drainage system. The trap should be installed in the correct orientation and remain connected to a suitable drainage arrangement so that its water seal can function as intended.
Typical Applications
The CUG4PT may be used as part of suitable external drainage arrangements around:
- Patios
- Yards
- Garden paving
- External drainage points
- Suitable waste water outlets
- Hopper drainage arrangements
- Domestic drainage installations
- Extensions and renovation projects
- Replacement underground drainage systems
Using an Underground Drainage P Trap with a Hopper
A suitable hopper can be installed as part of an arrangement using the
underground drainage P trap where an open surface-level collection point is required. The hopper collects incoming water before directing it through the trapped section and into the onward underground drainage system. Always check compatibility between the hopper, trap and connecting pipework before permanently assembling the installation.
Installing the 110mm Low Back P Trap
Plan the underground drainage route, finished surface level and inlet position before fitting the
110mm low back P trap. Provide suitable support beneath the fitting and connected pipework. All joints should be kept clean and correctly aligned during assembly. Once connected, check the drainage route and make sure water passes freely through the system before completing surrounding backfill or paving.
Maintaining a 110mm Drainage P Trap
The drainage inlet or hopper associated with the
110mm drainage P trap should remain accessible so leaves, silt and other debris can be removed when required. Keeping the inlet clear can reduce the amount of material entering the trap and help maintain unrestricted flow through the underground drainage system.
Low Back P Trap or Universal Gully Trap?
The CUG4PT
low back drainage trap is specifically a low-back P-trap fitting. The CUG4GT is a separate universal gully trap. The correct choice depends on the required drainage layout, available installation space and the compatible inlet or hopper arrangement being used. Check the connection requirements before ordering rather than assuming the two trap types are interchangeable.
