P-trap 1 1/4 with waste, TYCNER 718 – plumbing trap for washbasin drainage

TYCNER P-trap 1 1/4 with waste (model 718) is a plumbing trap designed for washbasin drainage. The unit comprises a P-shaped trap body and an integrated waste connection that creates a reliable water seal to prevent sewer gases from entering interior spaces. Intended for installations that require a 1 1/4" connection size, this trap accommodates standard washbasin outlet pipes and provides a compact solution for under-sink drainage where space is limited.

Advantages

The P-trap design ensures effective retention of a water seal and minimizes odour penetration from plumbing systems. The integrated waste connection simplifies installation by aligning inlet and outlet paths, reducing the number of separate fittings required. Constructed for compatibility with common washbasin outlet dimensions, the trap offers a straightforward, low-profile layout that fits typical bathroom cabinets and pedestal sinks.

Suitable for

• Domestic washbasin drainage in bathrooms and lavatories
• Small commercial washbasin installations such as office or retail restrooms
• Replacement of existing 1 1/4" traps in renovation projects
• Compact sink fittings where space under the basin is limited

Key specifications

• Connection size: 1 1/4" inlet/outlet for standard washbasin pipes
• Design: P-shaped trap body with integrated waste outlet
• Function: Provides water seal to prevent sewer gas entry and retains trap water
• Installation type: Under-sink trap for washbasins and sinks
• Form factor: Low-profile compact trap suitable for confined spaces

How to use

Position the trap beneath the washbasin outlet so the inlet aligns with the basin tailpiece and the outlet connects to the soil or waste pipe. Ensure sealing washers or slip joints are fitted as required and tighten connections to prevent leaks. After installation, run water to fill the trap and verify there are no leaks and that the water seal is maintained. Periodically inspect the trap for blockages and clean the trap body or waste connection if slow drainage occurs.

Usage recommendations

Use appropriate sealing materials and do not overtighten plastic fittings to avoid deformation. For installations with limited access, consider using flexible connectors that match the 1 1/4" connection while maintaining correct fall to the waste pipe. Regularly flush the trap with water to maintain the water seal in seldom-used sinks.
