McAlpine sink/basin white reduction trap 3/2" x 5/4" HC54

McAlpine HC54 is a white reduction trap designed for sinks and basins with inlet and outlet diameters of 3/2" x 5/4". The trap adapts between different pipe sizes while providing an effective water seal to block sewer gases. Constructed for domestic kitchen and bathroom installations, this reduction trap is suitable where a compact size adaptor is required to join waste fittings of differing diameters.

Advantages

The reduction trap offers a reliable water seal to prevent unpleasant odors and ingress of sewer gases. Its white finish provides a neutral appearance that integrates with most sanitary fittings. The compact form factor simplifies installation in confined spaces beneath sinks and basins. The trap is compatible with standard waste fittings and helps maintain a secure mechanical connection between pipes of different diameters.

Suitable for

• Domestic kitchen sink installations where a size adapter is needed
• Bathroom basin waste connections with mismatched pipe diameters
• Replacement of existing traps to convert between 3/2" and 5/4" outlets
• Tight under-sink spaces requiring a compact trap body

Key specifications

• Material: durable white plastic suitable for sanitary waste systems
• Connection sizes: reduction between 3/2" inlet and 5/4" outlet
• Function: provides water seal to prevent sewer gas escape
• Finish: white color for neutral appearance under sinks
• Design: compact profile for installation in confined spaces

How to use

Install the reduction trap between the sink or basin tailpiece and the waste outlet by sliding the correct ends onto the corresponding pipe diameters and securing with the appropriate compression fittings or seals. Ensure the trap is aligned to maintain a continuous downward fall to the waste pipe and that all joints are tight to prevent leaks. After installation, run water to verify that the trap holds a water seal and that no leakage occurs at connections.

Usage recommendations

For reliable performance, check that mating fittings and seals are compatible with the specified inlet and outlet sizes. Periodically inspect the trap for blockages and clean as needed to maintain drainage performance. Avoid exposing the plastic to direct heat or aggressive chemicals that could degrade the material.
