Trap syphon McAlpine HC2-J – plumbing sink/basin trap, plastic construction, compact design

McAlpine HC2-J is a compact sink/basin trap designed for domestic plumbing installations. Constructed from durable plastic, this syphon connects to standard sink outlets and provides a reliable water seal to prevent sewer gases from entering interior spaces. Its low-profile design makes it suitable for installations where space is limited beneath washbasins or small sinks while maintaining effective drainage performance.

Advantages

The plastic construction offers resistance to corrosion and routine household chemicals, while keeping the unit lightweight and easy to handle during installation. The compact form factor reduces the required under-sink clearance without compromising the trap’s sealing function. The components are designed for straightforward assembly and alignment with common sink outlet sizes, simplifying maintenance and replacement when needed.

Suitable for

• Domestic washbasins and small kitchen or utility sinks
• Compact or shallow vanity units where under-sink space is limited
• Renovation projects requiring a straightforward trap replacement

Key specifications

• Material: durable plastic suitable for household drainage use
• Design: compact, low-profile syphon for limited-clearance installations
• Function: provides a water seal to block sewer gases and enable drainage

How to use

Fit the McAlpine HC2-J trap to the sink outlet following the sink manufacturer’s instructions and local plumbing codes. Ensure all connections are aligned and hand-tighten the threaded fittings before applying final adjustment. Fill the trap with water to establish the seal and check for leaks by running water through the sink. If necessary, tighten connections gradually and recheck until the installation is watertight. For maintenance, remove and clean the trap components to clear debris, then reassemble and confirm the seal.

Usage recommendations

Install the trap in accordance with applicable plumbing regulations and use appropriate sealing materials on threaded joints if required. Avoid exposing the plastic body to open flame or high-temperature sources; clean with non-abrasive, mild detergents. Periodically inspect the trap for blockages and ensure the water seal is maintained to prevent odors.
