Trap siphon McAlpine HC4PF-32 5/4" DN32 white for basin/drain

McAlpine HC4PF-32 is a 5/4" (DN32) trap siphon in white finish designed for basin and drain installations. It provides a sealed water trap that prevents sewer gases from entering indoor spaces while maintaining a standard 5/4"/DN32 waste connection used in many domestic plumbing systems. The compact design fits under sinks and basins where space is limited and is suitable as a direct replacement for compatible traps with the same connection size.

Advantages

The trap siphon is manufactured to provide a reliable water seal while being easy to install and maintain. Its white finish integrates discreetly with typical basin fittings. The product offers corrosion-resistant performance for standard household use and a straightforward removable design for cleaning or clearing blockages without the need to dismantle surrounding pipework.

Suitable for

• Domestic washbasins and bathroom basins
• Under-sink installations in kitchens with DN32 waste outlets
• Replacement of existing traps with 5/4" (DN32) connections
• Compact plumbing installations with limited under-basin space

Key specifications

• Connection size: 5/4" (DN32)
• Colour/finish: white
• Application: basin/drain trap siphon
• Seal type: water trap to prevent sewer gases
• Design: compact under-sink fit, removable for cleaning

How to use

Position the trap siphon between the basin outlet and the waste pipe, ensuring the 5/4" (DN32) connections align with the existing fittings. Hand-tighten the connections and then use appropriate tools to secure a leak-free joint, taking care not to overtighten plastic components. Fill the basin with water and check the trap for leaks; if present, re-seat seals and retighten as required. Periodically remove the trap body to clear debris and inspect the seal to maintain an effective water barrier.

Usage recommendations

Use the siphon for typical household drainage where a DN32 connection is specified. Avoid exposure to aggressive chemicals or temperatures beyond normal domestic hot water limits. For persistent leaks or damage, replace the unit with a compatible trap siphon matching the same connection size.
