Washing machine siphon McAlpine WMV2-32PL over-surface white with trap ball

The McAlpine WMV2-32PL washing machine siphon in white is an over-surface outlet fitting designed to connect washing machines to household waste pipes where concealed installations are not available. The unit integrates an anti-syphon/anti-odour trap ball to prevent sewer gases entering the room and provides a compact drainage solution suitable for laundries, utility rooms and retrofit applications. Its smooth external finish and straightforward connection points simplify installation and maintenance while keeping the waste outlet accessible.

Advantages

The over-surface design allows installation without opening walls, reducing labour and modification of existing finishes. The integrated trap ball offers continuous odour protection and reduces the risk of siphoning from connected appliances. Constructed for reliable drainage, the siphon provides a neat visible solution that combines ease of access with a corrosion-resistant white finish suitable for domestic utility spaces.

Suitable for

• Connecting domestic washing machines to waste outlets where in-wall traps are not present
• Retrofit installations in existing laundries or utility rooms
• Situations requiring an accessible trap for inspection or maintenance

Key specifications

• Type: over-surface washing machine siphon with integrated trap ball
• Finish: white external casing
• Installation: surface-mounted / retrofittable without concealed plumbing
• Function: drainage outlet with anti-syphon / anti-odour device
• Connection: standard waste pipe interface for domestic washing machine drainage

How to use

Position the siphon on a suitable flat surface near the waste outlet and align the unit with the existing drain connection. Secure the siphon according to local plumbing practice, ensuring required pipe seals and clamps are used to prevent leaks. Connect the washing machine discharge hose to the siphon inlet and confirm that the trap ball is seated correctly to provide an effective odour seal. After installation, run a test drain cycle and inspect all joints for watertightness. Follow local building codes and manufacturer guidance for pipe gradients and support.

Usage recommendations

Regularly check the trap ball and accessible seals for debris buildup and clean as needed to maintain odour protection and drainage performance. Avoid using harsh solvents that could damage seals; use mild detergents and warm water for maintenance. If the drainage performance declines or leaks are detected, inspect connections and replace worn seals promptly to prevent water damage.
