McAlpine Syphon 200+255CB — Sink/Basin Waste Trap with Bottle Trap Connection (mpn 200+255CB)

The McAlpine Syphon 200+255CB is a compact sink and basin waste trap designed to collect and discharge wastewater while preventing sewer gases from entering indoor spaces. This bottle-trap style unit includes a removable chamber for straightforward cleaning and maintenance, and its configuration suits standard domestic and light commercial basin and sink installations where a small, serviceable trap is required.

Advantages

The design combines a compact bottle-trap profile with a serviceable removable chamber, allowing routine access without dismantling the whole trap. Its straightforward geometry supports simple installation and maintenance, and the unit is compatible with typical domestic sink and basin plumbing layouts. Materials and construction are selected to provide reliable water seal performance and resistance to everyday household wastewater conditions.

Suitable for

• Domestic bathroom basins and kitchen sinks where a compact trap is needed.
• Light commercial washrooms with standard under-sink clearance requirements.
• Installations requiring a removable chamber for periodic cleaning or inspection.

When it may not be suitable

This bottle-trap style syphon is not intended for heavy industrial drainage or installations that require large-capacity traps or specialised waste handling. It may not be appropriate where backflow prevention devices or non-standard pipe connections are mandatory without additional adapters or modifications.

Key specifications

• Type: Bottle-trap style waste trap for sinks and basins
• Function: Wastewater collection and discharge with water seal to block sewer gases
• Serviceability: Removable chamber for cleaning and maintenance
• Application: Domestic and light commercial sink/basin installations
• Form factor: Compact, under-sink/basin profile suitable for tight clearances

How to use

Fit the trap to the sink or basin outlet and align the waste outlet to the existing drain pipe following local plumbing standards. Ensure all seals and compression fittings are correctly tightened to prevent leaks. The removable chamber can be unscrewed or removed according to the product construction for periodic cleaning: empty trapped debris, rinse the chamber, and reassemble components securely. If any leak or odour persists after installation, check alignment, sealing washers and tighten connections or consult a qualified plumber.

What to consider before purchase

• Confirm compatibility with your sink or basin outlet size and the existing drain pipe diameter.
• Verify under-sink space and clearance to ensure the compact bottle-trap profile will fit.
• Determine whether additional adapters or fittings are needed for non-standard plumbing connections.

Usage recommendations

To maintain performance, inspect and clean the removable chamber periodically to remove hair, soap residue and debris. Use mild cleaning agents and avoid aggressive chemicals that could damage seals. After reassembly, run water to verify a watertight seal and correct drainage.
