McAlpine single pipe trap HC7HC13 1.5" for basin and sanitary fittings

McAlpine single pipe trap HC7HC13 1.5" for basin and sanitary fittings is a compact plumbing trap designed for installation beneath washbasins and other sanitary fixtures. The trap creates a reliable water seal that prevents sewer gases from entering indoor spaces while enabling direct connection to standard 1.5" waste outlets. Its slim profile makes it suitable for installations where space is limited, offering a practical solution for residential and light commercial washroom plumbing.

Advantages

The single pipe design provides a straightforward connection to basin waste pipes, simplifying installation and reducing the number of joints. Its compact size allows it to fit into confined cabinet spaces and beneath shallow basins. Constructed to meet typical household plumbing requirements, the trap maintains a water seal to block foul odours and supports easy alignment with standard 1.5" fittings. The design also facilitates routine maintenance and inspection without complex disassembly.

Suitable for

• Under-sink installations in kitchens, bathrooms and utility rooms
• Basin and washbasin sanitary fittings with 1.5" waste outlets
• Small commercial washrooms and guest facilities
• Tight or shallow cabinet spaces where a compact trap is needed

Key specifications

• Connection size: 1.5" compatible with standard basin waste outlets
• Type: single pipe (bottle) trap for basin and sanitary fittings
• Profile: compact/slim design for limited space installations
• Function: water seal to prevent sewer gas ingress
• Application: residential and light commercial washroom plumbing

How to use

Position the trap directly beneath the basin waste outlet and align the 1.5" connection to the waste spigot. Ensure sealing surfaces are clean and use the appropriate sealing ring or washer supplied with the fitting to secure a watertight joint. Tighten connections by hand or with a suitable tool to the manufacturer’s recommended torque, avoiding over-tightening. Verify the trap sits level and that the outlet pipe provides adequate fall to the soil stack or waste line. After installation, run water to check for leaks and confirm that the water seal is maintained.

Usage recommendations

Use with compatible 1.5" basin waste fittings and inspect periodically for blockages or leaks. Avoid disposing of grease, fibrous materials, or large solids down the basin to reduce the risk of clogging. If access is restricted, allow sufficient clearance during installation for future maintenance and cleaning.
