McAlpine single pipe siphon 1.5" HC7HC17PR

McAlpine single pipe siphon 1.5" HC7HC17PR is a compact plumbing trap engineered for connection to 1.5-inch drainage pipework. It creates a reliable water seal that prevents sewer gases from entering fixtures while allowing efficient drainage for sinks, basins or appliances. The siphon’s compact single-pipe form factor makes it suitable for installations where space is limited but a standard water seal is still required.

Advantages

The single pipe design provides a simple, space-saving trap that is easy to install and maintain. Constructed from durable materials, it resists corrosion and retains its sealing properties over time. Its standard connection dimensions ensure compatibility with typical 1.5-inch domestic and light commercial drain systems, and the smooth internal profile promotes free flow and reduces the risk of blockages.

Suitable for

• Sinks and basins with 1.5-inch drainage outlets
• Domestic and light commercial washrooms
• Compact installations under cabinetry or where vertical space is limited
• Connection to appliances with 1.5-inch waste outlets

Key specifications

• Connection size: designed for 1.5-inch drainage pipework
• Type: single pipe siphon (trap) providing a water seal
• Form factor: compact, single-pipe configuration for restricted spaces
• Material characteristics: durable, corrosion-resistant plastic suitable for standard wastewater
• Function: prevents sewer gases while permitting reliable drainage

How to use

Install the siphon between the fixture’s waste outlet and the drainage line using the matching 1.5-inch connections. Ensure all joints are securely tightened and aligned to prevent leaks. After installation, run water through the fixture to verify a stable water seal and check for any signs of leakage. Periodic visual inspection and clearing of any debris in the trap will help maintain flow and sealing performance.

Usage recommendations

For reliable operation, fit the siphon where the pipe dimensions and local plumbing regulations match the 1.5-inch connection. Avoid using harsh chemical cleaners that could degrade plastic components; use mechanical clearing or mild, manufacturer-recommended cleaners if blockages occur. If installation requires non-standard angles or additional fittings, use compatible connectors designed for 1.5-inch waste systems.
