The McAlpine ST90-HPB trap body is designed for 2" waste pipe connections. The multifit outlet accommodates 2" plastic (solvent weld or push-fit) and 2" copper pipes.
The 50mm water seal creates a barrier that prevents unpleasant sewer gases and odors from rising from the waste pipe and entering the living space.
Yes, this trap body is designed to be compatible with McAlpine's range of trap tops and extension pieces, allowing for customization of the trap depth.
The trap body achieves a flow rate of 50 liters per minute, tested according to BS EN 274-2:2002 standards.
The height of the trap body itself is 87mm. This does not include the height of any connected trap tops or extension pieces.
It is suitable for general plumbing applications requiring a 2" waste connection and a 50mm water seal. Ensure your installation has adequate vertical space for the trap body and any extensions.
It is supplied with a 135° Bend BSP coupling nut for an angled connection. However, specific pipe adapters or seals for the multifit outlet might be needed depending on the exact pipe type and system.
Ensure the trap is correctly installed with no air leaks. Check that ventilation to the waste pipe system is adequate. If the trap is used infrequently, pour water into the trap periodically to maintain the seal.
Check the trap body and any connected trap tops or waste pipes for obstructions. Flush with hot water. If the blockage persists, the trap may need to be disassembled for cleaning.
Ensure all connections are tightened correctly. If using solvent weld connections, ensure proper preparation and solvent application. Check seals and washers for damage and replace if necessary.
Setup: The ST90-HPB trap body is designed for straightforward installation. Connect the 2" multifit outlet to your 2" waste pipe (plastic or copper). Ensure a secure, watertight seal. The trap body can then be connected to a suitable trap top or extension piece from the McAlpine range to achieve the desired trap depth. The supplied 135° Bend BSP coupling nut can be used for an angled waste connection.
Compatibility: This trap body is specifically designed for 2" waste pipe systems. The multifit outlet is compatible with 2" solvent weld, push-fit plastic pipes, and 2" copper pipes. It is intended for use with other McAlpine trap tops and extension pieces to create a complete trap assembly.
Care: To maintain optimal performance and hygiene, regularly check the water seal. Periodically flush the trap with hot water to clear any minor debris. For deeper cleaning, the trap can be disassembled (following McAlpine's assembly instructions) and cleaned with a mild detergent and water. Avoid using harsh abrasive cleaners or solvents that could damage the plastic components.
