McAlpine A10A 32mm 1¼” Adjustable Inlet Bottle Trap
McAlpine A10A is a 32mm / 1¼” adjustable inlet bottle trap for basin waste installations. It is designed for bathroom basins, cloakroom basins, vanity units and general domestic basin pipework where the trap height may need to be adjusted during fitting.
McAlpine A10A Trade Overview
The McAlpine A10A bottle trap is a practical choice for plumbers, bathroom fitters and maintenance teams. The adjustable inlet helps when lining up the trap with existing basin waste pipework, making it useful for repair, replacement and refurbishment work.
This trap has a 75mm water seal to help prevent drain odours from coming back through the basin waste. It also features a 1¼” Multifit compression outlet, which is designed to suit common waste pipe materials including plastic, copper and lead pipe.
The white polypropylene construction gives a clean and simple finish below the basin. It is suitable for everyday domestic and trade plumbing jobs, including new basin installations and replacement of old or leaking 32mm traps.

Why Choose an Adjustable Inlet Bottle Trap?
An adjustable inlet bottle trap is useful when the basin waste outlet and existing pipework do not line up perfectly. The adjustable inlet gives the installer more flexibility compared with a fixed inlet trap, which can help save time on repair and replacement jobs.
The McAlpine A10A is especially useful for maintenance work, rental property repairs and bathroom refurbishments where existing waste pipework is being reused. The Multifit outlet also helps when connecting to different waste pipe materials.
Installation Notes
Before fitting, check that the basin waste outlet and pipe size are suitable for a 32mm / 1¼” trap. Cut the waste pipe cleanly and make sure it is fully seated into the compression fitting. Adjust the inlet to suit the basin waste position, then tighten the compression nuts securely by hand. After fitting, run water through the basin and check all joints for leaks.
