McAlpine SR10 1 1/4″ Running P Trap — 75mm Water Seal Basin Waste

Features

This genuine McAlpine SR10 1 1/4″ running P trap is a premium, inline drainage solution engineered for standard bathroom basin waste pipe systems. Manufactured in the UK from high-density white polypropylene, this specialized through-trap features universal multifit compression connections on both ends to splice directly into pipework rather than threading onto a waste outlet. Built with an offset alignment where one end sits slightly higher than the other to maximize water flow, it features a full 75mm water seal to completely block foul sewer odours.

Details

Standard waste traps require direct attachment to the threaded thread of a basin waste, making them completely useless when you need to fix a drainage issue further down the pipe run. Trying to rig up an incorrect trap configuration in the middle of a pipeline restricts water movement. Consequently, slow-moving water allows hair, soap scum, and heavy sludge to settle in the line. This build-up creates frequent blockages and dirty tracking leaks at the joints. Furthermore, cheap universal unbranded traps frequently suffer from thin plastic threads that cross-thread easily during assembly. Because these poor-quality units cannot establish a rigid seal across different pipe materials, foul sewer gases back up into your home, leaving you with an unhygienic bathroom environment.

Fortunately, installing this genuine McAlpine SR10 running trap solves these alignment and sealing headaches completely. Because McAlpine engineered this through-trap with universal multifit compression joints on both ends, it pieces directly into your pipework without needing a waste thread connection. Additionally, the smart offset body ensures one end sits slightly higher than the other. Therefore, you completely optimize the gravitational water flow to keep the pipe self-clearing. Meanwhile, the heavy-duty polypropylene build creates an impenetrable 75mm water seal that fully complies with BS EN 274-1:2002 standards. As a result, you secure a completely certified, watertight, and odor-free drainage line that protects your home for decades.
