Features

This genuine McAlpine shower waste installation tool is a dedicated plastic spanner key engineered to install, tighten, or remove compatible shower waste tops safely. Bearing the part number STWSPANNER, this compact tool sits directly into the central opening where the removable grid normally pops out. It locks perfectly into the internal notches of McAlpine 70mm and 85mm STW series shower waste flanges.

Details

Standard threaded shower wastes must be securely tightened down to compress the underlying washers and create a permanent, watertight seal. However, because the outer chrome flange is perfectly smooth, there is no flat surface for a standard metal spanner or pipe wrench to grab onto. Consequently, installers often resort to makeshift methods—such as wedging the handles of a pair of pliers or a flathead screwdriver into the drain notches. Unfortunately, this concentrated pressure frequently slips, gouging the premium chrome plating or stress-cracking the plastic housing completely.

Fortunately, using this authentic McAlpine shower waste installation tool solves this installation hazard completely. Specifically, the moulded circular base drops directly into the central waste opening, distributing the torque evenly across the internal notch system without slipping. Additionally, because the tool is crafted from a high-impact, non-marring plastic, it cannot scratch or bite into mirror-polished metal surfaces. Therefore, you get the perfect amount of leverage to clamp the trap down tightly, ensuring a fast, professional, and leak-free installation every time.
