Details

When installing a deeper basin, changing a vanity unit, or modernising your bathroom, the new plumbing layout often leaves a frustrating gap where your existing trap can’t reach the waste outlet. Trying to force or stretch the pipes to make them fit cross-threads the plastic and inevitably causes slow, structural-damaging leaks under the sink. Ripping out all the rigid wall pipework just to adjust the height is a massive, time-consuming headache.

The McAlpine S12A-2 2″ Extension solves this exact problem. It threads straight onto your basin waste to add the perfect 2″ drop, connecting directly into your trap with a reliable rubber seal. It turns a frustrating plumbing misalignment into a simple, 30-second fix.
