Details
Upgrading a kitchen sink, swapping out a bath, or installing a new shower tray regularly creates frustrating alignment issues underneath. A deeper replacement basin or a slightly altered floor level often means your existing 1.5″ waste trap sits just an inch too low to meet the new drain outlet thread. Because standard plastic plumbing traps are rigid, forcing a mismatched connection cross-threads the plastic, causing an active drip that rots out vanity flooring or leaks behind bath panels. Buying and cutting a whole new trap assembly just to gain 25mm of clearance is an expensive, time-consuming hassle.
Using this genuine McAlpine T12A-1 trap waste extension solves these annoying structural shortfalls in under a minute. Acting as a solid, fixed-distance coupler, this 1-inch spacer screws directly onto your waste outlet thread and drops the connection point down to the exact height your trap requires. The pre-installed black rubber washer creates an airtight compression seal against the waste, removing the need for messy plumbers’ putty or PTFE tape. You salvage your existing under-sink pipework configuration, stop leaks before they start, and finish the job without extra plumbing modifications.
