If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

A disturbed trap can leak because seals are displaced, threads are misaligned or pipework is under strain. Tightening harder may distort a connection. Correct fit and support matter as much as a new washer.

Before arranging the visit

Tell the plumber which parts were moved and whether the leak occurs only during drainage.

Choosing the appropriate plumbing visit

We check the visible fault, isolation, pipe condition and access before agreeing the repair scope. Our waste pipes & traps page explains the related work and how an assessment is arranged.

Where the findings point to bottle trap replacement, read the bottle trap replacement service details before discussing the repair scope. The actual fitting and access determine the work needed.
