When Should You Replace a Leaking Tap?

A dripping tap might seem like a minor issue, but here’s how to know when it’s time to
repair or replace it.

A dripping tap is easy to ignore, but that steady drip can waste hundreds of litres of water a year and often points to a part that’s wearing out. Here’s how to know whether a repair will do, or whether it’s time for a replacement.

Common causes of a leaking tap – A worn washer or O-ring (most common in older, traditional taps) – A
damaged valve seat, which allows water to bypass the seal – A faulty cartridge in mixer or lever-style taps –
Loose or corroded internal components

When a repair makes sense If your tap is relatively new, well-built, or from a good-quality brand,
replacing the washer, O-ring, or cartridge is usually a straightforward and affordable fix. This is often all
that’s needed to stop the drip completely.

When replacement is the better option – The tap is old, worn, or was a low-cost model to begin with —
repeated repairs may cost more over time than a new tap. – There’s visible corrosion, pitting, or mineral
build-up on the tap body itself. – The tap wobbles, feels loose, or the finish is cracked or peeling. – You’re
renovating a kitchen or bathroom anyway, and it makes sense to upgrade. – Replacement parts for the
specific tap model are no longer available.

Why you shouldn’t leave it dripping Beyond the wasted water and higher bills, a constant drip can stain
sinks and basins, and in some cases, the moisture can encourage mould around the tap base or nearby
cabinetry.

Getting it right the first time Taps look simple, but small mistakes during a repair or fitting, like overtightening a valve or fitting the wrong washer size, can cause bigger leaks down the line. A professional fix or fitting ensures it’s done properly and won’t need revisiting.

best option and get it fitted properly.
