Three Common Causes of a Dripping Tap and Their Fixes

A dripping tap normally points to one of three serviceable areas. Identify the tap type before ordering parts.

A safe job starts with isolation and a recovery plan before any tool is used. Confirm that the task is genuinely within normal user maintenance, have the correct parts ready and stop if the installation differs from the expected layout.

Prepare before you start

A dripping tap can waste metered water and leave limescale staining, but rushing the repair can damage old isolation valves or worktops. Prepare the parts, protect the finish and confirm both hot and cold isolation before dismantling.

Three common causes

• Worn washer or damaged seat in a traditional compression tap. Protect the finish, identify the exact part and restore water slowly. A careful test above and below the fitting is part of the repair.
• Failed ceramic cartridge in a quarter-turn tap.
• Perished O-ring or seal causing leakage around the spout or handle. Dry the area first, then check it again under normal operating conditions. The timing and first point of fresh moisture are more useful than the final spread of the stain.

A practical, safety-first sequence

1. Dry the tap and observe the exact leak point through a normal operating cycle.
2. Confirm that the hot and cold supplies can be isolated without forcing old valves.
3. Identify the tap make, handle fixing and cartridge or washer arrangement before ordering parts.
4. Plug the waste so small screws cannot fall into the trap and protect decorative finishes from tools.
5. Reassemble in the correct order and avoid overtightening seals or ceramic components.

Common mistakes to avoid

• Forcing a seized isolation valve immediately before dismantling the tap.
• Using pliers directly on chrome or painted finishes.
• Overtightening flexible hoses, cartridges or compression joints.
• Checking only the spout and missing a slow leak inside the cabinet.

UK context and safety

Isolate both supplies, protect the finish and follow the maker's parts diagram. Do not force a seized valve or overtighten a ceramic cartridge.

Isolate both supplies and verify that flow has stopped before dismantling a mixer tap. Take extra care with hot-water supplies and boiling-water taps. If safe isolation is unavailable or an old valve begins to leak, stop and arrange a controlled repair rather than forcing it.

Prevention and ongoing care

A repair is more durable when the surrounding causes and future access are considered as part of the job.

• Remove limescale with a product and method suitable for the finish.
• Inspect flexible connectors and cabinet bases for early signs of seepage.
• Keep product details so the correct cartridge can be sourced later.
• Repair drips before mineral deposits damage seats and finishes further.

When to call PHD24

PHD24 can identify the tap, replace serviceable parts and check the isolation valves.

PHD24 can identify the leak point, assess whether parts remain available and compare repair with replacement. The visit can also address weak isolation valves or damaged connections that would make a simple tap repair unreliable.

Call promptly if water cannot be isolated, wastewater is entering the property, heat or hot water has failed in vulnerable circumstances, or the fault involves gas, wet electrics or a risk to the building. For a non-urgent visit, photographs and a short history help PHD24 plan the right first attendance.
