Isolation Valve Repair

What isolation valve repair covers

A faulty isolation valve can turn a small issue into a bigger one, especially when you need to isolate a tap, toilet or appliance in a hurry. This service is designed to restore control and keep pipework watertight.

• Diagnose the cause of leaking, stiffness or failure to shut off
• Safely isolate the local supply and confirm isolation is holding
• Repair or replace the isolation valve and any related fittings if required
• Reinstate the supply and check for leaks under normal pressure
• Functional checks to confirm smooth operation and reliable shut-off

When this service is most useful

You may need isolation valve repair if you notice a slow drip from the valve body, dampness around an appliance connection, or a valve that will not turn. It is also common when preparing for an appliance change, tap replacement, or maintenance where reliable isolation is essential.

Typical signs include:

• A valve that spins but does not shut off
• A valve handle that is seized or extremely stiff
• Weeping from the spindle, compression nut, or valve body
• Reduced flow caused by a partially failed valve

How the work is delivered

First, the pipework and valve type are assessed to confirm the best repair approach and whether replacement is the safer option. The supply is then isolated and the area protected before any components are removed. After the repair or new valve is fitted, the connection is reassembled correctly and tested, then the fixture or appliance is checked to ensure normal operation.

After the repair: reassurance and prevention

Once the valve is working properly, you will have a reliable point of isolation for future work and faster control if a leak occurs. Where access allows, it can help to operate isolation valves occasionally to reduce the chance of them seizing and to spot early signs of wear.
