Valve Replacement (Local)

A faulty service valve can cause leaks, poor flow, or make it impossible to isolate a tap, toilet or appliance for maintenance. This valve replacement service swaps worn, seized or leaking local valves safely, then tests everything so you can rely on proper shut-off and consistent water performance.

More information

What this valve replacement service covers

If a small isolation or service valve has failed, the aim is to restore safe control of the water supply and stop any leaks.

  • Diagnosis of the fault (leak, stiffness, low flow, failed shut-off)
  • Isolation of the water supply to the affected section
  • Removal of the defective valve and fitting of a suitable replacement
  • Checks for leaks, correct operation and water flow after refilling
  • Basic advice on using the new valve to avoid future seizure

When valve replacement is the right fix

This service is commonly needed when:

  • A valve will not fully shut off (or will not open properly)
  • You have a persistent drip or leak from the valve body or spindle
  • A toilet, tap, washing machine or dishwasher cannot be isolated
  • A stiff or seized valve risks snapping when turned
  • Flow has reduced due to internal failure or blockage at the valve

How the visit works

The work starts with confirming the cause of the issue and identifying the right isolation point. The supply is then isolated, the old valve is removed, and a new valve is fitted using appropriate fittings for the existing pipework. Finally, the system is brought back up to pressure and tested, with clear confirmation that the valve shuts off and seals correctly.

After the repair

Once fitted, the valve should operate smoothly and provide dependable isolation for future maintenance. You will be shown how to use it correctly and what to watch for in the first day or two, such as any signs of weeping at joints. If the surrounding pipework is corroded or damaged, you will be advised on the safest next step before additional work is carried out.

Frequently Asked Questions

What types of valves can be replaced?
Most small local valves can be replaced, including service valves and isolation valves on taps, toilets and appliances. If the main stop valve or older pipework is involved, it will be assessed first to confirm the safest approach.
Can you replace a valve without turning off the whole property?
Often yes, if there is an upstream isolation point that holds properly. If not, the main stop valve may need to be used or addressed first so the repair can be completed safely.
How long does a typical valve replacement take?
Many straightforward valve replacements can be completed within a single visit. Time can increase if access is restricted, the existing valve is seized, or the pipework needs minor adaptation.
Do I need to supply the replacement valve?
No, a suitable valve can be selected and supplied based on the pipe size, location and use. If you already have a valve, it can usually be fitted as long as it is compatible and in good condition.
What if the valve is stuck or the pipework is very old?
If parts are seized or pipework is fragile, care is taken to avoid causing further damage. You will be talked through the options, which may include replacing a short section of pipe for a secure, leak-free finish.
