Stopcock Repair

A working stopcock is essential for controlling your water supply during leaks, repairs, or routine maintenance. Stopcock repair restores smooth shut off, fixes drips and seepage, and helps prevent small issues becoming bigger water damage.

More information

What stopcock repair covers

If your internal stopcock is stiff, leaking, or not shutting off fully, this service is designed to get it operating safely and reliably again. Typical outcomes include:

  • Freeing or repairing a stiff stopcock so it turns smoothly
  • Stopping leaks from the spindle/gland, body, or nearby joints
  • Restoring full shut off so the incoming supply can be isolated when needed
  • Replacing worn internal parts where possible, or fitting a like-for-like replacement valve
  • Confirming correct operation with on-site testing before completion

When this service is most useful

Stopcock problems often show up at the worst time. Book a repair if:

  • The stopcock will not turn, or only turns part way
  • You can see drips, damp, or staining around the valve
  • The valve turns but does not fully stop the flow
  • You are preparing for other plumbing work and need dependable isolation
  • You manage a rented property or small premises and want to reduce leak risk

What’s involved on the day

The job starts with a quick assessment of the valve type, location, and any signs of corrosion or previous repairs. The water supply is isolated as needed, then the fault is addressed by tightening, repacking, reseating, or replacing defective components. Finally, the stopcock is tested for smooth operation and reliable shut off, and the area is checked for any further seepage.

Aftercare and ongoing value

You will be shown how to operate the stopcock safely and how far it should turn. If access is awkward, you can also ask about improving accessibility or fitting a more user-friendly valve so it is easier to shut off quickly in an emergency.

Frequently Asked Questions

Can a stopcock be repaired or will it need replacing?
Many leaks can be fixed by adjusting or replacing internal seals, or by repairing the spindle packing. If the valve body is damaged or badly seized, replacement is usually the most reliable option.
Will you need to turn off the water to the whole property?
Often yes, because the stopcock controls the incoming mains supply. Where possible, we will keep downtime minimal and confirm water is back on before we leave.
What if my stopcock is stuck and I can’t turn it?
Avoid forcing it, as older valves can snap or start leaking. We use appropriate tools and methods to free or replace the valve safely.
How do I know if my stopcock is leaking?
Look for drips, damp patches, corrosion, or limescale around the valve and pipe joints. A slow leak can also show up as unexplained moisture in the cupboard or floor void nearby.
Where is the internal stopcock usually located?
Common locations include under the kitchen sink, in a utility room, in a downstairs toilet, or near where the mains pipe enters the property. If you cannot find it, we can help locate it during the visit.
