Where is my stopcock located?

In most UK homes, the internal stopcock is under the kitchen sink, usually on the pipe that comes through the wall or floor from the street. Some properties have them in a downstairs cloakroom, utility room, or under the stairs. There is also an external stop valve at the boundary of your property, typically under a small metal cover in the pavement or front path.

Can a seized stopcock be freed without replacing it?

In many cases, yes. A plumber can apply penetrating oil and carefully work the valve until it moves freely again. However, if the valve body is cracked, heavily corroded, or the internal washer has disintegrated, replacement is the safer long-term option. Your plumber will advise on the best approach after inspection.

How long does a stopcock replacement take?

A straightforward stopcock replacement typically takes between one and two hours, including draining down the affected section of pipe and testing the new valve. If additional pipework is needed due to corrosion around the old valve, it may take slightly longer.

Why a Working Stopcock Matters

Most homeowners never think about their stopcock until they need it urgently. When a pipe bursts or an appliance starts leaking, the first thing any plumber will ask you to do is turn off the water at the stopcock. If the valve is seized solid, corroded, or the handle snaps off, you cannot stop the flow — and the damage escalates rapidly.

In many Liverpool properties, especially those built before the 1980s, the internal stopcock sits under the kitchen sink and has not been turned in years. Mineral deposits from Merseyside’s hard water build up around the valve seat, gradually seizing the mechanism. By the time you need it, it will not budge.

Our plumbers can free seized stopcocks, replace worn washers and seals, or fit an entirely new valve if the existing one is beyond repair. If you also need work on your pipework or have experienced a flood because your stopcock failed, we can arrange both jobs through a single call to 0333 240 8428.

How Stopcock Repair Works

Describe Your Stopcock Problem

Tell us whether the stopcock is seized, leaking from the spindle, or if the handle has broken. Let us know the location of the valve and whether you currently have an active leak that needs isolating. This helps us send the right plumber.

Inspection and Quote

Your plumber will inspect the stopcock, check the surrounding pipework for corrosion or damage, and determine whether a repair or full replacement is the best course of action. You will receive a clear quote before any work starts.

Repair or Replacement

For seized stopcocks, the plumber will attempt to free the mechanism and replace internal seals. If the valve body is corroded or damaged beyond repair, a new stopcock is fitted. The water supply is temporarily shut off at the external stop valve during replacement.
