Signs Your Stopcock Needs Replacing

⚠️

Won't turn or is seized

You try to turn it and the handle won't budge. Gate valves seize after years of not being used. If you can't turn it, you can't isolate the water in an emergency. It needs replacing before you have a burst pipe or leak and can't stop the water.

⚠️

Leaking from the spindle

Water drips from the top where the handle goes through. The gland packing has perished. You can sometimes tighten it, but if the valve's old, it's better to replace it before it gets worse.

⚠️

Doesn't shut water off properly

You turn it fully clockwise but water still dribbles through. The gate inside is worn or corroded. You can't isolate the water properly, which is a problem if you have a leak or need to work on the pipes.

⚠️

Handle snaps off

You try to turn it and the handle snaps off in your hand. The internal mechanism has corroded or seized and the handle's weakened. You'll need a new stopcock immediately.

How We Replace Stopcocks

1

Turn off the boundary stop cock

We'll locate the boundary stop cock in the pavement outside and turn it off. This isolates the water supply so we can work on your stopcock without flooding.

2

Cut out the old stopcock

We'll cut out the old valve using a pipe cutter. If it's soldered in, we'll heat the joints. Old gate valves are often crusted with limescale and won't unscrew nicely.

3

Fit the new quarter-turn valve

We'll measure the gap and fit a new quarter-turn lever valve. These turn 90 degrees to shut off (not multiple turns like old gate valves), they don't seize, and they're easier to use in an emergency. We'll solder or compression-fit it.

4

Test and restore water

We'll turn the water back on at the boundary stop cock and check for leaks. We'll test the new valve opens and closes smoothly. Job done.

When to Replace vs Repair

Won't fully close

If your stopcock still drips when turned off, the washer or valve seat is worn. We can replace just the valve mechanism in some cases.

Seized and won't turn

Common in stopcock that haven't been used for years. We'll try freeing it first, but if the spindle is corroded, full replacement is safer.

Leaking from the spindle

Usually fixable with gland nut tightening or new packing. But if the body is cracked, it needs full replacement.

Old gate valve style

Upgrade to a modern quarter-turn lever valve. They're faster to close in an emergency and last longer.

Common Questions

Got questions? Here's the quick answers.

How much does stopcock replacement cost in Chatham?
Stopcock replacement in Chatham typically costs between £120 and £250 depending on the location and accessibility of the existing stopcock.
Where is my stopcock?
Usually under the kitchen sink, in a utility room, or under the stairs. If you cannot find it, we can locate it for you. Every home should know where their stopcock is.
Why would a stopcock need replacing?
Stopcocks seize up over time if they are not turned regularly. A seized stopcock cannot shut off the water supply in an emergency, which is a serious risk.
