Where Is the Stopcock in a Bromley Victorian House?

In most Victorian and Edwardian houses in Bromley the stopcock is in one of two places: under the kitchen sink, or under the floorboards just inside the front door, where the supply pipe comes in from the street. If the house has a cellar, look there as well. Turn the handle clockwise to close it, and if it will not budge, leave it alone and use the outside stop tap at your boundary instead of forcing it.

That is the whole answer. The rest of this page is for the moment you are on your knees with a torch and the obvious places are empty.

Why is the stopcock so hard to find in an old house?

Your water comes off Thames Water’s main under the road, passes the outside stop tap (usually under a small cover in the pavement or front path), then runs under the front garden and into the house. In a house built in the 1880s or 1890s that pipe arrived long before anyone put a modern kitchen where the kitchen is now. So the original stopcock sits wherever the pipe first came through the front wall: low down under the hall or front-room floor, or in the cellar.

Later owners often added a second valve under the kitchen sink. If you find one there, follow the pipe down. If it dives into the floor heading towards the front of the house, the original stopcock is somewhere along that line, and it is the one that shuts off everything.

Where should I look, and in what order?

Under the kitchen sink

Empty the cupboard completely. You are looking for a brass or chrome tap with a crossed or round handle on the incoming cold pipe, near the back or the floor of the unit. In a refitted kitchen it may be hidden behind a removable back panel or the kickboard at the foot of the cupboards.

Under the front floorboards

This is the classic spot in the terraces and villas off Widmore Road, around Plaistow and towards Sundridge. Look for a short board, a cut section or a small hatch just inside the front door or along the hall. Many have been carpeted over. Lift the corner of the carpet and feel for a board that moves.

In the cellar

Plenty of the larger houses around Sundridge Park and Bickley have a front cellar. The supply usually comes through the front cellar wall, with the stopcock on the wall itself or close to the floor beneath it.

Cloakroom, utility room or under the stairs

Where the hall has been remodelled, a builder may have moved the stopcock into the nearest cupboard. Check under the stairs and in any downstairs toilet before you start lifting floors.

What if the house has been split into flats?

A lot of Bromley’s bigger Victorian houses are now two, three or four flats. Very often one stopcock still controls the whole building, and it may be inside the ground-floor or basement flat. Find out now which flat holds it, and agree with your neighbours how you would reach it at two in the morning. If your flat has no isolating valve of its own, ask the freeholder about fitting one. It is a small job compared with a ceiling coming down in the flat below. Our guide on a leak into the flat below in Bromley town centre covers what happens when you cannot isolate quickly.

Is the pipe going into my stopcock made of lead?

While you are down there, look at the pipe rising out of the ground into the stopcock. Thames Water says lead water pipes have been banned since the 1970s, and that you are unlikely to have them if your house was built after 1970 or fully replumbed since. A Bromley Victorian house was not built after 1970, so it is worth checking.

Lead is dull grey, soft enough that a gentle scratch with a coin shows bright silver, has no screw fittings, and its joints are bulbous swellings rather than neat connectors. If that is what you see, ask Thames Water about its lead pipe replacement scheme on 0800 316 9800. Replacing the section under your front garden is plumbing work for you as the owner; Thames looks after the part under the pavement.

How do I turn off the water in a Victorian house?

1. Find the stopcock and turn the handle clockwise until it stops. Firm hand pressure only: no hammers, no long levers.
2. If it will not move, leave it and go to the outside stop tap at your boundary. You need a stop tap key, a long T-shaped tool that hardware shops sell, to reach down and turn it clockwise.
3. Open the cold taps in the kitchen and bathroom to drain what is left in the pipes.
4. If you have a loft tank, open the bathroom cold taps fully as well, because the tank keeps feeding them after the mains is off.
5. Switch off the electrics at the consumer unit for any room where water is near sockets, lights or switches.
6. Put towels and buckets under the leak, move anything valuable, then call us.

Why does my stopcock not turn?

Bromley’s water is hard, around 280 mg/l in Thames Water’s Bromley Town supply zone, which puts it in Thames’s “hard” band. Over years the scale builds up inside the valve and around the spindle, and a stopcock that has not been touched since the last owner moved in can seize solid. Forcing it is how people snap the spindle or crack the old pipe it sits on, which turns a dripping tap into a flood.

If yours is stiff, the fix is to have it replaced on a calm day, usually with a modern quarter-turn valve that is easy to use in a hurry. While the plumber is there, it is a good moment to fit a separate valve for each flat in a converted house, or an isolating valve under the sink for the kitchen.

Test it this weekend

Once you have found it, turn it off and on again. Check that the water actually stops at the kitchen tap. Then tie a label to it, tell everyone in the house where it is, and keep a torch nearby. If the outside stop tap is under a cover you cannot lift, or full of soil, that is worth sorting before winter too.

If you have water bubbling up outside rather than a problem indoors, read whether a street leak is Thames Water’s or yours before you call anyone. For everything else in BR1 and BR2, see our Bromley area page.
