Water going where it should not? Ring 01462 506374
Deal with the stopcock first. Turn it clockwise until it stops, then pick up the phone. Somebody answers, at any hour, on any day of the year, and you get an honest time for an engineer rather than a line designed to end the call.

The Cam splits the city, and it splits the water supply too
Cambridge Water supplies the mains here, and it divides the city along the river. North of the Cam you sit in the Cambridge North water quality zone, Z1. South of the Cam you sit in Cambridge South, Z2. By ward that puts Arbury, King’s Hedges, Castle, Newnham and both Chesterton wards in the north zone, and Market, Petersfield, Romsey, Coleridge, Abbey, Cherry Hinton, Queen Edith’s and Trumpington in the south.
The published zone figures are 295 mg/l of calcium carbonate for Cambridge North, around 20.6 Clark degrees, and 286 mg/l for Cambridge South, around 20.0 Clark. Those are Cambridge Water’s published figures for the supply zones, not readings we have taken on your tap. The company says it plainly itself: all of the water it supplies is hard.
It has always been that way. Hobson’s Conduit, cut between 1610 and 1614 to bring water into the city from the springs at Nine Wells near Great Shelford, still runs down Trumpington Street and Lensfield Road.
What that means in a Cambridge house is predictable. Tap seats score and cartridges pack solid. Shower valves lose their grip on temperature. Isolation and gate valves look serviceable and do nothing when you close them. Immersion elements fur up and a cylinder takes longer and longer to recover.
Finding the stopcock, and why it depends on when your house was built
The first question on any emergency call is where your stopcock is. A lot of people have never looked.
In the Victorian terraces off Mill Road it is usually under the kitchen sink or in the front room against the wall the main comes through, often behind units fitted long afterwards. In the interwar and post war stock north of the river it is generally under the sink or in the hall cupboard. In the 2000s and 2010s estates it is commonly in a service cupboard near the front door, with a labelled manifold nearby. In flats there is usually a valve inside your own front door and a communal one elsewhere in the block.
Out at the boundary there is a second stop tap, under a small lid set into the pavement or verge. Cambridge Water looks after the main and the run up to that boundary. From the boundary into your home the supply pipe is yours, including the cost of repairing it.
Spend two minutes this week. Find it, close it, open it again, label it. If it will not turn, get it changed while the house is dry.
The everyday work we do across Cambridge
Burst and split pipes. Dripping taps, reseating and replacement. Stopcocks, isolation valves and service valves, so the next repair does not mean draining the whole house. Toilet and cistern work, flush valves and the slow seep at a pan connector that quietly rots a floor. Radiators, thermostatic valves and balancing a system that heats the back bedroom and nothing else. Outside taps, complete with the double check valve the regulations require. Washing machine and dishwasher plumbing. Waste pipes and traps. Cylinders, immersion heaters and unvented servicing. Poor flow and pressure.
We are Gas Safe registered, so if the thing leaking turns out to be a boiler, a filling loop or a heating pipe, the same engineer deals with it. Electrical work is carried out by qualified electricians and certificated as part of the job.
Small jobs count. A single dripping tap is a job worth doing.
The Cambridge properties where a job takes longer than you would think
Romsey Town and the streets off Mill Road, east of the railway bridge. The bulk of these houses went up in the ten years after 1885, built for railway workers as the population along Mill Road climbed from a few hundred to more than twenty five thousand within the century. They are narrow, deep and tightly packed, most have had a rear extension and a loft conversion added at different times, and the pipework is a stack of eras sitting on top of each other. Half the job here is proving what feeds what before anything is cut. Parking is the other half, so we plan the approach before we set off.
Petersfield, on the city side of the bridge. The same broad era, developed on college land with streets named after college fellows. Old supply pipework is common here, and where it has never been renewed we would rather look at it in daylight than meet it in an emergency.
Chesterton, north of the Cam. Largely a twentieth century suburb, with a large housing association estate in East Chesterton and steady infill since Cambridge North station opened in May 2017. Post war semis here tend to have copper in imperial sizes needing adaptors to meet modern fittings, gate valves on the tank feeds that have not moved in decades, and cylinders well past their useful life.
Eddington and the North West Cambridge development. Up to 3,000 homes across a 150 hectare University site, and the one part of the city where you have to check which pipe you are on. The homes were built with a second set of pipework for a non potable supply, designed to carry rainwater collected through swales into Brook Leys lake back for toilet flushing and irrigation, and an energy centre supplies district heating. The recycled network was finished in 2021 but has never been switched on because of a regulatory gap, so for now both circuits carry mains water. Two sets of pipework in one property still changes how a leak is traced and what may be connected where.
Great Kneighton at Clay Farm, Trumpington Meadows and Darwin Green. Newer estates on the southern and north western edges. New build brings its own faults: plastic push fit never pushed fully home, manifold valves left part closed at handover, and traps full of grout from the fit out.
The historic core and the college terraces. If a property is listed or sits in a conservation area, work that would otherwise be permitted can need consent from Greater Cambridge Shared Planning, and trees in a conservation area are automatically protected. That matters for anything on an external wall or any digging near a tree, and we flag it before we start.
Ground, gravel and what is under a Cambridge street
Cambridge is low ground, roughly 6 to 24 metres above sea level, sitting on gault clay and the chalk marl known locally as Cambridge Greensand, with terrace gravel above it. That matters when a supply pipe leaks underground. Water in gravel travels sideways and surfaces somewhere unrelated to the failure, so digging where the wet patch is often means digging in the wrong place. On the clay, seasonal shrinkage puts strain on rigid joints and old lead tails. It is why we trace before we dig.
Winter, and where Cambridge pipes actually give way
The same three places, every year. Loft runs where the insulation has been laid over the pipe instead of under it, so the pipe gets the cold and none of the warmth from the house. Unheated garages, porches and outbuildings, usually on the run out to an outside tap. And pipes chased into an external wall in an extension with very little between them and the weather.
If something has already frozen, shut the water off, keep any naked flame away from it, and call. Splits only show themselves once the ice thaws, so the quiet hour before that is the hour to get things isolated.
Genuine 24/7 emergency plumbers in Cambridge
Round the clock means an engineer on the road, 365 days a year, not a message service that passes your details to somebody in the morning. The overnight calls come in four flavours: a split pipe, a flexible tap connector that has given up under a sink, a cistern or tank running over, and a cylinder or boiler leaking.
Most emergencies are settled on the first visit from what is already on the van. Where a permanent fix needs something that is not on the van, we make the property safe and watertight, tell you plainly what it needs, and come back to finish it.
What it costs
Every job is quoted on what it actually involves. You get the figure before work starts, and if what is behind the panel changes the job, you hear about it there and then rather than on the invoice. Work outside normal hours is charged at a different rate, and you hear that rate before we leave the yard.

Frequently Asked Questions
How quickly can a plumber get to me in Cambridge?
For a genuine emergency we move as fast as the roads allow, coming in on the M11 or the A10. Level crossings and the city centre restrictions can add time, so we give you a realistic window on the phone rather than an optimistic one.
Where will my stopcock be?
Usually under the kitchen sink or close to where the main enters the house, and in newer estates often in a service cupboard by the front door. In a flat there is normally a valve inside your own front door and a communal one elsewhere in the building.
Why do taps and shower valves scale up so fast here?
Because the water is hard. Cambridge Water publishes 295 mg/l of calcium carbonate for the Cambridge North zone and 286 mg/l for Cambridge South. Scale scores tap seats, seizes valves and ruins the temperature control on a shower.
Who is responsible for the pipe between the road and my house?
You are. Cambridge Water looks after the main and the run up to your boundary. From the boundary into the property the supply pipe belongs to the homeowner, and so does the repair cost.
My house has a second supply that is not for drinking. Can you work on it?
Yes. Homes at Eddington were built with a separate non potable network, intended to carry harvested rainwater for toilet flushing and irrigation alongside the normal mains. That recycled supply has not yet been brought into service, so at present both circuits carry mains water, but the two systems must still stay completely separate and we identify which pipework we are on before touching anything.
Do you work on listed buildings and in conservation areas?
Yes, and it is routine in a city like this. Work that would normally be permitted can require consent from Greater Cambridge Shared Planning, and trees in a conservation area are protected automatically. We use existing pipe routes where we can and raise anything that needs consent first.
