Low pressure in CM23 is not always your plumbing
Bishop’s Stortford has a documented history of supply problems, and it is worth knowing that before you start pulling a shower apart.
In July 2026 Affinity Water reported low pressure and reduced supplies across the CM23 postcode area, putting it down to a combination of exceptionally high demand in prolonged hot weather and a technical issue at one of its pumping stations. Affinity’s own words at the time were that water was “being used faster than we can refill our storage tanks and move it through the network”. There has also been a separate multi-day loss of supply in the town serious enough that Affinity delivered bottled water.
So when someone rings us about weak flow, the first thing we establish is whether the problem is inside the boundary or outside it. If the neighbours have it too, it is a network issue and no amount of new pipework will fix it. If it is only your house, then we are looking at a partly closed stopcock, a furred up section of old pipe, a failing pressure reducing valve or a fault on the private supply pipe.
That distinction also matters when anyone is thinking about a combi boiler or an unvented cylinder here. Both live or die on incoming flow rate, and both should be specified on a measured figure rather than an assumption.
Where the stopcock lives, by era
The historic core around Market Square. Buildings inside the conservation area range from the 15th century and earlier through to the 20th, with 25% of the listed stock dating from each of the 17th and 18th centuries. Stopcocks in properties like these are wherever the last four generations of plumbers left them, often at the front of the building on the incoming wall, sometimes under a stair or behind a cupboard base.
The Victorian and Edwardian villas on Hadham Road, Maze Green Road, Stansted Road and Dunmow Road. Usually under the kitchen sink or in a cellar head. Big houses with bay windows, decorative chimneys and later rear additions tend to have more than one isolation point, and not all of them work.
Hockerill Park Estate. Laid out from around 1890 by Sir Walter Gilbey on land he bought in 1868, with wide roads, tree lined avenues and grass verges, and mostly built out after his death in 1915. On Crescent Road, Avenue Road, Pine Grove, Thorn Grove, Gilbey Avenue and Warwick Road you are typically looking at an Edwardian or inter-war detached house standing in its own grounds, which means a long private supply pipe from the boundary and often an external stop tap a good distance from the front door.
Stortford Fields and St Michael’s Hurst. The new stock on the northern edge, part of a scheme of at least 2,679 homes running on to 2033. Modern layout, so the stopcock is normally in a service cupboard or utility area and clearly accessible.
Wherever it is, once we are in the house we will find it, free it off if it will free off, and show whoever else lives there how to use it.
What we actually get called out for here
Burst and leaking pipework. Failed compression joints, pinholes in copper, and frost splits.
Taps, valves and stopcocks. Drips, seized isolators, scaled up mixer cartridges and outside taps with the right backflow protection.
Toilets and cisterns. Running fills, failed flush valves, loose pans and leaking pan connectors.
Radiators and TRVs. Cold rads, stuck thermostatic heads, moving radiators for decorating, and balancing.
Appliance plumbing. Washing machines, dishwashers and fridge feeds, done with valves you can get at.
Cylinders and pressure. Immersion heaters, thermostats, unvented cylinder servicing and discharge pipework, and poor flow at outlets.
Emergencies. No water, a leak you cannot isolate, or a ceiling starting to bulge.
We take small jobs. A single tap or a single valve is still worth a visit.
Some of the hardest water in our whole patch
Affinity Water’s own supply zone report for the zone named Bishop Stortford, zone code AF018, gives a mean total hardness of 345 mg/l of calcium carbonate. That is Affinity’s published district figure, not a reading we have taken in your house. Affinity’s zone reports also note that almost all of its supplies are hard because of the natural geology of southern England.
345 mg/l puts this town at the top end of anywhere we work. Practically, that means:
Tap cartridges and shower valves scale up and start losing temperature control. Isolation valves seize in the open position and refuse to move when you need them. Immersion heaters build a coat of scale and fail early. Kettle elements and shower heads tell you the same story every few months.
We deal with it in two ways. Where a component is going to keep failing, we fit better quality parts rather than the cheapest available. Where a household has already replaced the same item two or three times, it is worth a proper conversation about scale protection on the incoming main.
Older pipework in a malting town
Bishop’s Stortford grew around a ford on the River Stort, and the Stort Navigation opening in 1769 turned it into the largest national supplier of brown malt to the London porter brewing industry by 1800. Listed malthouses on Hockerill Street are still standing. Buildings that have been through commercial use, conversion and residential fit out carry a mixture of pipework that no drawing exists for.
Lead supply pipes still appear on the oldest properties, normally as the incoming main. We renew the private section from the boundary in.
Old steel and iron on heating circuits in converted buildings corrodes internally and sheds into the system, which shows up as repeated pump failures and jammed valves.
Imperial copper in mid twentieth century work needs adaptors to meet metric fittings. We carry both sizes.
Microbore heating pipe from the 1970s and 1980s silts up faster than 15mm and is far less forgiving when it does.
Riverside property and the floodplain
The conservation area includes both banks of the Stort from Grange Paddocks southwards, together with the associated floodplain. Properties down there sit low, and low ground brings its own plumbing consequences. Cellars and lower ground floors are damper, which is hard on any metal pipework running through them. Boilers, pumps and cylinders sited at the lowest point of a house are the first things affected if water gets in. If you have anything vulnerable at low level, raising it or at least isolating it properly is money well spent.
The Stort is described locally as a chalk stream, and Thames Water has confirmed upgrades to Stortford Sewage Treatment Works at Jenkins Lane to improve the quality of treated effluent going into the surrounding waterways.
Conservation area work and Article 4
Article 4 Directions apply across the whole Bishop’s Stortford Conservation Area. Most of the controls only bite on elements visible from the public realm, but the control on installing, altering or replacing a chimney flue or pipe applies to every elevation. If your job involves a new flue or a change to an existing one, that needs permission from East Herts Council even at the back of the house.
Ordinary internal plumbing is not affected. But if the work touches the outside of the building we will say so before we start rather than after.
Frozen pipes and where they let go
Loft runs where insulation has been laid under the pipe instead of over and around it.
Garages, porches and outbuildings, unheated and usually carrying the outside tap feed.
Pipe chased into an external wall, common in later extensions, with almost nothing between the copper and the weather.
Outside taps with no internal isolator and no way to drain down.
If it has already frozen, turn the water off, keep flames away from it, and call. The split only shows once it thaws, so that gap is your chance to get the system isolated.

Frequently Asked Questions
How hard is the water in Bishop's Stortford?
Affinity Water’s published zone report for the Bishop Stortford zone, AF018, gives a mean total hardness of 345 mg/l of calcium carbonate. That is among the hardest figures anywhere we work, and it explains most of the seized valves and failed shower cartridges we see here.
My water pressure keeps dropping. Is that my pipework?
Not necessarily. Affinity Water has reported low pressure across CM23, including in July 2026 when it cited very high demand in hot weather and an issue at one of its pumping stations. Ask a neighbour first. If they are fine and you are not, the problem is on your side and we can trace it.
Who is responsible for the pipe from the road to my house?
You are, from the boundary inwards, including the cost of repairs. That matters most on the larger detached houses around Hockerill Park, where the private run from the boundary can be a long one.
Do you work inside the conservation area?
Yes. Internal plumbing is not restricted, but Article 4 Directions cover the whole conservation area and the control on chimney flues and pipes applies to all elevations, not just the ones you can see from the street. If a job involves a flue, that goes to East Herts Council first.
Are you more expensive at night or on a Sunday?
Out of hours work is charged at a different rate, and we tell you what it is before we leave the yard. Nothing is added once we are on site.
Do you take on small jobs?
Yes. One dripping tap, one seized isolation valve, one running toilet. Most of our regular customers started with a twenty minute job.
