Plumbers & electricians in Lenham and Harrietsham

The north of the district is a line of old villages at the foot of the chalk, on the ground where the springs break out. Hollingbourne, Harrietsham and Lenham are strung along that line with the Pilgrims' Way above them and the A20 and the railway below, and Lenham is where both the Great Stour and the River Len rise. It has held a market charter since the eleventh century and still has its square, its Grade I church and the tithe barn beside it, with ragstone and timber framed buildings around them, Victorian and interwar infill behind, and newer housing on the edges. Sandway, Warren Street, Platts Heath and Grafty Green are smaller again, a handful of homes and a lane each, and Hucking sits high on the downs above the lot of them.

South of the A20 the ground climbs to the greensand ridge and the villages perch along the top of it. Sutton Valence looks out over the Weald from the lip of the escarpment, with East Sutton and Ulcombe on the same ridge and the Greensand Way threading between them, while Chart Sutton, Langley and Kingswood are spread west. Boughton Monchelsea was quarry country, ragstone cut out of the hill until the last pit closed in 1960, and that stone is still in the garden walls and the older houses. Linton keeps its orchards, hop gardens and oasts, several converted into homes decades ago, while Coxheath, which grew on the old heath where army camps once stood, is far more built up than any of its neighbours.

Between all of that are lanes, farmyards and single dwellings a long way from anything. That scatter is the real character of the district, and it decides what the plumbing in a given property turns out to be.

Why a borehole behaves nothing like a water main

---

Not every property out here is on a water main. Between the villages there are farmhouses, cottages and converted barns that draw from a borehole, a well or a spring on their own land, and that changes what the plumbing is. A mains supply reaches the boundary with pressure already in it, and nothing on the site has to create that. A private supply creates its own. Behind the tap sits a source, usually a submersible pump hanging down the borehole, a storage tank, a pressure vessel and some form of treatment, and any of those parts can be why the water is behaving oddly. One pump lifts water into storage, a second pushes it round the house, and a switch reading pressure decides when each runs. The vessel holds a cushion of air behind a rubber diaphragm, so a small draw, a hand basin or a filling toilet, comes out of the cushion instead of starting the motor every time. When that cushion goes, because the diaphragm has split or the air charge has bled away, the pump has nothing to work against and begins hunting. You hear it kick in and cut out every few seconds while a tap runs, and the pressure at the spout rises and falls in time with it. In a house fed off the main, that pattern would point at the pipework. Here it points at the vessel, and a new tap or a new shower head will change none of it.

Treatment belongs to the system rather than being an extra bolted on top, because the quality of a private supply is the owner’s responsibility, not a water company’s. A sediment filter or an ultraviolet lamp works only while somebody changes the cartridge and the tube.

Two other things change what a property has to plan for. A power cut stops a private supply dead, because nothing moves without the pump, so the taps fail with the lights and how long the house keeps going depends entirely on what is already sitting in the storage tank. Some places out on the lanes keep a generator for exactly that reason. And where one source serves a farmhouse and two cottages, or a row of converted barns, the pipework and the electricity bill are shared and so is the argument. Whose pump it is, who pays to run it, and who may switch it off to change a filter are questions that tend to get settled after something has failed rather than before. What suits a particular property depends on the yield of the source, on how much storage exists and on how many households hang off it, which is why an honest answer starts at the plant and not at the tap. A written agreement about who maintains what, or a metered sub-supply, saves a great deal of bad feeling later.
