Plumbers & electricians in Hoo Peninsula

The peninsula is a line of chalk, clay and sand hills with marshland wrapped the whole way round it, the Thames on one side, the Medway on the other, and the A228 doing most of the work as the only main road. Hoo St Werburgh is the big one, about fourteen hundred people at the end of the Victorian period and nearly nine thousand a century later, with Chattenden joined onto its western edge. Cliffe grew on Victorian cement money and the chalk quarries that paid for it are still sitting there, flooded. Cliffe Woods went up later and looks it. Cooling, St Mary Hoo and Stoke are tiny by comparison, a couple of hundred people between some of them, with a castle, a marsh church and a lot of open ground.

Higham sits at the far western end, nearer Gravesend than Rochester and inside Gravesham borough rather than Medway, which is the first thing that confuses anyone working out who to ring about what.

East of Hoo the building thins out fast. Allhallows was meant to be a resort with five thousand houses, a theatre and the largest swimming pool in the country, and the war ended that plan, leaving a big pub, a station that shut in the early nineteen sixties and a holiday park. Grain was rebuilt around an oil refinery that ran from the late forties to the early eighties. In between are working farms, grazing marsh, stable yards and a great many loose outbuildings.

Why collected rainwater has to stay on its own pipework out here

---

A rainwater harvesting system is four things and one rule. There is the collection side, which is roof area, gutters and a filter that keeps leaves and grit out of the store. There is the storage itself, usually a tank buried in the garden or standing in a barn, sized against roof area and rainfall rather than against optimism. There is a pump, because a buried tank delivers nothing on its own. And there is a mains top-up for the weeks when it does not rain, which on this peninsula is most of a dry summer. The rule is the part people get wrong. Harvested water is not drinking water and must never be able to reach the drinking water system, not through a shared length of pipe, not through a valve somebody left open, and not by being drawn backwards when pressure in the main drops. That is why the top-up is made through a physical air gap, an open fall of water into the tank with daylight between the mains outlet and the highest the stored water can ever sit, instead of a pipe screwed into the side of the tank with a non-return valve relied on to hold. A valve is a moving part, and moving parts fail open as readily as they fail shut. A gap cannot fail at all.

What it looks like from inside the house is rarely a burst. It is a pump starting and stopping every few seconds when the yard tap opens, a top-up quietly running on mains water since March, or an outside tap nobody can account for.

On an older place the commonest finding is a pipe with nothing written on it and nobody left who knows where it goes, so putting things right is mostly identification and electrics. Every non-potable pipe, outlet and appliance connection wants marking, at the tank, at the pump, at each tap, and again wherever a run comes back out of the ground, so that the next person to open a wall or a chamber cannot join the wrong two things together. Labels belong on a cistern lid and a washing machine inlet as much as on a garden tap. The pump needs power it can depend on, which means a fixed circuit run out to the building, an enclosure that suits a damp cold barn, and cable that survives being buried or clipped across a yard. Whether any of it is worth doing is a per-property question, and for an ordinary house the honest answer is often no. For a stable yard washed down twice a day, a nursery, or a smallholding with troughs to fill, the arithmetic changes, and that is the version we come across on the peninsula.
