Plumbers & electricians in Strood

Strood stands on the north west bank of the Medway at the river’s lowest bridging point, with marshy ground by the water in front of it and the chalk of the North Downs climbing behind. Watling Street came through first and the A2 still follows it. Yellow brick terraces with red brick detailing closed the gap between Strood and Frindsbury in the eighteen eighties, and after the First World War the council added houses on Steele Street and Frindsbury Hill. The larger wave came after the Second World War, filling in the triangle held between the A228, Watling Street and what is now the M2.

Wainscott sits further north, past Frindsbury, with farmland and the Chattenden woods around it rather than more streets. South of Strood the ground narrows and Cuxton and Halling string out along the west bank, chalk workings behind them, the Pilgrims Way climbing the downs above, and the Medway Valley railway threading between the two towards Maidstone.

So ME2 is not one kind of house. A boiler in Strood might sit in a Victorian terrace near the High Street, a nineteen thirties semi on the hill, a council built house from the fifties, or something newer on the old chalkpit at Medway Gate. What a lot of it shares is that it was first plumbed in an era with its own habits, and one of those habits is still causing trouble today.

Why galvanised pipe strangles the flow in an interwar Strood house

---

Galvanised steel was the standard pipe for water inside a British house from roughly the nineteen thirties until copper pushed it out in the sixties, which is the exact window in which Strood, Frindsbury and the streets running up the hill were built and then built on again. Steel on its own rusts, so the pipe was dipped in zinc to protect it, and for the first few decades that works. Then the zinc wears thin at the points where the water moves fastest, the steel underneath starts to rust, and the rust does not lift away in flakes. It grows inwards in hard mounded scale that builds layer on layer until the opening down the middle of a half inch pipe is no wider than a drinking straw. None of this shows on the outside. The pipe looks dull grey and perfectly sound, it holds pressure, a magnet sticks to it, and the only sign is that the house gets slower and slower. The hot side closes up first, because heat drives the reaction along faster, and because a cylinder pushes hot water out through the same tired steel every day of the year.

What people notice is the bath taking longer to fill than it used to, a shower that went weak so gradually nobody can say when, and brown or rusty water on the first draw of the morning that runs clear again after half a minute.

The usual guess is a tired boiler or the water board dropping the pressure, and a new boiler fitted onto old steel gives back exactly the dribble it gave before. The honest work is finding where the restriction sits before anything is bought. Often it is one length, the hot distribution off the cylinder or the riser feeding the bathroom, and renewing that single run in copper or plastic returns most of the flow without disturbing the rest of the house. Sometimes it is the whole distribution and a full repipe is the real answer. That is a judgement about your property rather than a rule. Nor is it always the pipework. A scaled mixer cartridge or a perished washer on a service valve can mimic the same fading flow at a single outlet, so one slow tap is a different question from a whole house going quiet. One thing to watch wherever old steel meets newer copper: the two metals in contact in water set up a galvanic cell and the steel corrodes faster at that joint, so those junctions want a brass or dielectric fitting rather than a direct connection.
