Water supply, pressure & mains in Macclesfield
Pressure problems are diagnosed backwards: start at the boundary and work in. Your supplier has to deliver a minimum static pressure at the boundary stop tap, and if that is being met, the restriction is inside your property — an old supply pipe, a partly closed stopcock, a furred internal run, or a system that was designed around a loft tank.
The fix depends entirely on which of those it is, which is why a proper diagnosis comes before any talk of pumps. Fitting a booster to a house whose real problem is a 15mm lead supply pipe just makes an expensive noise.
Lead is worth singling out here. Homes built after 1970 will not have a lead supply pipe; homes built before it may, and central Macclesfield has a great deal of pre-1919 housing. Because the local water is soft and mildly plumbosolvent, lead matters more here than in hard-water areas. United Utilities will replace the section from your boundary to the main free of charge under their lead pipe scheme — the run inside your boundary is the homeowner's.

Low water pressure
Pressure and flow are different things, and most complaints are really about flow. Diagnosis works from the boundary inwards: confirm what the supplier is delivering, then look for the restriction inside — a partly closed stopcock, an old supply pipe, a furred internal run, or a system that was never designed for mains pressure.

Water hammer is the bang you hear when a valve closes quickly and a column of moving water is brought to an abrupt stop. It is not just noise — the shock loads joints and eventually causes leaks. The fixes are cheap: securing loose pipework, fitting arrestors, or reducing an excessive supply pressure.

Where incoming mains pressure is higher than the property needs, a pressure reducing valve brings it to a set level. That reduces water hammer, extends the life of every valve, cartridge and seal in the house, cuts the volume wasted at every outlet, and protects appliances rated to a maximum pressure.
Read more →Mains supply pipe replacement
The supply pipe runs from your boundary into the house, and it is yours. When it is old, undersized, lead or leaking, replacing it with 25mm blue MDPE transforms flow throughout the property — and United Utilities will replace their own section from the main to your boundary free of charge under their lead pipe scheme.
Read more →Booster pump & accumulator installation
Where the mains genuinely cannot deliver enough flow, the compliant solution is a break tank and booster set, or an accumulator that stores mains-pressure water for peak demand. Pumping directly from the mains is not permitted without the supplier's consent, because it draws pressure away from everyone else on the same main.

An under-sink filter with its own tap improves taste by removing chlorine and fine particulates. It is a comfort upgrade rather than a safety measure — the mains supply is already treated to drinking standard — and in a soft water area it is not doing anything about scale, because there is very little.
Read more →Discoloured or cloudy water
Cloudy water that clears from the bottom of the glass upwards is air, and it is harmless. Brown or orange water is usually disturbed iron sediment in the main after works or a burst nearby. Water that stays discoloured, or that tastes or smells wrong, should be reported to United Utilities before anything else.
