Water supply, pressure and stopcocks
Mains inlet works, stopcock replacement, isolating valves on individual runs, pressure reducing valves and expansion vessels on unvented systems. West London stock — particularly Victorian and Edwardian conversions — often has original lead or galvanised sections we can identify and swap to copper or plastic barrier pipe.
Waste, traps and drainage inside the property
Sink, bath, shower and washing-machine wastes, bottle and P-traps, appliance stand-pipes, macerator support and internal soil branches. We coordinate with the drains team if the fault is below the trap — see our blocked drains page for external work.
Cylinders, tanks and hot water
Unvented cylinder installations by G3 qualified plumbers, vented (gravity) cylinder upgrades, expansion vessel checks, immersion swaps, temperature and pressure relief valve replacements. Manufacturer-approved parts, correct labelling and safe discharge routing.
Domestic vs commercial
For commercial premises — cafés, salons, offices and small units — we work around your trading hours where possible and quote around minimising downtime. Isolation, temporary supply, and out-of-hours scheduling are all part of a normal commercial quote.
Materials we work with
Copper (soldered and press-fit where appropriate), MLCP for concealed runs, WRAS-approved brass fittings, quality-grade PTFE and jointing compounds for compression joints, and manufacturer-specified parts on Vaillant, Worcester, Ideal and other mainstream boilers.
