PLUMBING GUIDE
Guidance to help with planning, costs and finding the right Plumber for the job.
THE PROCESS EXPLAINED
Most combi boilers run best between 1 and 1.5 bar of pressure — too low and the heating cuts out, too high and the pressure relief valve can discharge. A plumber checking a heating fault will usually look at pressure, check for trapped air in radiators (bleeding), and check the pump and diverter valve before assuming a full boiler fault.
HOW IT WORKS
Buyers' solicitors sometimes ask about the age and condition of the boiler and any recent plumbing work, particularly if there's visible evidence of a past leak or repair. Keeping paperwork for any significant plumbing work — a new boiler, a bathroom refit, a burst pipe repair — makes this a much smoother conversation.
USEFUL TO KNOW
A full bathroom refit usually means removing the old suite, checking and often replacing the pipework behind it (since it's rarely accessible again once tiled over), first-fix plumbing before tiling, then second-fix (taps, shower, toilet cistern) once the room is finished. Waterproofing (tanking) around a shower area is a step worth confirming is included, not assumed.
HOW IT WORKS
Modern combi boilers display a fault code when something's wrong rather than just stopping — the exact meaning varies by manufacturer, but common causes behind a "no heat" code include low pressure, a faulty sensor, or an ignition fault. Note the code before calling a plumber; it speeds up diagnosis considerably.
HOW IT WORKS
On a new build or extension, "first fix" is running pipework through walls and floors before they're closed up; "second fix" is fitting the visible taps, radiators and appliances once decorating is done. Timing this with other trades on site matters — pipework needs to be pressure-tested before it's covered over, not after.
THE PROCESS EXPLAINED
Unlike electric underfloor heating, a water-based system runs off your boiler via a manifold and needs the floor buildup to accommodate the pipework — usually easier to fit during a renovation than retrofit into a finished floor. It's often paired with a lower-temperature heating setup than radiators use.
HOW IT WORKS
Materials — pipework, fittings, a new boiler or bathroom suite — are often a smaller share of a plumbing quote than labour, particularly for jobs involving lifting floors or chasing walls. If a quote looks unusually cheap, check whether it specifies the same brand/quality of fittings as a competing quote, not just a lower labour rate.
WORTH KNOWING
Slow-draining sinks are usually a local blockage (grease, hair, food waste) that a plumber can often clear with rodding or a drain snake. A blockage affecting multiple fixtures at once, or gurgling sounds from other drains, points to something further down the system — sometimes needing a drain camera survey rather than guesswork.
LOCAL GUIDE
Dorking is a Surrey market town of about 17,000 people located roughly 21 miles south‑west of London, in the RH4 postcode district and within Mole Valley district. The High Street runs along the northern face of a Lower Greensand outcrop and the town is bordered on three sides by the Surrey Hills National Landscape, close to Box Hill and Leith Hill. Archaeological evidence in the area ranges from Mesolithic to Bronze Age, and the town has a long history as a market centre; residential expansion accelerated with improved transport in the 18th and 19th centuries. For tradespeople, Dorking’s mix of historic centre buildings and later residential expansion means frequent demand for timber or stone repairs, roofing and sympathetic updates that respect the town’s protected landscape setting. Contractors should be prepared for conservation area constraints, the need to match period materials and to manage deliveries and scaffolding in narrow streets close to the High Street.
Working as a plumber in Dorking commonly involves properties across several eras: market‑town centre buildings with historic fabric and later Victorian/20th‑century terraces and suburban infill. That variety means tradespeople frequently deal with ageing pipework in older properties — sometimes copper that needs replacing or rearranging during bathroom and kitchen upgrades — and with first‑fix plumbing for loft conversions or extensions in newer streets. For water supply and sanitary work in Dorking it’s essential to use WRAS‑approved fittings so mains connections meet potable water standards, and any unvented cylinder installations must be carried out by someone with the G3 qualification because of the safety and regulatory implications.
Plumbers here also need to plan deliveries, access and waste removal where narrow High Street approaches and conservation constraints limit vehicle movement. Homeowners should ask prospective plumbers for WRAS documentation and, where applicable, G3 certification, plus references for period-property work such as matching pipe runs to existing timber floors or through stone walls. Expect quotes to itemise pipe replacement, access repairs and any repairs to flooring or plaster made necessary when replacing old pipes.
