Service · Water pressure & hot water
Low pressure, airlocks, immersion heater faults, hot water cylinder issues, and Gas Safe registered boiler diagnostics. Whether the fault is water-side or boiler-side, we can get to the bottom of it.
Low pressure can come from several places: a partially closed valve somewhere in the system, scale build-up in older pipework (more common in the harder-water villages), a failing pressure-reducing valve, or simply a system that was never balanced correctly. We check the straightforward causes first, since replacing pipework is a last resort, not a first guess.
An airlock (water flows from one tap but not another, or a tap splutters and stops) is usually a trapped pocket of air in the pipework rather than a supply problem. Often clearable on site by running taps in the right sequence or bleeding the affected point; a recurring airlock in the same spot can point to a pipe run that needs a proper look.
Immersion heater not heating, tripping the electrics, or heating water that stays lukewarm: we can diagnose and replace the immersion element and thermostat, which is standard electrical-plumbing crossover work. Hot water cylinder issues (not holding temperature, leaking, or an ageing cylinder near end of life) we assess and advise honestly on repair versus replacement.
Being Gas Safe registered means we do not have to guess whether a fault is water-side or boiler-side before diagnosing it, or hand you off to someone else halfway through. See our boiler and gas safety page for the full scope of what that covers.
