L and L Plumbing and Heatings specialise in routine servicing for unvented hot water cylinders — also called mains-pressure cylinders — installed in houses, bungalows and flats across Bournemouth, Ringwood and Fordingbridge. A proper service keeps the expansion vessel correctly charged, confirms pressure relief and safety valves work, and checks immersion heaters, thermostats and discharge routing. These checks reduce the risk of leaks, scalding and premature component failure.
Our unvented cylinder service includes visual inspection, pressure and expansion vessel checks, manual operation tests of the pressure relief valve, thermostat verification and a full written service report. Where parts are worn or unsafe we advise on replacement options and can carry out repairs to preserve manufacturer warranties.
