Modern unvented hot water cylinders provide fantastic mains-pressure hot water to all your taps and showers. However, because they operate under high pressure, it is a legal requirement that they are only installed, serviced, or repaired by a plumber with a valid G3 Certification.At BC Plumbing, our G3 certified experts ensure your pressurised hot water system complies entirely with UK Building Regulations. This means your installation includes all the necessary safety mechanisms, such as temperature and pressure relief valves, expansion vessels, and proper discharge pipework.Living in hard water areas like Somerset and Wiltshire also means limescale can quickly impact your cylinder's efficiency. A professionally maintained, compliant system is your best defence against scale build-up and unexpected breakdowns.

A sudden drop in hot water pressure is one of the most common issues we attend to in the Frome area. This frustrating problem can stem from several different sources depending on the type of system you have installed.For traditional vented systems, it might be a problem with the cold water tank in your loft or an airlock in the pipework. In unvented systems, low pressure often points to a failing pressure reducing valve, a blocked line filter, or a mains water supply issue. Over time, limescale accumulation inside the cylinder or the thermostatic mixer valves can also severely restrict water flow.If you are experiencing weak shower pressure or trickling hot taps, do not put up with the inconvenience.
