The LavaTap Radiator Valve Change Kit is an essential plumbing tool for servicing radiators in central heating systems. This kit enables you to change or service radiator valves without the need to drain the entire system. It features two precision-engineered rubber bungs that create a temporary vacuum seal on the pipework. By inserting these bungs into the exposed radiator valve inlets, the LavaTap kit safely isolates the radiator, preventing water leakage and minimizing disruption. The kit is compatible with standard 15mm and 22mm radiator pipe sizes, common in UK homes and commercial buildings. It is ideal for replacing thermostatic radiator valves (TRVs), lockshield valves, or applying central heating inhibitor. This tool is widely used by heating engineers, plumbers, and DIY enthusiasts. It can be used with radiator bleeding kits, pressure testers, or chemical dosing devices, making heating maintenance tasks more efficient. Each bung is constructed from durable, pressure-resistant rubber, ensuring reusability and long-term value. The LavaTap Radiator Valve Change Kit offers a cleaner, faster, and more efficient solution for radiator servicing without the hassle of draining the heating system.
