This is a plumber's secret weapon that's now great for confident DIYers too. The Aladdin EasyFit valve lets you add a secondary isolation valve (stop tap) to a 15mm copper pipe WITHOUT turning off your water or draining the system. No more messing with pipe freezing kits! You clamp it onto the live, pressurised pipe, turn a key to cut through the pipe and create a seal simultaneously. It takes minutes and gives you a permanent, full-bore, WRAS-approved valve you can turn off whenever you need to work on a sink, toilet, or radiator. It's made from stainless steel and is incredibly robust. Perfect for creating an emergency shut-off if your main stopcock is seized, or for isolating parts of a system in a flat. The kit comes with everything you need. A brilliant, time-saving innovation for plumbing work.
