"Flexi tap connectors seem to have been with us forever, but in reality it's quite a recent innovation, which allows a compression connection from a supply pipe to the outlet, even under the most winding of paths, without the previous hassle of bending, soldering, swearing and a pile of knackered copper pipe. It's true that once youve seen one you've seen them all. It's also true that they're much of a muchness. Reliability and construction seem standard, I've never had one fail. What isn't standard however is the PRICE. Here Screwfix score big time. If you don't believe me, buy them elsewhere..and see your costs soar."
