"As a plumber I've used loads of these when fitting outside taps. They are well constructed from brass and do the job equally as well as similar more expensive products. I don't think you could ask for more from a wall plate elbow and I would recommend them."
"Fine backplate for replacing my old all-in-one outside tap that was dripping. Should only need to replace the tap in future if it dies and not mess with the pipe connection. Needed a washer between it and the £6.99 tap also from Screwfix. Can't see any reason to buy the dearer branded versions."
