"If you want a stopcock this one is the king. I know that if I need to isolate the water, I can do it without difficulty. No more guessing, checking and looking for a screwdriver. It's a tap and we all know how to use one. Worth every penny."
"Brought 3 of these 22mm stopcocks and a number of 15mm for a bathroom project. Of the 3 22mm stopcocks, 1 leaked from under the handle when installed. Had to buy a replacement. The 15mm version of these stopcocks were all okay. Moral of story, buy an extra one in case of leak and then send back the spare if all is okay."
