"Very easy to fit, and when I ordered it the staff at my local branch were very helpful with making sure it was exactly what I needed. Only installed it two days ago but as soon as I tightened the nuts by hand it was already stopping the water (couldn't fully isolate the supply). Don't forget the pipe inserts for the incoming 20mm pipe!"
"Only had this fitted for 2 days so can't really comment on the reliability. Easy to install and does what a tap should do. As a previous person commented you need the plastic inserts for the incoming pipe if not already fitted. This was new to me, here's an example: http://www.screwfix.com/p/floplast-pipe-inserts-20mm-pack-of-10/33270 Product code: 33270"
"i had to hunt around plumbase, selcos for a replacement stopcock for a post war house [ blue plastic water supply under sink] which was leaking badly and finally found the exact fit. dont forget to buy the plastic inserts for the incoming water supply pipe"
