We have a downstairs toilet that is being decorated. We want to replace the small sink in there, but the stop-c*ck for water in the house is deranged (hidden in a very inaccessible place and caked up so its impossible to turn, about 5 cm off the ground (thanks prior botch-up artists!)). Whilst we debate how to resolve that issue, I stumbled across self-cutting taps (is that the right term?).
These seem to be ideal - we could put these on the pipes into the sink to turn off the water and then do the rest of the deed. But its very unclear from the images on the DIY web stores what/how this works. The suggestion is for outside garden pipes, but they look the right size for our pipes (15mm).
Do I (mis)understand...they will cut into the existing pipe, sealing it, allowing us to turn off the water, and then fit appropriate piping/tubing the other side to connect to the taps? Or is it a requirement the water be turned off before using them?
thanks
