Hi,
I need to upgrade my 15mm Cold Water Mains pipework to 22mm. Under my sink where the stopcock is, it goes from the blue 25mm pipe (out of the concrete floor) through a 15mm stopcock and straight onto 15mm pipework.
2 Questions -
1) Do I need to replace the stopcock? With it being 15mm bore is it going to restrict my flow? I'm upgrading to a mains how water system so it's quite critical.
2) If I do have to replace, where is the next point of isolation? I can't see anywhere outside to isolate, it looks like it goes straight onto the street's mains...?
