Is there any fix for a leaking stopcock. It would appear that there should be a seal on the shaft which probably goes hard, because once you have turned the water off it always leaks when you turn it back on and you have to fuss around getting the tap in the right position so it makes a seal. It is the brass type so apart from having to replace it all the time is there a fix. Now this posting has come up I see that someone recommended that you can undo the gland nut and pack it with PFT tape but where do you use the PFT on the shaft or the thread. Is there FAQ section ont his site somewhere.
