Hi all
How reliable are these self-cutting tap devices - the ones usually marketed for adding outside taps? I really could do to drain the hot water cylinder (partially) to remake an Essex flange joint that is leaking. There is a drain c*ck at the bottom of the cold feed to the tank, but it is inaccessible and leaks past the stem when in use. I was considering fitting the self cutting tap thingy in the vertical leg of the feed, a little above the existing drain. Granted, the tank could not be totally drained using this new take-off, but it would get me round the current predicament.
TIA
Phil
