    Hi All
    has any of you seen a type of compression valve that you can tighten over "live" copper pipes which have an insert that breaks into the existing pipe without leaking and has a compression fitting on to give you a T piece effect to connect another pipe to. So you can connect into an existing copper pipe to take off a new water supply to another place without cutting and jointing in a conventional T piece.
    I dont mean one to fit an isolating vavle below an item were one doesn,t exist like the Aladdin system but to T off a pipe easily .
    Any ideas gratefully accepted. Not sure if B and Q do one they call "compression isolating valve." Not sure if this is the same thing

    You can get self cutting isolation valves. They have a 15 mm compression fitting outlet ,so you can connect a 15 mm pipe to it .
    Not a fan of them though. The bit of copper that it cuts through ,ends up inside the existing pipe work and can cause flow problems downstream.
    Much better to plumb in a proper "T"
