    Hi All.

    I'm attempting some plumbing in my downstairs loo and i need some advice on how best to connect in to existing Galvanised pipe. Ideally i want a 15mm feed for the sink and toilet but will need to add a T-piece. Are there compression fittings for this type of job or will i need to cut new threads onto the existing pipe?

    I've attached a shot of my proposal.

    Thanks in advance.

    You would have to cut out a section of pipe and repair with copper or threaded galv pipe.
    Is it defiantly the hot and cold?
    What’s the copper on the left?

    So the top blue pipe is a cold water pipe. The bottom pipe is a gas feed into the kitchen. No hot water feed. I don't want to thread if possible because access is tight against the wall so getting a die in there will be a right PITA.

    Can you solder onto Galvanised pipe? I thought it wasn't a good idea?

    Thanks

    It’s not a good idea. You could cut the pipe, unthread the cold pipe at one of the elbows on the right then renew the run in copper using a male iron?

    It's not ideal but i was wondering if i could simply cut into the copper section of the pipe and run the feed back to the sink from there perhaps? That would mitigate having to faff with the Galvanised section. Not pretty but ok for DIY? Will all be boxed in to.

    Which bit is copper? It’s all blue it’s very hard to distinguish

    Yeah, previous owner painted it all. Anyways, copper starts just to the right of my second drawing. There's about a foot of copper before it bends 90°

    That's the plan! Copper where my red bit taps in.

    Don’t mess with that. Cut into this copper instead

    Was pointing it out to @Riley@Riley mate but gave my opinion at the same time. Sorry. Didn’t mean to steal your thunder.
