    hi, so we had tried to fit an isolation valve into copper pipe that came close from the mains supply, but i'm not proud of it. we had to leave the mains water valve at half pressure or else the fittings would leak/pop off.

    Tap tails to 15mm copper

    Good morning gentlemen. Tomorrow I'm replacing the kitchen mixer tap with a new Chinese one (Cooke & Lewis Amsel) which has 300mm flexy tails with female ends. Because these are longer than the existing rigid tails, I'll be needing new connectors for the 15mm copper feeds which I'll be...

    risk from a copper pipe with little support?

    Hi everyone, Looking for some advice about whether there is any risk from a pipe in a flat I just moved into (not in UK). Under the kitchen sink, the cold water enters through a copper pipe that has been bent upwards in a weird shape so that it can reach the sink. They’ve done this because a...

    Hand made copper tap - swivel action?

    Hi everyone! I've just made a kitchen tap for a customer. She's delighted with it as it is but its wrecking my head that it doesn't swivel. I can't imagine a fitting that I could have soldered in that would give a water tight swivel action and equally as important, keeps that all copper look...

    Bending 15mm copper 180 degrees?

    I have a Draper 34212 lever bender. I know it isn't a Hilmor but I don't bend 3/4" much so it does the job. The one thing that is difficult is bending 180 degrees. Do you guys have any tips? Obviously I can do two 90 degree bends with a gap between but often I need a 180. I was thinking of...
