    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...

    Plastic and copper pipe sizing

    I am going to replace hot and cold 15mm copper pipe with a plastic system. The hot water is from a combi boiler and the cold water pipe is at mains pressure. The pipe lengths are about 10m each. Looking at the internal bore of 15mm plastic pipe, it’s much smaller than 15mm copper. To ensure...

    Ridgid 57018 C Type Copper Tube Cutter, 15-22mm

    I bought this Ridgid pipe slice type cutter over a month ago and it's been extensively used every day since then. It's attraction to me was that it cuts both 15mm and 22mm using only the one tool. However you pay a premium for this function, as my one cost me £35.77 which is more than you'd pay...

    15mm Soft Copper Pipe for above ground mains

    Hi, Are there any current regs prohibiting the use of 15mm and 22mm soft copper coils for an above ground domestic water supply?

    Where to get short, 8mm thread copper tails?

    This dam basin I’m fitting is for a particularly fussy customer. Its a corner, wall hung basin. He does not want to see the pipework, and I’m not putting the flexi tails that came with it connected in the wall like I’ve seen others do.
