    Hole in copper pipe, solder under floor, T coupling & protection

    I was stupid enough not to check the position of the pipes under the tiles when installing a toilet and drilled right through the center of a 16 mm copper water pipe. I exposed the pipe by removing a ~30cm section of the plastic sleeve and a ~10 cm section of the pipe around the hole. Several...

    I'm a kitchen fitter first and foremost, so occasionally encounter old pipes of varying sizes. From past experience I know how easy it is to misidentify old 3/4" copper pipe (apart from getting soaked when you get it wrong) and would like to know if there is a surefire way of telling it from...

    Is this copper soldering just ugly, problematic, or dangerous?

    Two pictures from a gas boiler install - is this dangerous, or just embarrassingly poor workmanship. What are the medium term implications of the joins like this? Do I need to get another plumber in to review and fix this? It is just shoddy but acceptable? Regards, Paul McGinnie

    Do I need a washer for blanking plug in a copper hot water cylinder?

    Hi all I'm blanking a couple of openings in a hot water cylinder. The Screwfix Flomasta 1" BSP plugs fit perfectly but no washer supplied or listed. Given that the element has a washer and everything else is a compression fitting I'm concerned these should have one. The alternative is PTFE...

    Connecting To Old 3/4" Copper Pipe That's Smaller Than Usual

    Hi, I'm trying to connect 3/4" copper to 22mm copper in an old house. However it appears that the 3/4" is actually slightly smaller (measured at 21.1mm) than it normally is. This means I've been unable to use the special 3/4 to 22mm compression fittings as the olive is just too loose...
