    Leak on sink waste pipe

    A while ago I replaced a leaky, corroded sink trap. That all appears to be fine, I can't find any leaks with it, and everything under the sink appears to be consistently dry. The problem I have is that there appears to be a leak where the waste pipe out from the bottle trap meets the wall...

    Cutting copper pipe in a very tight space

    Hi everyone, I'm running copper pipework for my new bathroom and there's a spot about the isolation valve which is really tight because everything has to fit behind the wall until it can run under the bath and there wasn't much space as there's a sink there too. Made a silly mistake with the...

    Hide Pipe Recommendations

    What is the recommended way to conceal a 1.5M, 40mm shower waste pipe? We have 30mm gap behind the plasterboard which will be renewed. Would you chase the block 10mm or go into the concrete floor? What are the safety concerns of doing either? Thanks.

    Microbore pipe showing above radiator!!

    Newish house with radiators that have microbore pipe but on one of them the pipe is sticking up above the radiator which looks unsightly. Is it possible to push the excess pipe back into the wall? I'm worried about causing a leak.

    How much solder for 15mm pipe?

    About the diameter of a 22mm pipe

    WD40 in nut on water pipe - should I be worried?

    I needed to replace the braided water pipe for the hot tap as I was putting everything back together; I placed the female end into the copper pipe and before tightening the nut below it, I thought I'd add some WD40 into the nut just to make it easier to tighten. I then realised, given it's a...
