    Clean up pipes

    Hi Tony I think I've confused you slightly. I'm not sure what you mean by never install a 15mm pipe?? It's not a new water supply it's all existing. Why would you need more than 15mm for a kitchen sink?

    Clean up pipes

    Hi everyone, should be a straightforward question this... I've core drilled through a 500mm+ stone wall for new incoming water supply @ 15mm. Do I need to sleeve the pipe outside? Do I need to sleeve the pipe in the wall? Internally, the pipe goes in the concrete floor in places, and...

    Thanks everyone that helped me with this job. Sadly I was to stressed out over the job to take proper progress pictures. The photos don’t illustrate all the alterations, bedding of the pipes, DPM, etc. I went with ready mixed concrete in the end, it was more expensive this way but it...

    Thanks chaps I'm 50mm to far to the left but I can live with it, I didn't want the buggeration of bending the stack for the sake of that 50mm. Last but not least is the floor, I've got 0.90m3 of concrete to pour, what would be the best way to achieve this? I'm short of the 1m3 for ready...

    Thanks again Hugh, one minor irritation I've come across is can't seem to find brown in less than 3m lengths, which is really annoying because I've got a small car. Had loads of funny looks last time I was transporting 2 lengths of straight pipe in the car, 400mm of it was sticking out the...

    Bedding new inspection chamber

    Any suggestions on how to do this? Will be hard keeping the concrete from the couplings unless I knock up some formwork but will involve a lot of buggeration I can picture it now. To be clear, does the concrete only need to be around the sides and not underneath?
