    Help identifying what these pipes are for

    Hello all, I was clearing out my first floor bedroom built-in cabinet and saw these pipework in the image. I'm not 100% sure what they are for. The only thing I can think of it for the central heating system as the pipes seem to go quite high (quite a but higher than radiators in my house)...

    How much joist can be cut out fo CH pipes

    Hi all, Heating engineer has curved 15mm ch pipes where the wall meets the ceiling instead of notching the joist further and putting them at a 90 degree angle so completely hidden when ceiling is boarded and wall bonded then plastered. He explained that he couldn't notch out the joist anymore...

    Drain hot water pipes

    Hi, I'm going to fit a shower pump to the hot water pipe highlighted in the attached image. Just wanted to double-check my thinking: there's a valve on the cold feed to the cylinder so if I shut that off and run a downstairs hot tap until nothing comes out is that enough to empty the pipe I'm...

    Central Heating Pipes

    Hi all, Earlier today I was trying to get a few floorboards up to get access and one of the 15mm pipes came out of its brass tee connector with the ensuing wet face and mad panic that a bar of water can give you. I popped a bucket under the fountain (it was pointing ceiling way) and ran down...

    High pitched note from mains water pipes

    I have a flat in a 1920s UK block. The mains water feeds ~40 flats, of which I am one. There is no local boiler, though there is a communal one for the whole building. Recently, always at night, the mains water pipes have started to vibrate at a high frequency - emitting a "singing" note ...

    Can I reuse these pipes or will I need new ones?

    I want to move these two 22m water pipes closer to the wall - the pipes were never chased into the plaster but fitted onto the wall. Now the plaster has been moved I was thinking of moving the pipes nearer to the brick and then covering with plasterboard. Will I be able to reuse these pipes or...

    Noisy pipes on cold main

    I am perilously close to losing my mind - so any help appreciated! About a month ago a vibrating sound started on our cold mains (copper pipes). This noise will often go on for 12-24 hours, always a loud rumbling sound that you can feel in the pipes. I am in a maisonette, and believe the cold...

    Hi again. Builder will soon be laying the floor in our new extension. It's currently a concrete slab and he's going to lay a thin (a few mm) of sand on this to level out any imperfections, lay 80mm insulation (I guess will be 'Celotex' type stuff) and then chipboard flooring on top. I need to...

    Plumbing Newbie - Replacing Copper Pipes

    We've not yet ruled out getting a plumber in but this seems a small job, suitable for diy'er? We have 1930's house and quite old plumbing, hopefully not that old. The pics should help show the task in hand. It's pipework under the sink, hot and cold feeding up to the basin with spurs off for...

    Copper pipes or plastic pipes?

    Hi! I have to change all the plumbing in my mother's house. She lives in an old building that is approximately 100 years old and there wasn't much done to keep it up to date. My question is: do I use plastic or copper pipes?

    Push fit soil pipes..

    Does it matter if they aren’t fully inserted, as long as they go past sealing ring? I cut a bit of pipe 1-2cm too short and can’t get it out the other side to change!
