Passing pipes under floors

[mutley racers]

Hi guys. Just wanting to know how you lot pass your pipes under the floor boards?

Do you clip them to the sides of the beams? Or put noggins in?

Do you take the floor boards up at certain distances? What about if you need to run a 22mm pipe and notch but the beams are 180mm thick?

Also, do you take up 3 floorboards in one area to be able to pass the pipes in in a decent length?

Looking forward to all your advice

Regards

Mutley

If the joists run the right way I take up 3 boards and slide down the pipe with tape over the end

Otherwise take up the boards where the pipes need to go, notch the board using a circular saw and a hammer

or use 10mm and thread it through, can save getting up a lot of boards.

180mm is good for a joist some are only 100mm.

sometimes you can drill a hole through the outside wall and feed your pipes in then jump down and position them

Great tip, never thought of that, made my day. Thanks.

Ripping up floor boards, ok if they've been picked up before, I used to use a ripsaw but use a fein multitool now, much tidier and less chance of cutting cable etc, you can only notch top of joist by 0.8 x depth in the right area too, hand saw and chisel for me. Cable rods or wires sometimes help esp with plastic pipe or microbore.

Thanks for all the advice guys. It all does really help. Had to lift up a few floorboards the other day which were all tongue and groove. Lucky i had my little bosch multi tool. It would have been a mission otherwise. Only problem is is that the 10v batteries dont last long at all. I debated whether to get the fein corded one or the bosch. oh well. It is still a great tool.

Cheers

Hmm!

Expensive way to do things. Toolstation sell an electricians floorboard chisel and lifter for about £7, probably just as quick.

Err! A joiner once told us "Don't pull the board up straight away, punch the nails through into the joists!"

Well I did and it worked, except when I went downstairs, the plaster over the plate nails holding the plaster board to the ceiling, had dropped off here and there.

So a partly spotted ceiling resulted in that one and it looked horrible.

So bear it in mind if you are lifting boards.

Incidentally you I think you can get a cross cut blade for a circular saw as well as a rip. Its got finer and more teeth to the inch, so you should get a finer cut.

Thanks Bernie. I remember someone telling me about being careful with the nail punch while up stairs. So i have been pretty cautious.

I have just been using a wood chisel and hammer to lift the boards with
those electricians flooring chisels are long.

Have been postponing getting one since i started plumbing.

I've found this... only in the USA though..! anyone come across it before? there's loads of videos on you tube about it... NailJack Pro looks like a good piece of kit. It'll costs about £30 with the P&P though, so maybe worthwhile buying a few & hawking the rest on ebay. Any thoughts?
