Wow all that from man with a name like Shokka. Gosh.

Oh *I* don't, and anyone who likes can come round and check out my Record

15/22mm one. As to hiring a floorstander, I've not needed to do so for some time.

On 28mm. A bigger fool than I thought possible.

Keep digging the hole. Springs for 28mm, hacksaws for plastic. Perhaps you don't realise the laughing stock you're making of yourself?

[IMM]

No you don't. It is clear you haven't a clue.

[Andy Hall]

Of course. It's so easy to thread through holes in joists under floorboards.......

[IMM]

You notch the joists. As long as the notch is no more than 1/5th deep then fine. If the replaced floor board is screwed back then this adds rigidity.

[IMM]

You can use just a copper bend and plastic pushfit fittings at either side of the bend.

[Dave Plowman (News)]

More use for the hacksaw?

Anyone who knows anything about pipework would agree the fewer joints the better. But then you obviously know nothing about pipework.

[Pete C]

LOL! Just bend it the other way as you take it off the coil, you don't need the strength of Atlas :)

If using a lot of it, it should be fairly easy to make up a jig for doing this out of some narrow rollers and a couple of bits of board..

cheers, Pete.

For a domestic floor, you would be outside of the building control guidance figures if you do....

Notches can be a maximum of 1/8th of the joists depth (or 32mm whichever is smaller), and may only occur within the first or last quarter of the total span.

So with a 200mm joist you can notch for 22mm pipe but not 28mm pipe.

If you drill a hole on the centre line of the joist then you can go up to 1/4 of he joist depth.

With chipboard flooring that will add all the structural integrity of a wheetabix....

Is there any preference between straight cut ( |_| ) or 'U' shape notches ?

[IMM]

Hacksaws have been known to cut copper pipe. Duh!

[IMM]

Makes no difference.

[Andy Hall]

I think you've lost the plot. The question was about plastic.

[Andy Hall]

What on earth for?

The whole thing can be done perfectly well in plastic as long as you read the instructions and use the right tools.

I saw some pipecutters today at £5. Would you like me to buy you one for Christmas?

[:::Jerry::::]

So has an axe !...

In message , Andy Hall writes

Or sure for tighter bends, but for general running of flexible plastic pipe (well Hep2O, which is my experience) there is no need for internal springs etc.

Best use the unipipe plastic system. When bent it stays there.

[Dave Plowman (News)]

So you've not got a proper copper tube cutter either? Is there no end to your meanness? Or would you like it explained how to use one?

[John Rumm]

Straight is simplest to cut, so you may as well go for that.
