I think he poo-pooed the idea... (cf Tin Pot)

Hi Martin,
A nice 'jack cut'saw from Screwfix will do your pipe - I got a 'petite' version to carry around with me for odd little things like this! 'A toolbox saw'! Stick a screwdriver blade in the slot once the blade has penetrated the outer surface of your boggle pipe.(It should be clean inside anyway - after all that rubbish lager drain cleaner you have employed these past decades!)
Something like a multi-tool would make your life simple - no spinning, just a reciprocal jaunt through plastic, metal, what have you...

Which brings me on to my thought; why are you replacing the pipe? If it is to get rid of the waste boss only, I would hacksaw off the fastener 'nib' (the whole boss section is likely to be solvent welded to the pipe anyway...) cut the protruding pipe back as tight as it will go and cobble up a bung - either using a rubber one or, probably easier, a solvent weld one and just liberally dob the adhesive round and fill that hole! Maybe I would think of cutting all the old plastic 'flush' preparing the surface with sandpaper and then solvent welding a nice 'patch' of clean uPVC pipe around the wound. Slow day at work...

I have that very saw! There are two reasons for attacking the pipe...(1) to get rid of the boss and (2) to re-route the copper pipe that runs parallel to it. I know it seems daft but there really is no alternative way of moving the copper one without making use of the temporary 18" gap that the chopped out soil pipe gives me.

It's my weekend adventure. The rest of the family will be away so I can run amok.

This is a cut on a piece of scrap pipe using the 125mm angle grinder and a diamond tipped masonry blade. It gives an extremely good finish.

What's wrong with Polypipe and a couple of push fit fittings onto copper tails etc? The 15mm poly could wind around the existing stack!

Yes, best suggestion above. A sharp new hand saw will deal with that plastic pipe in a couple of minutes even if it's only the tip of the blade.

Hand saws bind in the kerf when cutting plastic unless the workpiece is really firmly clamped. I can brace the vertical soil pipe in most directions, but it will flog around by a few millimetres when I'm attacking it. That's misery with a hand tool. I'll use the angle grinder tomorrow.

I can't get to the other end of the copper pipe that is jammed right into the corner behind the soil pipe. Believe me Martin, I have thought about this.


Anyway, I'm off to that grog establishment on Shepherds Bush Road for some much needed refreshment.

Edit: I'll leave getting sh*t-faced until tomorrow.

Use the joiners panel saw as suggested earlier. I always use one for cutting plastic soil pipe as it's easier to keep the ends square. Besides that how would you get an angle grinder into the corner?

As others have suggested, I have eighteen inches of vertical pipe to mercilessly butcher to get good access to the cut line with the angle grinder. I was amazed at how well the diamond blade worked on PVC.
I may well use some duct tape over my mouth to avoid unfortunate "splatter".

I know the pain. I didn't want to remove the loo from the soil pipe after 18 years. I was expecting all sorts of nasties. Nothing. Fitted a new connector, and I must admit I did a better job than the so called professionals. Will have taken me longer though.

My only worry is that the rubber seals on push-fit soil pipes (and waste pipes) don't last for ever. Most of the stuff in my house is well over thirty years old. If any of the existing system is faintly disturbed, I'll have some smelly/liquid leaks in inaccessible places. I'll probably smear some silicone mastic on them if they start...ahem...."weeping".

Everyone round to slowmo's house tomorrow, this will be one to tell the grand kids about the time you watched a man chop saw through his soil pipe.

Have you left yourself enough time to get a man in, if it all goes tits up?
