pipe joining cement - removable?

[jambo000]

Hi all,

I have a few 50mm plastic waste pipes that i need to make a few adjustments to for my new bathroom. All the joints including the toilet waste are joined using the 'pipe cement' sealer, is there a way of removing this stuff other than cutting the joins out ?
Cheers,
Jim

I certainly am no expert here, only having done this a few times, but from what I have read, the joint generally is just as strong as the tube.

Therefore, yes, have to cut.

I've tried a heat gun before, and it lossens the glue....but there's also a real good chance of warping the pipe......may be better to cut and re-glue.

:iagree:
The solvent literally welds the plastic together

It's good when that happens... isn't it :2tsup:

(If only it was always like that....... )

Depends if you want to save the Pipe,
or the Fitting.
But yes,
generally they are WELDED!

I've seen my mate un-glue by setting them on fire. It's been awhile but I think he poured some white spirit over and in the fitting and lit it up. I guess it's the same principle of the heatgun trick.

Cut out what you need to and use sockets to join back on to the existing pipe. They're about $1.50 each, worth it I reckon.

If your wantin top save the fiiting you can cut the pipe just before the fitting, smear some glue around the inside of the pipe in the socket and light it ( an oxy set spark lighter works well nd keeps fingers away) after a while the inner bit ( the old pipe ) is soft enough to be levered out with an old screw driver. Probably much easier to do than explain.

I should note the fitting needs to be facing in a direction to have the flame coming out not into the fitting.

Why go to all the heart ache and bother when you can pick up a socket for bugger all, not to mention the time you'd save. I only burn fittings out if its absolutely necessary.

I asked the question not because i wanted to keep the fitting but to not have to cut into pipe that was just the right height. Anyway , i cut the pipe and i managed to get away with it.
Thanks for the replies...
