pipe-fitting disasemmbly after solvent glueing?


so what is the easiest way to remove a pipe from a fitting that has been glued in. i trying to remove a fitting from a pipe but with little success so i am looking into plan b which is cutting the pipe flush with the fitting and then removing the pipe from the inside of the fitting. i am thinking hand hack sawing the pipe in segments and prying off-out with a sharp chisel or scredriver...... didnt know if any solvents would loosen the bond....

Are you just funnin gw? LOL

Seriously, I'm just a newbie but I don't think there is any way in the world to do what you want. PVC and CPVC (I think ABS also, not sure) can never be separated after the cement is put in the fitting and the pipe inserted.

My understanding is the pipe and the fitting then become one, a very strong molecular bond as strong as the pipe itself. I think you just have to throw that stuff away and start again.

But I'm just a newbie I'm sure the pros will give you the correct information.

Good luck!

no- not funnin unfortunately. i am hoping that maybe this is possible to a small level of certainty...... the connection needed to be basically fitting to fitting to work and now needs to be removed and corrected and there isnt enough room for a coupling........ heres to wishfull thinking!

gw I'm a newbie as I said. But there are pvc repair couplings. I never used one but maybe they would help.

I think the way they work is that they are telescoping and allow you to cut out a section and replace it without tearing out more of your installation. At least that's how I think they work. Maybe one would help?

Good luck!

agoodboy is correct. "Glue" is a little bit of a misnomer. You are not really gluing or cementing the PVC pieces together, therefore there is no glue or cement to break through or dissolve.

When connecting PVC, you are essentially welding the pieces together. The "glue" is really a solvent that melts or dissolves the PVC. The melted areas of the PVC flow together (at the microscopic level). Over time, the solvent evaporates and you're left with what is essentially a solid piece of PVC.

Imagine melting the ends of 2 candles, shoving them together and holding them until they harden. That's sort of what you've done.

I've never used the Ram Bit but I like the idea. Good luck.

Yeah, its a solvent molecular weld with Tetrahydrafuran (THF) The bits that cut out the core look like they will work, but you better have a serious drill like a Hole Hawg or a Milwaukee right angle with the anti torque handles. Those bits will burn up a home and garden drill in a new york minute, and break your wrist in the bargain!

It would be cheaper to redo it if you can.

Disassembly, I do not know! But if you have to cut and remove pipe from fitting. I just had really good luck using a heat gun.

PVC Toilet flange replacement options

I do not know if I got lucky with this or it will work all the time? If you try it please post your results.

You can peel the hub of a joint if your very careful. These young uns did not plumb before Ram bits.

Take a straight hack saw blade and cut the pipe in the hub several places bake sure you do not cut the hub but you must completely penetrate the pipe in the hub.. Then use a flat blade screw driver and a hammer carefully place the blade of the screw driver between the hub and the pipe pound it in and the first cut piece should pop out if cut right. Continue to do the same for the rest.

I use to do it this way too. But since ABS went cell core (very little PVC used here) It just tears in layers and next to impossible to clean out
So it's ram bits and a cordless drill for me.
i'd buy the other kind as they're better built but i've got the ram bit set already

I would use a ram bit today also less time consuming and time is money as they say. Just inspect plumbing any more I'm actually banned from working in the trade because of conflict of interest issues.
