Is it possible/ worth it to unglue fittings attached to blue piping?

[BeastOfBodmin]

We just moved a stack of blue piping, with various elbow and tap connectors glued on, from one place in the garden to another.

 

Is it possible, or even worth it, to unglue some of these parts for reuse?

A heat gun or gas torch on the inside of the pipe will soften things enough to work the pipe out.

 

I wouldn't trust the re-used fittings on much pressure but when needs must ...

For the cost of fittings is it worth the hassle, plus certainly quicker to use new ones.

I have managed to refit some parts after they came apart by using wirewool to get the old glue/cement off the used fittings and renewing the glue/cement to refit, but as has been said for the price of new not worth the bother unless its an emergency.

Blue PVC pipes (and other colours too) are neither glued nor cemented together. They are welded using a PVC solvent. If the joint has been done properly, it is virtually impossible to take it apart.

As has been said. Get new pipes, joints and fittings. They are dirt cheap and very easy to fit.

It’s absolutely possible, it is usually not too difficult.
 

The only time it makes sense is if you need the fitting and a new one will take too long to get.

 

Despite the contention of some, the parts are not bonded by more than the odd molecule so heat will release them. However the degree of heat is very close to the amount able to deform the fittings so you will probably deform a few before you get the feel for the minimum heat needed.

 

For amusement/education I have taken some apart, the pipe is always sacrificial.

 

NB the joints I took apart were always done correctly, so the contention that they are permanent and irreversible is incorrect.

 

The only absolutely permanently joined pipe is welded PP-R

I use a grinder and slowly put a few cuts through the glued joints, then break off with an old chisel or flat screwdriver.

No, not at all. All this blue Fittings regardless the size costs peanuts.
