Painted 32mm waste

Have a leak on a solvent weld 32mm bathroom basin waste. The existing pipe has been painted. Does anyone have a recommendation on which will be easiest/work best for replacing the bad pipework and connecting to the painted bits - solvent weld, compression or push fit? Is it best to remove the paint first or does this action mean that the scratched area is worse than the paint?

Thanks for your help

replace the lot and repaint fresh. Its cheap enough. paint must be cleaned off pipe to be welded.

You have to remove all the paint whatever solution you choose, no easy way around it - or cut back to unpainted pipe. Best chance [1] of removing the paint is boiling water, if possible.

[1] Not much of a chance, its a bugger to get orf.

Does a steel scourer not work? Another option is caustic soda.

A piece of sandpaper wrapped around the pipe would take it off. Note that, if it's been painted correctly with just oil-based gloss topcoat, you won't get all the paint pigment off as it dissolves into the plastic surface.

Push fit won't connect to solvent weld: they're different sizes. So the choices are solvent weld or compression. Which is easier and more suitable? Either way I'd remove any bulky runs of paint. Emulsion scrapes off easily, oil-based is harder to shift. If you're going for solvent weld you should scrape the paint off back to the plastic. Doesn't have to be perfectly clean but you want the cement to bond the plastic, not the paint.
