Solvent weld - Mix ‘n’ match?

[smallsteve1]

I have Floplast waste pipe and need to feed into the soilstack. Due to space restrictions (internal wall built over the top!) it will be easier to use an offset reducer, but Floplast only manufacture (solvent weld) reducers with the entry point in the centre. Obviously other manufacturers do produce offset variants but I’m not sure whether it is a good idea to use them i.e. mix and match? Once fitted, this piping will be just about inaccessible.
Having looked at other postings, I am getting conflicting information about compatibility and would appreciate further opinion on the best way to go i.e. stick with Floplast or use any manufacturer’s (offset) reducer?

TIA.

I was forced a few times to mix and match and sometimes those fittings were loose or too tight.
However, none of the joints have failed so far that I know of and some have been there decades.

Solvent weld, as opposed to push fit, is pretty much interchangeable. Just check the pipe isn't too loose, once glued it will be fine.
