Is 50mm push fit ok?

[cwr]

Hi folks

From browsing this forum it's fairly clear that for waste pipes buried in the floor and in ceiling voids 50mm solvent weld is the way to go.

However, I am seriously struggling to source any solvent weld pipe an fittings in NI (exception being screwfix abs pipe, some of which is described as overflow pipe, and a little pricey and limited in fittings available). All the local places only carry push fit, and mainland GB supplier don't want to know. Just spent some time putting in a large order with Plastics Express only for them to then cancel it 2 days later saying that they can not send out items longer than 2m! So, at least I can get the fittings, but not the pipe.

Now starting to wonder if push fit would be ok, there's going to be some buried in insulation under the screed, and in service voids under pre-cast slabs.

Thoughts?

How long are the waste runs? 40mm solvent weld should do the job in most cases and loads of pipes and fittings available from Screwfix.

Do local plumbers or builders merchants not stock it?

The four biggest builders merchants don't, and a couple of the larger plumbing suppliers don't either. Mustn't be what's done round these parts...

Up to 4m. Could use 40mm for most of it, just want to do a gd a job as possible.

Given the choice between 50mm push fit and 40mm solvent weld, what would be preferable?

Up to or over 3M you need to upsize with UK Bregs, so 50mm is required AFAIK.

I've avoided push-fit waste for over two decades, hate the stuff. Certainly not reliably enough to bury anywhere imo. Can you get someone you know here to box up stuff and post it to you?

Got this sorted. Plastics Express told me the brand is Aquaflow, so was able to source it elsewhere eventually and got the 50mm (10pk) from Toolstation, and some single lengths of 40mm and 3mm from eBay (not cheap, but Toolstation wouldn't deliver single lengths).
