Is all sewer/drain piping push fit? Fitting a Tee

OfflerCrocGod

I'm looking to fit a 110mm Tee into a storm water pipe under a concrete path ( https://imgur.com/a/o7P7RmM ). The only fittings I can find all appear to be push fit ones, solvent weld ones don't seem to be easily available. Is that because storm drains are not under pressure so there is no different in performance/leakage probability? Are push fittings the industry standard?

I guess the fact the pipe is angled downwards won't have any effect on the repair slip coupling ( https://www.topline.ie/plumbing-heating/plumbing/drainage-sewer/sewer-fittings/wavin/u-drain/premium-pvc-repair-collar-110mm ) slipping off? Is a file still the best, generally available tool to chamfer the piping?

I'm basically looking to follow this video here https://www.youtube.com/watch?v=4CWtom0IFmQ I guess that's all reasonable? I was just going to use a standard silicon spray from Woodies.

Push fit is the standard and are more than good enough. Plenty pressure pipe systems using push fit also.
You could file the pipe or if you can get at it, quickly run a grinder around the edge.
Also slip collar won't move once put into position.

Thanks, good to get some confirmation.

Take the video as a general guide.
If fitting a Tee branch as demonstrated, I would only use the T and the slip socket.
Secondly I would cut the pipes so that there would be a bit less of a gap between the plain end of the T and the pipe.
Also where you make the joint, ensure correct and adequate support and chamfering is a must and lube (even washing up liquid) will make your job so much easier.

Great idea, I didn't think of that, I was going to buy this Y branch which has a push fit fitting in all endpoints but maybe one like in the video would be easier as I'd have to cut less of the pipe thus dig out less sub-base and then as you say just push the slip socket up to join the two. I'm going to use this https://www.woodies.ie/holts-silicone-spray-1115342 for lubricating the pipes and https://www.diy.com/departments/floplast-pipe-clip-dia-110mm/80964_BQ.prd to mark the pipe for cutting. I'll have a look at my local builders providers for a Y branch with only 2 push fit sockets, thanks for the idea.

Actually I've just realized a Y branch is probably not suitable as the pipe is angled up so the joining pipe will end up going too high for a long run. It'll have to be this ~90 degree junction that I'll need to install. Excellent I think I have a good idea what to do, thanks K.Flyer and mickdw for the help.

Don't waste your money on the spray, washing liquid will do fine.
The clamp will work fine as a guide, only a few euro in your local building / plumbing suppliers.
For cutting, you might find it quicker and easier to use a standard wood saw.
