Is there any regulation,or practical reason I couldn't use an 87.5 degree swept tee for connecting a downstairs wc in to my existing drain,instead of 45 degree tees.

I am connect new wc and rainwater gully, it is end of line,therefore will use a universal adaptor on clay,then tee for wc (and stack) then tee for rain water,then 45 bend to rodding eye. there is a manhole 4 meters away further towards the main sewer.It would be easier if I can use 87.5 swept tee rather that 45 oblique tee,is there any issues with this?

It's my first post so be gentle,and thanx to all that contribute to this excellent forum

Cheers for taking the time to reply and confirming my question denso :)
Fine as long as you can access the run for rodding/jetting purposes. 99% of the time neither rods nor jetting hose will go round a bend (unless you dont want them to!) if the path straight ahead is clear.
