Any tips to get a drainage fall?

Better without the backdrop though. . 

Im with @PeterW, that example ( pic ) isn't great, you just don't bury an equal tee like that .

Yeah he didn't want any sort of backdrop. At least I have things in writing so if I do have any future issues, I can go back to them......

 

Just out of interest, why wouldn't you bury an equal T like that, is it not buried how ever you use one??

Just goes totally against the grain. Whenever you lay any type of waste pipework you need to look at it from a drain-rods point of view . Branches on the horizontal plain should be Y-branches with a 45 degree bend to rectify. 

That's a pic I posted elsewhere but if you flip that upside down, that's how I'd have done the same junction, with the waste falling into the 45 and then down instead of slamming into the vertical opposing wall of the equal tee. 

Tbh, I'd only ever do, and only ever have done the backdrop inside the chamber.

I see, so more of a gradual junction than a 90 degree

Yup . And a rod will follow it too. .
