Toilet waste.

[Alltheones]

Is this legal for waste drainage? I’m struggling getting a branch off my toilet waste for the durgo. I was going to fit 2x T adapters on the small stack but there’s no where near enough room under the floor.
If I put a 4 way adapter on the stack I need 3 bends to get the toilet waste into it as I can’t twist the branch the right angle.

2nd pic you can see what is my sewer waste with the bag on it and inbetween the two joist the toilet pipe would be coming straight down.

I’m scratching my head with this.

is a 40mm rodding point enough in a 110mm waste pipe? I could fit it into one of the 40mm points in the T adapter.

then I could use some 110mm flexible underground pipe to get from the toilet to the T adapter then out the top of the T a bend then off to the durgo. My problem is it’s like 500mm to the toilet across and the same up so I don’t have room for multiple bends.
