Making a parallel branch on a soil stack

[Funkster]

Hi all, first post here and need some help!

I want to make up a 50mm parallel branch to join 40mm basin and bath wastes to a 100mm soil stack, as if I join them directly it's too close to the toilet connection. Just like it says in the regs.

What I would like to know is, does the J-shaped 50mm piece of the branch exist as a single unit anywhere, or do I have to make it up out of a bend, some 40mm branches, and lots of very short bits of 50mm pipe?

I've been searching for a single piece of the right shape but haven't found it yet, but maybe I'm just not looking in the right places...

Many thanks in advance for any advice!

j as in from waste pipe to soil we use 2 elbows to go down and across at a lower point in stack ?

Use swept elbows rather than standard ones.
