40mm waste to 110 horizontal soil

[Eddm87]

Hi.
Just about to put joists in new part of the house but got the basin and shower waste exactly where I need to go. (Ignore the top waste in the photo)

By far the easiest way for me to change them round is to drop them straight down and use two strap bosses to go into the top of the horizontal 110 pipe.
I’m not worried about drains blocking and backing up as there are bits on the ground floor that will show me that.
If I need to I will add hepvo valves but I don’t expect the water to get pulled out the trap.
Mainly wondering if it’s against the regs??

Thanks in advance.

Edd

Sack the groundworker - seriously it will not pass BC like that it needs to be clipping distance off the wall secured correctly, have rodding access at the base where it enters the ground, the 2 branches can be connected into 2 boss pipe adaptors then take the stack up above the gutter with a balloon grate on top .

From my reading of this its all temporary, yes because few aspects of this work will satisfy Building Control and more importantly and survey by a future purchaser. centralheatking
