Soil stack - inserting two 135 degree bends

[theomegamale]

Hi

I just want to check this change doesn't fall foul of any building regs etc.

Do soil stacks need to be completely vertical? Can anyone take a look at the before/after pics and tell me whether or not my proposed amend is going to cause any problems with the council etc?

I'm basically putting two 135 degree bends into the soil stack (and there is another air vent right next to it running through a soil-size pipe which follows the same course which will be similarly rerouted) - doing this will allow me to site a coffin tank in the attic over a short concrete block wall for stability.

There are no inlets above where I propose to make my change so the "soil" should flow down just as easily after the change!

Excuse the crap drawing

no, wont make difference. at least your asking. some people dont care about altering drainage.
