Spatial Separation - 7.3.5.6

[Mr_T_123]

I'm planning to replace my old clay building drain with 4" Green SDR 35.

After digging up my slab, I'm noticing that there are some sections (there are about 45' in total) where my water supply line is fastened to the clay pipe or comes close to the clay (it's in my trench I created). There is about a total of 10' or so where the water line is in my trench.

OBC 7.3.5.6 says I can have the water line in the trench if the building drain is pressure tested at 345 kpa (50psi).

Will the Green SDR 35 (non gasketed) that seems to be readily available hold 50psi? If not, what are some good alternatives?

I think I misread 7.3.5.6.

It seems like as long as my waterline has no joints or fittings (2b), which it doesn't, then I don't need the pressure test on the building drain.
