Hi guys, I appreciate that similar questions may have been asked of this topic before but none seem to fit my circumstances.
We’re having a side and rear extension put in with a new kitchen across the back (drainage before the soil stack) and the bathroom in the corner where the extension turns and runs down the side of the house (ie After the soil stack). We are the last house at the top end of the foul water sewer so no one else runs into our property. The existing inspection chamber was where the new kitchen is so it has been picked out and brand new 4” pipe runs 8m from boundary, picks up the existing stack, carries on along the extension to a new inspection chamber out side the new bathroom.
But, for some reason, my builder decided to branch off this pipe approx 1m after the soil stack to run a separate line to the new toilet meaning that any basin, bath or shower waste will be discharged outside, into the main via a hopper but the toilet waste is separate and joins the main waste after about 3m run but is after the soil stack.
I’m worried that the system needs a vent after it and if so, I don’t know how this could be done because the toilet is on a different line from the others.
I hope this makes sense and that the existing stack will suffice for all the new drainage that will be up stream of it. Thanks.
