The soil pipe for my bathroom just goes straight down to the ground floor and if you look down it I can see water, I'm guessing some sort of sewer trap?
There is no venting on it at all. I was planning on using this
where it comes up through the upstairs floor and needs to turn 90 to enter the bathroom. Then continue the soil pipe up to the loft and fit an AAV to vent it all. The shower, bath and basin join into one 40mm pipe and join the stack with this:
Just below the branch.
If I can avoid having to run 110mm pipe up the corner of the bedroom it'd be good, I think I understood the regs that say the AAV must be higher that the highest point on the waste IE the basin overflow? Can I run HepVo traps on the basin, bath and shower and do away with the vent completely or does the soil stack need more venting than these can provide?
Thanks
Adam
