hi
while waiting for my building regs application for a number of jobs.
we need to install a new soil stack to serve new upstairs toilet and groundfloor toilet.
looking at installing a mini access chamber into existing clay pipe work as per photo attached.
issue for us is that the original clay pipe drain invert is only 420mm to ground level and once mini access chamber is installed the invert for the new soil stack pipe work at the chamber end would only be approx 310mm therefore at the rest bend end it would be close to surface and probably some of the rest bend would be above ground.
not sure if this would comply with building regs - as our application has only just gone in but wanted to gather some advice / suggestions as to if this would be ok or if we need to re think the position of any new access chamber further down the line.
obviously the current position is most suitable for accessing the existing drain.
flow of drain is from left to right in photo.
the left hand side of drain also supports a single gully outlet as single sewer/drain serves both foul water and rain water.
