We will be running a new 110mm drain pipe in a 0.8 metre deep trench to the nearest inspection chamber. The inspection chamber is just over 1.5 metres deep with existing clay pipes entering it.
Can the new drain pipe enter the inspection chamber 1 metre below ground (and 0.5 metres above the bottom of the chamber)? i.e. the waste water will fall 0.5 metres into the bottom of the chamber.
Or does the waste need to run just above the existing chamber 'floor'?
