Hi everyone
I have a situation whereby Im looking to reuse an existing foul water drain to now take soil waste from a new upstairs bathroom at the foot of a new SVP but on exposing the drain today we found its only 6 inches from the crown to GL at falling to about 10 inches at the IC (crown) and incased in concrete for protection so its only shallow (that length of drain is about 8ft) this drainage was put in over 20 year ago and has BRegs approval as it was part of a rear extension, what Im wondering is what are my options to comply with BRegs as I cant go any or much deeper without lowering the IC?.
Any advice would be much appreciated
Cheers
