We are buying a house and plan to add a rear extension. Went to view today to measure up and check for drains. The Foul and surface inspection chambers are right where the extension is going to go.
qu.1. I don't want to have to have access to inspection chambers in the extension (tiled kitchen floor) so I plan to relocate, what is the best way. I wondered if I could 45 degree and extend all pipes out the footing under a lintel and make a new chamber in the garden (see image). Is this OK, or is there a better way?
qu2. The surface water looks about 550mm below DPC level, but the foul looks very shallow, approx. 400mm below DPC. I was wondering how this would work with my concrete floor? As far as I can understand the regs, with 60mm insulation, the floor will be 400mm min thickness. If there a minimum distance below hardcore that the pipes can sit? or can they be touching, or within the hardcore layer (obviously protected with finer material).
Many thanks
