I am putting a 40mm pipe that takes the sink and washing machine through the kitchen wall and need to connect this to the foul drainage system.
I am in the lucky position of a new build house where the foul drain exiting the foundations is still visible. My question is whether I am obliged to connect in a gully in order to accept the waste or whether I can simply connect the 40mm pipe directly to the foul drain pipe using a strap on boss or other suitable connector (with rodding point at the highest bit?).
The second option seems neater and more maintenance free than the former but I can't seem to find a definitive 'OK' for using a direct connection. Ive looked at the relevant building regs ( http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADH_2002.pdf ) and section 1.8 seems to give a subtle hint that a direct connection is OK - but I am looking for a clearer statement.
We're on a septic tank in case that adds to the equation.
Thanks in advance for any expert knowledge out there.
