    We have removed a macerater from our ds loo and will be connecting with the inspection chamber in the garden.

    The setup currently looks like this. Pictures attached.

    I have notified BC but I haven’t been able to speak to anyone with it being Easter.

    The air admittance valve on the white pipe is higher than the flood level of the sink.

    Is this suitable?

    Can I connect the 32mm waste into the 110mm T or should I take it through the wall and connect with a boss?

    Yes, sounds good.

    Ok to put it into a boss in the branch inside. As long as you have enough fall.

    Cheers! I think I’ll put the sink waste through the wall and connect it with a strap boss to ensure there’s enough fall.
