    I know you can use straps but can you not buy doubles on the same side ?

    Warning- It`s for underground connections and Kloor will go for her guns if you call her mate!

    Bossed connection not normally used underground. Would normally Tee off 110x110 and reduce to 40mm above ground. Please give further details of installation.

    Why can you not use two of the 110 x 40mm bosses joined together? They will meet up tight, similar to what you showed

    Yep - that shows you what I have in mind for the double connector

    PS my dad calls me "mate" all the time
    PPS the reason for not using 2 bosses is that I just trying to be tight - mind you may cost more to get a double :)

    Connections into vent not underground, post 5 misleading. Sink waste can boss onto vent up to 500mm above ground. Shower waste depends on branch to WC. 110mm Tee to WC with provision for 40mm boss at 90 degrees would suit if branch can be positioned low enough to give 1:40 fall from shower but best solution would be to have WC branch coming in at level of WC outlet, approx. 150mm above floor and use new back inlet gully, connected independently to main run, for shower and sink waste. Tell your plumber to start digging.

    A polypipe SWA43 gives you two boss inlets in the same plane on the same fitting.

    Costs way more than a pair of strap bosses though...

    Or alternatively use a soil manifold which may work out better

    I also never liked them. Handy if a boss fitting is a hard job to fit. They always look an add on and if the solvent has been plastered all over the joint makes them an eyesore.
