    Hi folks.

    Is it OK for me to run 21.5mm boiler condense pipe into strap boss for 110mm upvc? No smells should come back in I'm assuming?

    Any suggestions where to buy adapters? Ideally all solvent weld as will be internal of property.

    Thanks very much

    Provided boiler has a built in trap, no smells.

    McAlpine R16 / R17 then suitable adaptor into soil

    No not gas safe but common sense prevails and says you wouldn't want to run to outside because of freezing temps.

    Basically the condense pipe runs through unaccessible roof on mum's extension and condense pipe was tapped into the 40mm bath waste pipe (also in the unaccessible roof space of extension)

    She stood on claw feet type bath which was wasn't screwed down to floor and inturn cracked the 21.5mm condense pipe. Thus condense water comes through the ceiling in kitchen. Boiler is in the loft.

    So my idea is chaps to tap into the condense before it goes through outer wall and tap a boss strap into the 110mm horizontal soil pipe.

    Sound OK?
