Hi, just a quick question, I have ripped my bathroom out and need to move my basin, the waste goes from the soil pipe, to the basin to the bath, so it’s in inch and a half to the tee at the basin, then reduced down to inch and a quarter, to cut a long story short I have cut the inch and a half pipe near the soil pipe, I have solvent weld fittings, they fit on the pipe that I cut, would they not fit on the pipe if it was push fit pipe? I just don’t want a leak
