I'm trying to add some pipe work to what I thought must be a 50mm Solvent Weld type Tee piece. But when I measured the internal diameter of the tee piece it is actually 55mm and the 50mm pipe I have just rattles around inside. I thought that waste pipe only came in 50mm, is there such a thing as 55mm diameter pipe? So it will fit snug enough for the adhesive to bond the plastics together?
