A Y Piece is the best way for combining waste streams. Unlike a 'T' there is less likelihood of blockage, salt buildup does not degrade performance and the flow does not back up into the non-flowing branch.
Y Pieces are available in a variety of sizes to allow 19mm and 38mm drain hoses to branch into one line. Manufactured in Glass Reinforced Nylon 6 Polymer, they are extremely tough and will handle both hot and cold water.
