Common Questions
What is a reducing coupling? It’s a fitting that joins two pipes of different sizes in a straight line. The McAlpine ST28M joins 1 1/4 inch (32mm) to 1 1/2 inch (40mm) waste pipe.
What is a reducing coupling used for? It’s handy when a basin waste joins a larger bath or sink waste pipe, or when you’re replacing a section with a different size.
How do I fit a reducing coupler? Cut both pipes square, clean the ends, then push each pipe fully into its matching side. Make sure the smaller pipe goes into the 32mm end.
Which way should the waste flow? Normally the smaller pipe feeds into the larger one, so the flow goes from the 32mm side into the 40mm side.
What is the maker code for this coupler? It’s the McAlpine ST28M.
