I need to install a clothes washing machine in the bathroom and I have a problem to solve.
The drain hose of the washing machine is 25 mm in diameter on the exterior, made from a soft rubber material - see image A, while the drain is 32 mm in diameter internally made from hard plastic - see image B.
How do I connect them? Is there some piece that goes in between I can buy? Do I need to cut the head of the drain hose and replace it with something else?
