Hello everyone,
Here is my situation (see photo): the pipe I want to connect my washing machine to has an inner diameter of just under 60mm (about 2.4 inches) and goes in about 2cm (0.8 inches) until a lip. I have found various HT pipes, but they all correspond to DN58, which is 58mm (2.3 inches). Would one of these fit securely, or is the 2cm (0.8 inches) lip too short? Furthermore, there is a slight draft coming from the pipe that has a very unpleasant smell, so I definitely want to use a surface-mounted trap, but this is only available in DN40.
Is there anyone here who can advise me on which pipes and adapters would fit to go from this DN58 pipe down to DN40? It is important to me that no odors can get into the hose.
Thanks and best regards,
Mary

To me, it looks like a rubber seal that already provides a tight fit. DN58 should fit snugly, a depth of 2cm (0.8 inches) is enough. The siphon acts as a trap to prevent odors, in case you’re worried your machine might start to smell. But that should hardly be necessary. As a temporary seal, I would use a freezer bag stuck on or over it.No, unfortunately, that is not a rubber seal; it is just as hard as plastic. I only cleaned the front part from old lubricant residue, which was quite wide. The front part was still wet when I took the photo, which is why it looks rubber-like.
What I definitely want to try now is a 90-degree DN58 to DN40 adapter, and on that, I’ll attach one of those surface-mounted odor traps vertically and screw the part to the wall using a piece of wood.
If anyone has a better idea, just share it.
