Kitchen outflow pipe downsize All aspects of plumbing questions and answers, help, tips and information

[dpstoker]

Hi, I have a dishwasher that needs to move further back to fit flush with the other units, as is sticking out.
What's in the way is an outflow pipe with 50mm diameter. Replacing it with a 25mm pipe would do the trick.

Questions
1. Is this feasible?
2. Do I need to replace the whole pipe in the wall or can I get a converter (hoop shape) 50mm to 25mm?
3. Good places to buy a single simple elbow bend 25mm pipe?

Many thanks in advance
