Got to plumb outlet from washing machine into open vertical length of 110mm plastic pipe at floor level. Any suggestions for best way of doing this? Presume I'll need a trap? Use 40mm stand pipe and u-bend? How best to join to 110mm and cap the 110 pipe?
 
Do these adapters work?

You say an open vertical pipe, can you be certain it’s not a vent pipe for the drains? Or is just a short piece of waste doing nothing, if so is it connected to anything?

These questions need to be thought of

Cheers
 
A photo at this point might be useful, to try and determine exactly what it is. If it’s open, then why? Was there one there before and you’re renewing?

Yes. It was put in byoriginal plumber at first fix and planned as washing machine outlet. Appreciate the warning though!

New extension. Pipe put in by original plumber with washing machine in mind. No photos sorry - too dark - but just looks like 75mm of 110 pipe coming out of floor@

One of these might be better as it’s above ground, but you will definitely need to trap it to stop smells.
