Washer / dishwasher plumbing help

bobbybuttons

Hi , my daughter's just moved out and this is the plumbing in her new place   I'm presuming the waste for washing machine is attached to the pipe on the left somehow ?
She wants to add a dishwasher what pipework do we need to add or change so the waste can use the same pipe. Thanks

Double appliance trap is what you're after.

Thanks I thought that but there's another pipe coming into it from the right

Would this work adding it somewhere to the longer bit of pipe on the right ?

That would probably do the job, I would put it on the top of that pipe to ensure nothing can go back into the machine waste.  What does that pipe do / come from ? That black tape bodge at the back doesn't look too good !

I wonder if this would go in the gap left by pushing the adjustable waste fully down https://www.screwfix.com/p/mcalpine-v33s-compression-domestic-appliance-tee-piece-connector-white-40mm/4167p

Cheap and easy to use a twin spigot adapter to replace that single spigot.

I there a double spigot with the small thread - only seen them with the larger 1.5" thread.

I'm not sure which way the threads etc work to join the pipes but could I insert this here where the pipe is circled red instead of the bit that's there now ? The pipe on the right I think is for the second part of the sink , I'm not there to check

I wouldn't use one of these, they are very prone to blockages.
