Hi, I'm planning to move the washing machine to an en-suite where it will be close to a basin. So I'd like to get some advice on how to install water outlet and drainage. There's not that much room under the basin.

So I was wandering what would be the best fitting to install for cold water, whether a speedfit (but as you can see there's just a short end of the palstic pipe sticking out of the wall), or tee valve connected to the copper pipe above (but I doubt if I could do it there as it seems really cramped), or third option, if there was plastic tee valve I could place instead of the piece that is between right-angled grey part and white pipe. These are the dimensions of the grey middle part:



And what would be the best solution for water drainage? Should I replace the whole trap which would include drainage (at the minute, there's someting like this: https://www.screwfix.com/p/mcalpine-anti-syphon-bottle-trap-white-32mm/37314)? Or should I just cut the waste pipe and add an appliance trap like this one https://www.screwfix.com/p/floplast-appliance-trap-adaptor-white-40mm/11180 (but how would I connect it if there's no thread)?

Any addvice is very appriaceted and if you could recommend a specific product/part I could install, that would be fab. Thank you very much :-)

Hi dgross,
Scrap the grey bits and fit 15mm speedfit - T, washing machine valve and the inner bit of a pipe repair kit to extend the pipe coming out of the wall.
Waste wise you need to determine the waste size but either way search online for trap with appliance connector and choose the configuration which will fit.

Hi stoneyboy,

Thank you very much. I bought three speedfit part: T, valve and reducer. I just want to double check if it won't leak. I was surprised that T ends don't screw, so I couldn't tighten them, just push inside. I'm not sure if it's supposed to work this way. Thank you!

Hi dgross,
Yes it's interesting that the valves don't have a lock ring. Make sure you use inserts in the end of all pipes and that the release rings on the valve have room to move outwards (this is the locking action).
