Yep the far left pipe has a T that you just out of shot in the picture of the pipes under the work surface
This leads to the lowest connection on the above picture, and connects to the blue pipe
The blue pipe reaches a T, one side goes to the Taps on the sink and th other leads behind the...
So the pipe from the far left hand side has a T that goes under my sink and leads to this
The pipe with the stopcock on the right hand side of the boiler leads to a grey hose that is connected to the back of my washing machine?
Sorry I feel like there's something I'm just not getting...
The grey pipe leads to my washing machine and leads to the pipe to the right of the pipe with te black stopcock
The pipe with the red valve in this image leads to the pipe yo the left of the stopcock
So is this something the engineer hasn't installed? There look like there's a space for a connection between two pipes (the pipe with the yellow connection and the one to the right of it) but one end is connected to my washing machine?
Thanks for your help!
