I would like to install some end of the line waste pipe to the grey water outlet so I can attach either some flexi hose or rigid pipe.

This is the current outlet



The outer diameter is approximately 40mm
The threaded internal diameter is around 32mm.

Has anyone done anything similar ?

Thanks
 
Hi, yes I fitted a "barbed male spigot" to my outlet valve, then l fitted my flexible hose to that.
The thread will be "bsp" that's british standard pipe, go to a plumbers merchant, screwfix, toolstation etc, or ebay, once you know the size, possibly 1" or 1 1/4", see photo from ebay, hope it helps

Those ball valves generally have their size cast into the body, just below the handle. Clean the dirt off and see if you can find it and hopefully it's not on that tight side next to the mud guard ?
Going by the dimensions you've given (32mm id) that matches up with 1" BSP .
 
Thank you both
Very useful info
 
I bought one of these


And the Brucie Bonus is that the hose from a defunct carpet washer fits it perfectly, so no need to buy a waste hose
