Plumbing question here: I need to fit an american fridge freezer to cold water supply it has a 22mm female fitting the pipe I need to fit it to is a 15mm male or slip the connection to the dish washer. I cannot seem to find the right fitting please help! Kind regards john

American fridges come with 1/4" O.D. compression fittings which can usually easily be adapted too...

22mm is 0.86"
15mm is 0.59"

That suggests that you need to go from 3/4" to 1/2" and any local PLUMBING supply store should have parts readily available for this transition!
