    So, during winterizing of my fresh water plumbing system it seems that the coupling (white plastic spin knob) from the blue tube to hot water heater is stripped. Anyone know how to replace it so I can make a tight connection? Those tubes are stiff and that plastic knurled piece's threads are NOT catching no matter how much I try. Thanks IMG_4352.JPG

    Just to double check, before you buy and replace anything, take that short nipple right next door (in the pic) and see if it will screw in. Other than that, good find by Jim!
