I bought 3 SharkBite fittings for my flow meter install based on the posted instructions (using reducing coupling instead of ball valve). 2 of the U060LF reducing couplings for the reduction from the 1" copper pipe I had to add to the backflow side of the flow meter and the other for the valve side of the flow meter, since my existing piping is 3/4" . And a U020LF 1" coupling for the extra 1" copper pipe to be joined to the flow meter.
But I cant get the fittings on the flow meter ends! The outside diameter of the ends of the flow meter is too big and I cant fit the fittings over it. Thats for both the U020LF straight coupling and the U060LF reducing coupling. Whats going on and why are these instructions so misleading?
