to connect 3/4 copper pipe to the flow meter without using the 1” PVC to 3/4” Copper Ball Valve reducer 25551LF, you need two U060LF 3/4” Copper to 1” SharkBite Copper fittings, two UIP4020 1-inch copper to 1-inch PVC Sharkbite fittings, a 6” Long piece of 1” copper tubing and a short ( 2-1/2 to 3” ) piece of copper tubing. The 6” piece of copper tubing goes on the backflow side of the flow meter and the shorter piece of copper tubing on the valve box side of the flow meter. This is the only way to mount the flow meter to 3/4” copper tubing without using the 25551LF Ball Valve 1” PVC to 3/4” copper adapter.
