A water meter service coupling facilitates removal and/or replacement of a water meter by allowing for expansion of the water service line upon disconnection of the water meter. One embodiment of the water meter service coupling includes a housing having first and second ends, an expansion piston having one end thereof slidably inserted into the first end of said housing for being slidably moved into and out of said housing, a retaining insert disposed at the outer end of said expansion piston, and a nut disposed about said retaining insert for coupling said expansion piston to a water meter, wherein the second end of said housing is coupled to a water service line and the water meter service coupling is installed in an expanded state so that upon disconnection from the water meter, the water meter service coupling may be retracted so as to allow for easy removal of the water meter.
