Close the water service line before connecting the water meter to new, copper house lines. Close the main house water line to prevent back flow.
Examine the meter for arrows or other markings that indicate the direction of water flow.
Install a quick joint water meter coupling in the water meter with a pipe wrench. Tighten the water meter coupling only enough to seal the connection and do not use pipe sealant or Teflon tape.
Shove the copper pipe into the open end of the water meter coupling. Tighten the compression nut on the coupling with an adjustable wrench or an open end wrench.
Reopen the main water service line and check for leaks. Reopen the main house water line.
