6.9.1 Check valve replacement
There are two check and pressure relief valves in the imeter module (one for each meter). The
valves are located at the top of the meter, in the meter dome, under removable cover plates.
The check and pressure relief valve is a non-serviceable part. Failure symptoms are computer
jump and crossflow. If a valve fails, replace it.
