METER MAINTENANCE
The only suggested maintenance is to annually remove the meter from the
water line and gently back flush the meter to remove particles that may
have been trapped by the strainer. Back flushing is running the water into
the meter from the outlet side instead of the normal flow direction. If some
unusual evidence of meter performance is observed during maintenance,
please contact the factory.
A broken tamperproof wire & seal indicates the meter has been
disassembled.

5. It is not recommended that the meter be run for long periods of JLP1000-G ¾" X 1" 50 GPM 25 GPM ¾ - 50 GPM
time at the maximum flow rating as excess wear will result and
the life of the meter will be reduced. JLP0750-L ⅝" X ¾" 83.28 LPM 45.42 LPM .95 - 83.28 LPM
