I. GENERAL REQUIREMENTS FOR A WATER METER
INSTALLATION
A. Important considerations to obtain a professional meter
installation.
1. A service line, valves, connections and meter must be water-
tight.
2. Provide an upstream shut-off valve of high quality and with low
pressure drop.
3. The meter must be installed horizontally in the line with the
registration upright, to obtain optimum performance.
4. The meter is easily accessible for service and inspection.
5. The meter is easily read at the installation.
6. The meter and service should be protected against frost,
flooding, damage and tampering.
7. The service and meter installation shall not be an obstacle or
hazard to the customer or interfere with public safety.
B. The meter should be transported, installed, and protected with
care.
C. Special fittings and accessories are available to provide easier
meter installation.
1. Plastic swivel connections for a meter are available from
Badger to compensate for minor service pipe and setting misalignment
for a 5/8", 3/4", and 1" meter.
2. Metal meter setters, resetters, horns and meter yokes are
available for holding the service pipe in proper alignment to the meter
and laying length spacing. The metal setters and meter yokes can
provide an electric continuity to protect meters and consumers from
dangerous electrical shock.
3. Cast iron or bronze companion flanges are available for a
1 1/2" and 2" meter.
D. A meter may be installed indoors or outdoors. Where meters
are installed outdoors, they are usually located in a meter box.
When installed, the meter box should have a two to three inch
clearance around the meter to avoid damage or strain to the
service piping, meter, or the meter box should the box settle after
installation.
The service pipe entering and exiting the meter box should be properly
bedded to insure that it is not axially misaligned and lays evenly on the
bottom of the pipe trench. The placement of the backfill material to
cover the service pipe should be done carefully to insure that pipe
alignment is maintained and the service pipe will not be damaged by
eventual ground shifts.
E. Indoor meter settings may be located in basements, crawl
spaces, utility rooms, or in a garage.
Indoor settings must be checked for electrical continuity through the
service pipe (provided the pipe is metallic) before a meter is removed
for service or replaced as a precautionary measure. The AWWA policy
states service pipes are not to be used as an electrical ground. Check
your local codes and practices for your community. A permanent
ground strap or metal setter which provides electrical continuity must
be used if electrical grounding to water services is used in your
community.
Water dripping on the floor is undesirable. The meter installation should
include a valve just downstream from the meter to prevent damage to
the floor during meter servicing or removal from the line.
F. Services, especially a water meter, should be protected from
freezing. The amount of earth covering a service line must be
adequate to protect against frost penetration. Because of the
relatively small volume of water in a service line, the pipes will
freeze more rapidly than the main distribution line.
Generally where an outside meter setting is used, the meter box pit
should be excavated below the frost line. Even though the meter itself
is not installed below the frost line, the heat rising from the warmer earth
excavation below the frost line will reduce the possibility of freezing.
With proper precautionary measures, the number of frozen services
and meters can be held to a minimum.
For those locations in which a remote possibility of freezing exists,
Badger's thermoplastic or bronze Recordall meters with cast iron
bottoms are recommended.
