If your meter needs to be removed for service or cleaning the plug can be installed and the flow restored until the meter is reinstalled. The operator simply turns off the water flow, removes the stainless steel pin, pulls out the meter, installs the plug, reinserts the pin, and restores the flow. The standard plug fits any of the saddles sizes and can be used with both the Pipe Mounted Meters and the Detached Display Meters. Plugs can be purchased as an option when ordering meters or purchased separately.
