The Bureau may test and/or repair any meter on services supplied directly or indirectly by the Bureau at any time without application from the property owner and for this purpose may upon notice temporarily shut off the water. If a meter which is larger than 1 inch on City lines requires repairs, the Bureau shall give notice to the property owner or user and immediately place said meter in good working order. If the meter is not repairable due to wear, obsolescence or parts that are not available, the Bureau will replace the meter in accord with Section 21.12.270 "Ownership of Meters."
