Whenever water meters inside the City are found by the Bureau to be without adequate support, or with defective plumbing, or without shut-off equipment necessary to permit meter tests by the Bureau, or where through earth movements or subsidence, pipe bends, or connections have become faulty or are not tight, then the Bureau shall notify the owner to remedy the condition within 10 days from the date of notification. Where the notice has been given specifying the repairs or alterations to be done, then if the repairs or alterations are not completed within the time allowed, the water service shall be shut off until the repairs or alterations are completed. The Administrator may allow additional time for completion of repairs or alterations for extenuating circumstances.
