§ 52.41  USE OF WATER.
   (A)   When a new service pipe is put into any premises, the service cock shall be left closed and will thereafter be opened only by an authorized employee of the Department and only upon the request of the owner or his agent; provided, however, that a licensed plumber may open and close a service cock to test his work, as provided herein.
   (B)   Where a building originally built as a single dwelling and fitted with one service pipe shall thereafter be subdivided by sale or otherwise, the separate division so made must be connected to the water main by a separate service pipe within 30 days of such subdivision.
   (C)   Where the water has been turned off by the Water Department for any reason, no person or persons except authorized employees or agents of the Department may turn it on again.
