D.C. Mun. Regs. tit. 21, r. 21-306
All meters and meter bypasses shall be sealed by the Authority or its authorized agents or contractors. Seals shall be removed from meter bypasses only by the Authority and licensed, registered or otherwise properly credentialed contractors who are expressly authorized by the General Manager to remove such seals.
Seals shall be removed from meters and meter bypasses only by the Authority. Removal of a seal shall be presumed to be evidence of tampering and the General Manager may, upon discovery of such removal impose the maximum penalty authorized by law.
Water charges to the customer, owner, consumer or occupant for any period during which the seals are removed shall be based on the average amount of water consumed daily by the customer, owner, consumer or occupant between the date the new or repaired meter was installed and the date a follow-up reading was taken.
