Where a meter has been placed on a pipe connection to a boiler or other hot water apparatus, a check valve must be placed and maintained between such meter and the boiler or hot water apparatus, when so ordered by the Superintendent, which shall protect such meter from back pressure of steam or hot water. In case the meter shall be damaged by hot water or steam, the owner or occupant of the premises shall pay for such damage.
