The water may be at any time shut off from any or all mains, without notice, for repairs or other necessary purposes, and the City shall not be liable for any consequent damage. Water for high pressure or other steam boilers shall not be drawn directly from the City mains, but shall in all cases be fed into a suitable tank of sufficient capacity to supply needed water for at least one-half (1/2) day. While water is temporarily shut off from the mains, the hot water faucets of all premises should be kept open, to allow steam to escape from the hot water boilers, and to prevent bursting or collapse of the same. No person shall leave a house empty with the faucets open as above explained. (Ord. 632, 7-28-93)
