(A) Customers having boilers, hot water heating systems or hot water heaters (heating systems) connected directly or indirectly with the distribution mains of the town must have a backflow-type preventer in the supply pipe to any heating system and a relief valve at some point between the backflow-type preventer and heating system.
(B) All customers are hereby cautioned against danger of collapse of boilers, since it is sometimes necessary to shut off the supply of water without notice and, for this reason, a vacuum valve should be installed in the steam line to prevent collapse in case the water supply is interrupted.
(C) The town will not be responsible for accidents or damages resulting from the imperfect action or failure of check, relief or vacuum valve.
(D) Backflow-type preventers, relief valves, flush valves and vacuum breakers required or recommended by this rule must be installed and maintained by, and at the cost and expense of the customer.
