17.35.104    PIPES, FITTINGS, AND HOSES

(1) All tanks, pumps, lines, hoses, and other equipment should be clearly marked as "nonpotable" with a permanent label placed in a conspicuous location.

(2) All discharge piping should be made of flexible, heavy-duty material that will be non-collapsing and non-kinking with locking interconnectors. Corrugated or ribbed hoses should not be used.

(3) Lines should be watertight and appropriately fastened or secured to the dock or pier. Forced main systems should contain appropriate "thrust" blocks and other security fastenings.

(4) All lines and hoses should have an approved backflow prevention device that meets the requirements of ARM Title 17, chapter 38, subchapter 3.

(5) A valve should be provided on the discharge line at the pump and on the suction hose at the nozzle. If a suction hose is to be installed in such a manner that sewage would discharge from the line when the pump is removed for service, a gate valve should be provided on the pump end of the suction hose.

(6) Positive locking connections on the end of the discharge line should be provided to prevent it from coming loose during discharge. A friction nozzle (right angle preferred) or wand-type attachment should be provided on the end of the suction hose. Adapters should be provided to fit any discharge connection from one and one-half to four inches in diameter.

(7) Discharge lines should be protected from freezing and prevented from leaking into the water.

(8) Suction hoses should be equipped with clear tubing or a sight glass on the suction end of the hose to allow the attendant to determine when pumping is complete.

(9) The connection between a suction hose and a vessel should include pipe splash guards or positive locking connections to prevent spilling from the suction hose or disconnection during waste discharge.
