GROCO Bronze Vented Loop, 1-1/2 Inch Hose Anti-Siphon Valve
GROCO Bronze Vented Loop, 1-1/2 Inch Hose Anti-Siphon Valve
The GROCO HVL-1500 is a bronze vented loop built for 1-1/2 inch hose, designed to prevent backflow and siphoning in marine plumbing systems such as head discharge, cockpit drains, and other below-waterline hose runs. By introducing an air break at the highest point of the hose run, a vented loop like the HVL-1500 stops water from being siphoned back into the boat when the vessel heels or when water levels shift, which is a common cause of unwanted flooding through thru-hull plumbing.
Constructed from plastic with a bronze finish, the HVL-1500 is sized for 1-1/2 inch hose and is supplied as a single unit. It carries a nominal wall thickness of 0.125 inches and measures 8 inches by 7 inches. This fitting is intended to be installed in-line on hose runs where anti-siphon protection is required, and is compatible with standard 1-1/2 inch marine hose.
