Visually
inspect the valve(s) on your boat. If the valve has a stainless
steel stem (silver color), the valve should be replaced during
the next scheduled haul-out.. Valves with a brass stem (yellow
color) require no further action.
FAX GROCO
(410) 712-0160 Department 224 with your request for replacement
valves.
