The seacock is a Marine Hardware unit that is UL Listed Marine and all that. Funny thing is, most of my purchases were Groco valves, but they were out of the 1" model and so I bought this Marine Hardware unit. The Groco valves say nothing about needing grounding.
You are right, keelhaulin, and the Marine Hardware unit says the following:
• Housing cast of heavy-duty 85-5-5-5 naval bronze; machined with tapered pipe threads (NPT)
• Chromed bronze ball for maximum saltwater corrosion resistance; SS ball stem
• Grounding screw for connection to the boat's bonding system, (sizes 1/2" to 4")
• Drain plug for easy winterizing (sizes 3/4" to 4")
• Handles are coated with a thick, non-slip plastic for a sure grip
• Bronze body⁄SS hardware - cathodic protection is required; includes grounding screw for connection to the boat's bonding system
I have a call into Marine Hardware to find out their viewpoint. Maybe it is that this unit is not insulated from electrolysis properly and thus the warning, but in that case, why is rated for marine use?
