After my little contretemp I researched many automatic devices. I wanted the benefits of a shore supply, but I also wanted it to be fail-safe, or in my case idiot proof.
If you look back at my “urgent help” post you can read all sorts of suggestions.
I finished up buying
a 12 volt solenoid water shut-off valve which is always open. When current
is applied it closes the water off in about two seconds. Current
comes from the extra float switch in the bilge
. A latching relay is needed to keep the current flowing even when the bilge pump
lowers the water and deactivates the upper float.
Picture of shut-off valve on the regulator, attached.
Once this system is installed you can do all sorts of things with the relay, like ringing a bell or shutting off an AC pump or any other motor
you want to close down in the event of a flooding.
Just for good measure I also fitted a tap on the end of the hose where it screwed into the regulator, in case anyone switched the faucet on at the dock.
It has been an experience I don’t want to repeat, or wish on anybody else. But it’s not in my nature to just say, “Can’t use dock water any more because it’s risky.” You might as well say, “Don’t use shore power
,” where I have seen some very dodgy connections, or anything else use on a modern boat.
