water heater water sensor

[Ryan Wright]

Jay,

Is it a float switch, or a contact water sensor, or what?

If a float switch, these are easy to find. Check Grainger or
McMaster-Carr, they have lots of 'em to choose from. If it's a water
presence sensor as opposed to a level sensor, do a Google search for
"liquid sensor" - there were several interesting results. ("water
sensor" is not a great search term - you'll get a lot of consumer
grade junk. The term "liquid" will turn up more industrial sites where
you have a better chance of getting something that can actuate a relay
and will probably last longer, too.)
