I've just removed the unit from the old tank and cleaned it - the float moves up and down fine and the resistor wire is in tact - if not a little loose, but I'm not sure the easiest way to test them to see if a current will still get through the old solder joints ? Don't really want to wait until the whole thing is back in place to find is doesn't work!! Any advise welcome.
P.S - Anyone know if you can get replacements - The unit is the type with the float inside an aluminium tube.
