We are trying to fix a problem with a float switch that controls an automatic fill valve in a small (15' X 15") decoraive fountain.

The float switch is installed in the fountain inside of a still tube to prevent unnecessary switching.

The float switch controls two time delay relays and switches about 20mA at 24VAC.

The switch is a reed switch and is designed to handle .5 Amps at 120 Volts.

The problem is the switch starts sticking after a few days or within a week. We don't believe that it is a mechanical problem.

Everyone we talk to agrees that the switch and the design should work but yet we are still having problems.

HELP!

Does anyone have experience with fountain or similar controls? Has anyone came across this problem before?

Thanks
Brian
