I recently had my auto top off malfunction and dump 5 gallons of our RODI water into my sump. Not an emergency under normal circumstances, but I had a tank sitter who noticed the ATO pump running and the 5 gallon container empty and replaced it with a full one. At least he noticed the sump level was very high and called me. I shut down the RODI pump and no flooding occurred.
No harm to the occupants of the display tank and I’m allowing evaporation to return the sump level to normal.
I would like input on a sensor for my sump to detect high water level and shut off the pump and send me an alarm/alert.
I happen to have a breakout box on hand.
