Review on 💧 Reliable DiversiTech WS-1 Wet Switch Flood Detector - Get the 2-Pack for Optimal Protection by Frank Garahana

Works great, works well. It took over 24 hours to dry even with silicone desiccants so the air conditioning didn't work until it was restarted and reinstalled. Tip: If you don't have a drain switch, don't install one on the external (secondary) sump of the air handling unit, as by this point water will already have entered the interior of the unit, possibly long before the problem is connected. The mold will already have accumulated by the time a flood is detected. From a design perspective, I think it makes more sense to place this sensor on the bottom of the air conditioner to detect water coming out of the manifold rather than dripping.
