Hello Chris and Alex,

In episode 75, you were discussing leak detectors. In a previous job we used leak detector tape to detect flooding of the water fittings in semiconductor LPCVD furnace. They were about a 10 foot of cloth tape with two wires running on the outside edge. Any liquid (or heavy feet) on the tape would cause the electrical circuit between the two wires to short and trigger the water leak error in the PLC and power down the equipment. The tapes were a few meters long and we would make the tape snake across the floor in 3-inch strips. I like these much more than the flood sensors since you can draw a box around a leak prone device like a water heater or sink rather than waiting for the compartment holding the faulty devices fills up enough to trigger a flood sensor. While in my professional life, they were a bane as any drop of water or isopropyl alcohol misplaced on the tape powered off the furnace,  I wish I had the few extra bucks to add a few of these to my Home Assistant to watch for failed sump pumps and rusted out water heaters.
