Review on 🚨 120 dB Red Strobe Siren Water Level Sensor Detector Alarm, Adjustable Volume, Sump Bobber Leak Sensor,16.4ft Probe Cord. Suitable for Water Tanks, Aquariums, Swimming Pools, Basements by Drew Beckett

I really like this unit. He keeps an eye on the water tank of my Rancilio Silvia espresso machine so that it doesn't run dry and the boiler doesn't burn out. It's just well built and I think a very good price. I made a plexiglass stand for the low water sensor to stand in the tank. There is a hole for wires at the top of the stand. (There is also a high water level sensor). When the water level is low, the indicator will flash and the buzzer will turn off from very loud to faint. where you put the handle.
