Flood and Pump Protection
Consider investing in a flood protection device. There are a multitude of devices that can detect water leaking on the floor and shut down the well system.
Low Yield Wells
If you have a well that occasionally runs out of water or you would like to protect your pump system from burning out due to a leaking toilet, install a PumpTech or QD low water cutoff. This is an electrical component that senses when the well pump is about to run out of water. This device will shut the well pump off. An internal timer will automatically turn the well pump back on after the well has been allowed to fill. This will prolong the life of your well pump. These devices are cheap insurance as opposed to the major costs of a well pump replacement.
