Frequently Asked Questions

Q. "Why would I need one of these switches?"
A. These electronic low water shut-off switches can be used in many applications to protect your pump from running dry. These switches will keep the pump on until water falls below the sensor. Once this happens, the pump is shut-off to keep it from going dry and causing your pump to burn out.

Q. "How hard are these low water shut-off switches to install?"
A. These switches require no tools to install. Simply place the sensor at the position in your tank or pit where you want the pump to turn off, plug the control module into a standard 120 VAC outlet, and then plug the pump into the "piggyback plug" on the control module.

Q. "How can these low water shut-off switches save my pump?"
A. These switches can stop your pump from draining a holding tank or pond. Once the tank or pond is empty, the pump will begin to take in air, thus running at a faster current and eventually burning the pump out. This can happen for many reasons, such as if you have a tiered pond and something happens in the upper levels causing your water to overflow out of the channel and away from the lower pond and the pump. This could eventually lead to your lower pond being completely drained of water. This could potentially harm or kill whatever aquatic life you may have. These switches can be placed inside the lower pond at a desired position, thus shutting off the pump prior to it draining the pond completely.
