HydroCheck Hi-Lo Pump Switches are "electronic float" switches that are designed to work in sump pits. They are particularly useful when the sump pit is very large and may take more than 90 seconds to empty, or the water table is unusually high and it isn't practical to try and empty the pit every cycle. The real advantage of the Hi-Lo Pump Switch is that it lets you accurately set where the pump turns on, and where it turns off. And, unlike traditional float switches, the Hi-Lo Pump Switch has no moving parts that can seize up or get wedged between the pump and the wall of the pit and prevent the pump from running, or cause it to run continuously and burn out. This makes the Hi-Lo HC7000 Pump Switch many times more reliable than float switches and, because it's electronic, it has features that just aren't available in mechanical switches, such as the alarms that are described below.

With the HC7000 there is no babysitting - it will automatically turn the pump on when there's water, and turn it off when the water is gone. It has a built-in anti-airlock feature that will make 5 attempts to clear an airlock by shutting the pump off briefly if the sensor is still detecting water after the pump has run for 90 seconds. Whether replacing a switch that has already failed or just being pro-active and avoiding the damage that will be done when the switch finally does fail, installing a Hydrocheck Model HC7000 Hi-Lo Pump Switch just makes sense to prevent basement water damage. And it works with all brands of pumps, like Flotec, Simer, Wayne, Rigid, etc. 1/2HP or 14 amps max. 2.5 amp min.

The control module is plugged into a 120 VAC outlet and the pump gets plugged directly into the control module. The sensor is then strapped to the side of the pump at the level where you want the pump to turn on, keeping in mind that most utility pumps need a minimum depth of water (normally 1/2" to 2") before they should be turned on. The sensor will work at any level you set it at.

The sensor is shaped roughly like a pen, and senses water by measuring the resistance between the tip of the probe and ground. When the water is touching the sensor, the resistance is relatively low (Figure 1). when the water drops below the sensor tip, the resistance is very high. Once the sensor triggers the pump to turn on on, the control module will run the pump until it loses suction. It knows when this happens by monitoring the motor current and looking for the current level to drop when the pump transitions from pumping water to pumping air. To be able to do this reliably every time it turns on, the Utility Pump Switch needs a minimum runtime of 5 seconds. In other words, once the pump turns on, there should be enough water there so that it will take at least five seconds to pump it all out. 

The Model HC7000 Electronic Utility Pump Switch has a number of built in alarms that warn of problems with the pump or discharge plumbing. The available alarms are described in the table below. Note that the alarms can be disabled by following the steps below:

  1. Unplug pump from control module.
  2. Lift sensor out of water.
  3. Unplug control module from 120 VAC outlet. Wait 10 seconds.
  4. Plug control module back into outlet. Wait 10 seconds.
  5. Unplug control module from 120 VAC outlet. Wait 10 seconds.
  6. Plug control module back into outlet. Wait 10 seconds.
  7. Plug pump back into control module
  8. Place sensor back into water

What the Control Module Does Once the sensor triggers the pump to turn on on, the control module will run the pump until it loses suction. It knows when this happens by monitoring the motor current and looking for the current level to drop when the pump transitions from pumping water to pumping air.
