How The Tank Level Controller Works

How the Tank Level Controller Works

The position of the sensors determine when the control module turns the pump on, and when it turns it off.
The sequence below outlines the operation of this switch as follows:

When both sensors are detecting water, the pump is off
When the water drops between the two sensors the pump stays off
When neither sensor is detecting water, the pump is turned on
The pump stays on while the water is between the sensors
The pump is turned off when the water reaches the top sensor

Things To Keep In Mind

The "piggyback plug" attached to the mechanical float switch cannot be used with the tank level controller. It must be disconnected and remain disconnected.
If your sump pump has an internal float switch wiring, i.e. doesn't have a "piggyback plug," then you must secure the float up as if the pit were full so that its internal switch is always closed and the pump enabled.
The sensors shouldn't touch anything else in the pit, like the wall, each other, the discharge pipe, pump, etc. If they do, the tank level controller might be confused and think it is time to turn the pump on, or fail to turn it off.
The tank level controller works with any 120VAC pump up to 3/4HP and a maximum of 14 amps.

Frequently Asked Questions

Q. "How far apart can the Tank Level Controller 'sensors' be placed vertically apart from each other?"
A. The location of the sensors is only limited by the length cables (12ft), but other than that, the sensors have no other restrictions as to how close or how far apart they are placed vertically or horizontally. When water is above both the sensors then the pump will be off. When water is below both sensors the pump will be on.

Q. "Do you offer a pump switch that operates opposite of this tank level controller?"
A. We offer the Hi-Lo SumpController which works opposite of the Tank Level Controller. The purpose of the SumpController is to make sure your tank does not overfill. This item is designed to be off when both sensors are not contacting water, and as soon as both sensors do contact water, the pump turns on and drains the pit until the water level drops below the bottom sensor.

Q. "How do you secure the Tank Level Controller 'sensors' so they will not touch anything else in the pit?"
A. One suggestion: Straighten a piece of small diameter copper tubing (3/16" or 1/4") approximately 4"-8" long. Form the copper tubing to make a tight diameter half circle at one end which will be the top. Form a loop at the other end or bottom. Now make a 90 degree bend in the middle. The straight portion of the tubing with the half circle at the top can be attached to the discharge pipe using zip ties. The half circle will keep the tubing from slipping down through the zip ties. The sensor can then be attached to the loop sticking out and away from the discharge pipe. Make one for each sensor.
