Eliminate the use of float switches with CP2-110 for your well water holding tank.

This product is fast and easy to install on your own well water holding tank to replace those electric float switches permanently.  You will now have no moving parts in the water to wear out, virtually eliminating the moving part(s) failure points for these water storage tank systems.

  • Floatless Water Level Control
  • Low Cost Solution for residential well water holding tanks

The sensor head with its five foot long rods have a low water alarm to turn off the booster pump if water gets too low and a fill on/off switch points to turn the well pump on and off at different water levels. The sensor head is designed to go into the top of the tank or mount along side the tank in an external static pipe. The sensor rods will not foul, plate or deteriorate no matter the water quality and comes with a 100% Satisfaction Guarantee.

The Power supply is designed to go into a new or existing electrical panel that has the well pump relay (110VAC coil) and the booster pump relay (110VAC Coil).  This power supply can use 110VAC or a 220VAC, available for the same price, just let us know you want the 220VAC version.  All the connections between the power supply and the sensor are color matched to make the installation easy and fast.

These relays need 110VAC coils so they can be wired into the Waterline Controls™ Power supply (PS2) that is provided with this set-up. We have supplied a wiring diagram where all the colors coming in from the sensor head are connected to matching colors in the power supply, making this part easy to figure out and wire.
