Frozen Pump System?

Allow pump to completely thaw out from the freeze before calling for service. As long as there are no broken pipes, pump castings, or broken pressure tubing, the pump should start working normally when it has thawed. If any of the above appears to be damaged, turn power off and call Rainbow Pump for service. Or you can try the steps listed below before calling for service. 

First, we recommend checking the control box, (gray box next to the pressure switch) there is a 1/4" nipple that comes out of the bottom of this switch that tends to freeze very easily.

You can try using a hot towel from the dryer to wrap around the pressure switch or use a hair dryer on low.  The points on the pressure switch need to be closed to bring water through the system.  If the points on the switch are closed and no water is delivered, you'll need to shut down the system and find where the system is still frozen up, most likely the pipes coming out of the well head are not well insulated or the insulation has fallen down and is wet. You don't want the pump to run but have no water pumping, this will burn up your pump.

PRECAUTIONS FOR PREVENTING DAMAGE FROM FREEZING WEATHER

1.Cover pump but keep well ventilated

2. Run water at slow trickle in a safe area to keep water moving through the system.

3. Use heat tape
