What to Do When a Circulator Pump Stops Running
A defective circulator pump can make your life uncomfortable especially during the winter. When your circulator pump stops running, it may take a bit of time before your get warm water on the taps. This situation can be very irritating especially in the morning when you are in a hurry to go to work. Since it is impractically to run to an expert for help every time your circulator pump dies, you should learn how to troubleshoot your pump and get it running. To help get your circulator pump running, here is what you should do.
Check the Power to Your Circulator Pump
One of the most common causes of circulator pump problems is power failure. If your pump no longer has power, it will definitely stop working. To check the power of your circulator pump, check the voltage. When checking the power supply to your circulator pump, your first stop should be the circuit breakers and the power outlets. Make sure that the circuit breakers are on and that your pump is plug to the power source. If the circuit breakers are on and your pump is plugged to the power source, check for voltage. To do this, remove the cover from the circulator then use a multimeter reader to see if the motor is getting enough power. In the United States, appliances need to 110 volts to run.
Check the Zone Valves
If your circulator pump is getting enough power but it still does not work, you should check the zone valves. The zone valves are small motorized valves that open and close to direct the flow of heat so if these little valves are not working well, you may not get hot water in certain parts of the house. To make sure that these small valves are working well, test the valves.
Replace the Circulator Pump with a New One
In case your circulator pump is totally damaged, it would be better for you to simply replace the pump with a new one that to attempt to repair it. To install a new circular pump, shut off the power to the circulator pump and turn off the water supply. After shutting down the power and water supply, remove the wires that are connected to the old pump. Recap the ends of the wire with electrical caps. Make sure that the wires do not come in contact with water. Remember that water is a very good electric conductor so be careful not to get the wires wet to avoid accidents. After removing the wires, remove the screws that are holding the old circulator pump in place then left the old pump out. The pipes connected to the old pump will be open once you remove the pump so be ready for water rushing out.
After removing the old pump, put the new pump in its place and make sure that the new pump is securely connected to the pipes then tighten the screws that hold that pump in place. Once the new pump is secure, uncap the wires and reconnect them to the pump.
