Troubleshooting a Circulator Pump | DoItYourself.com

A boiler's circulator pump is used to remove hot water from the boiler and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.
