Taco 007 Circulator
As luck would have It After I replaced the Aquastat, I found that the pump was bad too. So Now I will show you how to replace a Taco 007 circulator Pump. Again make sure the power is off. You can't trust the switch at the boiler and breakers and fuses are almost always marked wrong. test the wire it's self to be sure the power is really off.
