Customer reply replied 2 years ago
I CANNOT TELL IF WATER IS FLOWING, the pump is making a humming sound, could be plugged
Customer reply replied 2 years ago
can calcium deposits form in the line and plug up the pump ?
it sounded like cavitation for a few seconds then the humming

I replaced the motor/pump unit 12 months ago with a new one. its a taco 007-F5
HVAC Technician: Eddie, Home Improvement Contractor replied 2 years ago

what I was alluding to is if you hear the water flowing through then there is air in the system and needs to be bled ...............have you done that ?.....if you don't hear anything then it should be working...........the other thing is sometimes it is hard to tell if the baseboards are working sufficiently by touch .............so as a test turn the thermostats all the way up and then see if you notice a difference

thanks
