Hi Byron.............do you hear water flowing through?

Customer: replied 1 year ago.
I CANNOT TELL IF WATER IS FLOWING, the pump is making a humming sound, could be plugged
Customer: replied 1 year 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
Expert:  Eddie replied 1 year 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

it is odd because you hear it running..........and not making a strange noise?.......you are getting heat .........there are no leaks right?........any corrosion deposits even minute that you see?
