Hi Folks,

I just replaced a circulation pump over the water heaters. I am now having a problem where 10 out of the twelve hot water taps have hot water coming out of them, but two have cold water coming out of them. I turned all twelve of them on at the same time (relatively same time) trying to purge any air that may have entered the system when I changed the pump. As far as I can tell, the Taco pump is the only one in the house. The two faucets that push only cold water are located in different parts of the house. One was at the kitchen sink and the other was in the master bath upstairs....

What would cause this anomaly?

Thanks much.

Fergie
