in THE MAIN WALL

This weeks case is about a heating system I thought I knew well. We replaced a circulator and had to drain the system. The video will talk about what I discovered and other ways we found to dislodge stubborn air pockets. Seeya Friday @6am EST

    After you make that expensive repair and you still have the same problem, What will you check next?

    If you are highly regarded as an expert and friend of the customer, then you should recommend to the person in charge that they have the isolation valves around the pump rebuilt to save them time and money on future repairs. There are great local companies that can do this work.

    The increased pressure also increases how much air will dissolve in the water.

    On bigger buildings it pays to evacuate air before filling. I used to ask big bucks$$ for this service and got few customers. Instead hours were spent bleed here, there, and everywhere.
