Details for BUILDING WATERS - Ad from 2020-11-22

Ask the expert: **Attention all readers!!!! If you have a plumbing or heating question, please call our office! We may use your question in the paper! ** Q Every year I have to bleed my radiators. Is this normal? Does everyone have to do this? - Steve - A Old systems have a non-bladder style expansion tank. Most of these pumps were installed on the return line to the boiler so that the pump could draw the air from the tank. Also, when the system cools down in the spring, the pressure can drop in the system allowing new water to enter, which will introduce air . Newer systems are installed differently with air separators and bladder style expansion tanks that will help to minimize air in the system. You are definitely not the only one having to do this Steve, and it is good that you do. Thanks for the question. - - Dan Miller, VP / HVAC Division Manager 262-989-1001 wisconsinmechanicalservice.com
