Question 5: Is an air vent valve required in the piping when an expansion tank is used?
Answer: Yes, air vents must be installed in various locations in the piping system to purge air and are
required at the highest point in the piping system. One of the most common problems in water/glycol
systems is the presence of air in the condenser loop. In addition, an expansion tank is recommended
on glycol systems. See section 2.19 Water/Glycol Cooled Unit Piping for more information.
