Lesson Learned/Best Practice

Subcontractor asked for a change order to bring in a freezing vendor rather than drain the system.  When planning a renovation where we’re tying into existing hydronic loops, mandate freezing the lines at tie-in’s instead of depending on there being isolation valves, in order to avoid draining the loop and losing the glycol and treatment chemical.
