I have a copper counterflow chiller that was dropped and it bent the 1/2” 90 as well as the 3/4 to 1/2 to 1/2 copper fitting. It appears the inner copper copper coil is soft copper which is smaller than 1/2“ in diameter. It appears it was brazed rather than soldered.Any ideas on who to go to to try to repair this. Looks like I need to re-bend a copper 90 as well as remove and replace the 3 way copper fitting. Any thoughts on best way to go about having repaired ? Thanks
