Customer called in about Halo 5 and still having weird smell from the water. Evaluated Halo system and determined it was missing shut off and boiler drain as part of the install. Went ahead and installed one and treated the Halo 5 as a new install. Also noticed that nylon was ran as a discharge line and was hanging over other water lines. Went ahead and removed nylon discharge and installed ridged drain line for new discharge. Performed backwash cycle few times with draining in between each cycle. Halo no longer leaks and if smells issues persist, will need to contact Halo manufacture and get unit replaced under warranty.
