My clients were concerned about the water coming out of the fridge being milky. I checked for leaks and eventually pulled out the fridge and purged the ice maker line. We tested the water and it seems to be significantly better. My clients were happy and we put the fridge back. Water heaters are 6 years old. Water pressure was at 85 psi. Dynamic testing shows both the expansion tank and PRV are failing. I left several options for replacement and gave some options on whole home filtration that my clients had interest in.
