This question is for my son who just purchased his first home with a well. We know very little about wells so it's a learn as we go process. This will be a diy project but we are questioning the order for the instal . The company where he bought the equipment said to install the softener first, followed by the filter and then uv light last, and then the hot water tank. Our question is, would it make more sense to install the filter before the softener so the water is filtered before being softened? Any help is appreciated.
