Water softener was installed about 4 years ago. No problems until a week ago. Owner said salt level ran out completely and owner added Morton's pellets (as recommended by a sticker on the lid of the softener). Owner had previously used Morton's crystals on occasion. Shortly after replentishing the salt level, owner began having significant salt and black/brown debris in water lines. The salt and debris has significantly clogged any screens on faucets, washers, etc. I have bypassed the water softener temporarily, but the problem seems to continue. Even though the softener has been bypassed for a week, salt/debris continues to clog the faucet filters, etc. I am suspicious that debris and salt crystals are in the hot water tank as well. Any suggestions? Anyone run in to this in the past? I am at a loss as to what to do next.
