I just purchased a house with a Culligan Mark 812 Water Conditioner. The conditoner was put in about 13 years ago. It doesn't seem to be doing much to condition the water as soap doesn't lather good and there is a strong iron smell to the water. Also, spots on the glasses, etc.
I have it doing a recharge about 2x per week and there is only 2 of us in the house. I had recently sanitized the brine tank and the salt level is adequate. Any suggestions on troubleshooting this? Could it be the media has reached the end of its useful conditioning life and if so, is that replaceable? I hate to have to replace the system as it is not in the budget right now.
