Q. "Will my softener remove tannin?"
A. Since tannin is not a problem for most people, we do not offer a resin that is specifically designed to remove it. Our Soft-Economizer softener comes with quality cation resins which are specifically designed to remove hardness (will not remove tannin).
Q. "How long will the resin last?"
A. As long as strong oxidizers do not come into contact with the resin, the resin will last under normal operating conditions for approximately 10 years, possibly longer. For instance, high iron contact with the resin will cause the resin to 'foul' sooner. There are resin cleaners available for that purpose; however, we do not offer them because most are considered a hazardous shipping material.
Q. "How can I tell if I currently have anion or cation resin in my water softener that I bought elsewhere?"
A. Place the resin in a beaker of brine (NaCl) and then give that solution a good swirl. If the resin floats it is probably anion resin, and if it sinks it is probably cation resin.
