Mr. and Mrs. J. had numerous problems with their 20+ year old water softener. They had to manually regenerate it, and when they did, the brine tank would over fill. Not only that, but they constantly experienced staining from all the iron in the water. They had enough and gave us a call. Due to the higher levels of iron, the EVFE iron filter was a perfect fit so that all iron was removed and so that the new water softener was protected. In addition to the EVFE iron filter, they replaced the old water softener with a new EVRS that is much more advanced than what was previously in place. They now have water treatment that does not need a manual regeneration, doesn't leak and takes care of all of their concerns.
