Mr Byerly sells 1980 water technology. Mr Byerly charges premium prices to do yearly maintenance but does not rebed filters or do valve maintenance which results in poor water quality. We just paid $250 for our yearly maintenance & our water stinks, taste bad & Is brown. It ruins our laundry & when tested by another water filter service it showed an extreme high iron content, which Byerlys filter system was supposed to have fixed. That plus the fact that he will not return our phone calls leads us to remove this system & find a more reputable company.
