F J Hess sold us a 2,000$ water system that didn?t do the job. We still had water that was undrinkable. Plus, it was leaving stains in the toilets and tubs. After confronting this company with the problem and a dozen trips to the house, in a nutshell they said the water was untreatable.
With that we called another company (Endless Mountain) to test the water to see what could be done. Endless Mountain built us a custom water system and installed it for less then what F J Hess charged for their generic system. Now we have fantastic drinkable water with no problems. Thanks for the waste of money F J Hess.
