Our state certified lab had done some health and safety testing for a customer so they can purchase a new home with well water. Everything looked good after testing, but once they moved in they could smell a rotten egg odor in the water. We sent one of our project coordinators out to test the water further and found sulfur in the water. There was a existing filter system, but it could not handle the water conditions. After checking things out we found there is no drain for a EVS sulfur filter. After consulting with the homeowner we decided the best solution was to remove the current filter and replace it with something bigger that can handle the odor. We installed a Big Blue with a MAZ filter to remove the iron in the water and then followed that up with a ONE filter with carbon to remove the sulfur. Now that the new system is installed the homeowners can enjoy the odor free water!
