I have a new mobile home rental property that is on a well system the water has strong egg smell and discoloring of tub and sinks. I was going to install a whole home system from Home Depot or Lowes. We checked for the best place to install but the water heater is be hind a panel that is time consuming to remove and could eventually break the panel with constant removal to change filter. Under the house we could only find one single pipe running up from the ground into the insulation. The instructions for the filter states that the filter system should be installed on a horizontal pipeline but we can’t find one. Do we have to pull the insulation down? Also any recommendations on a particular brand of filter?
You need to identify the cause first.
What color is the staining? Red, brown, tan = iron
White is carbonate i.e. hard water
Black is manganese. Rotten egg is hydrogen sulfide. You really need a local water treatment company to test the water and provide a treatment set up for you. There is no one size fits all in water treatment it depends on the levels of each contaminant and water chemistry
Try a Home Master HMF3SDGFEC 3 Stages, particular designed for treating well water. I read somewhere on homekitchen101 that this system not only rids the unbearable odor, but also reduces iron, which is the main culprit of the discoloring in your faucets.
