A friend recommended me to you site. I have high levels of iron and manganese (I emailed you my test report), no sulfur, but also really hard water. I had a greensand system that worked fine before but it got destroyed in a fire. I am limited on space in my garage where I want to put the filters. What do you suggest? I want to make sure this doesn’t kill my water pressure.
Thanks for emailing.
Greensand is a proven media to remove iron and manganese and the one we use lasts a long time and easy to service. These filters come with automatic backwashing control valves that are able to meter your water usage to save costs on potassium permanganate.
Following that, we like the 5900 softening system, which uses the same type of control valve as the greensand filter. The 5900e is a a modern, NSF-certified valve that is user-friendly and easy to set up and maintain.
It would be best to install a softener in-line to take out the calcium hardness and prevent spotting and white scale and residue. Use 1” piping to limit any pressure loss through the filters. The high flow bypass valves we use and properly sized tanks make sure you don’t see a large pressure drop across the system.
The result of using this combination of filter systems would be clean, soft, non-staining water. I am including more information on the recommend equipment below:
