 Re: EcoWater WATER REFINING SYSTEM (ERR 3500R20)
I have a question about the HARDNESS setting on this filter. When the person came to my house to test the water he said my hardness was 8 gpg (grains per gallon I believe). The filter unit does not go by gpg. It only has a setting for grains (g). It's currently set at 23g.
Does anyone know what the HARDNESS setting should be based on this information?
Thank you in advance! |
