So I live out in the country "Rosharon". We're on a water well and my tds is around 750 before going into my Ro/di. I'm blowing through filters from brs trying to keep my tds as low as possible. Does anyone have any ideas or experience with this? My idea was to start bringing in water from the local water mill express and running it through a DI setup and call it good. I've checked the watermill express and the tds i got was like a 5 or 6 if i remember. Their water is just Ro according to their website. I'm at my wits end with the water situation and its almost got me to the point of getting out.
