Our first snowbird winter we stayed for a while in Terlingua outside Big Bend. I have no idea what the level of dissolved solids in the water was. It was cloudy, smelled horrible and tasted worse. I swear you could chew it. It turned our fixtures white in three weeks. Bottled water was about the same price as gas.
The next year we were in Gold Canyon, AZ. Being used to our pure Colorado well water, the AZ water was too hard for coffee, ice and drinking. We saw lots of snowbirds using the Flow-Pur. We ordered one and had it delivered to the park. It was like night and day.
We have used it extensively in Utah and Arizona for several years and highly recommend Flow-Pur.
