Ok, so I bought a cheap one off Amazon, as you suggested. I checked the RO water. It reports 19ppm on average. I tested it a number of times. Ran the RO water for a bit, captured a few ounces in a glass, stirred the water around with the end of the tester, and it averaged as low as 17 and as high as 21. Most often it was 19, spot on. The LCD indicator screen stayed green.
By contrast, the tap water, which is artificially softened with salt pellets, returned more than 500ppm. The LCD indicator turned red.
What does this mean? Google is telling me these numbers are not unexpected.
And I still don't know why the Ro water makes my cat throw up.
Nevada water runs about 375PPM. Softened water is nothing more than salt added to the water to remove calcium but load up with a ton of salt, hence 500PPM. That is our reading on softened water as well. Softened water should never be consumed. Even if you run it using a Brita or Pur, it removes maybe 10-50 PPM, doesn't do anything to remove the bad salt from the water. The purpose of softened water is really to not leave calcium in the sink and shower.
My whole house RO has about 1 to 3 PPM here in my new home. The one that the Costco vendor put into my prior home ran about 5 to 15 PPM. The RO has a couple of "membranes", which what is called, one should be replaced yearly and the others every 3 years. Get a water quality company to come in and service your RO system once a year or you can do the change yourself, by buying the "membrane", which looks like a tubular filter. Technically, RO is about almost as pure as distilled water. Maybe Kai prefers water with a bit more minerals as in bottled water.
