Hi All,
Just tested my tap water TDS for both Manjeera( Hyderabad) line and borewell or tanker line.

Both came around 250 PPM.

I am staying in my friend’s flat. He has an RO installed. The RO water came out to be 18 ppm.

Is it really required for people having below 250 ppm to have RO installed or is it just a fear psychosis?

Articles say that 150-250 ppm is safe drinking water.
