Strange TDS readings

[m-six hundred]

Their ad off of their web site. 99% rejection extends it three times and its probably more for us Arizonans who have 600 tds.

And to answer your questions No I do not get a year off of a Max Cap Cartridge.

I probably make close to 900 gallons a year.

7 gallons of top off a week = 364 gallons of top off alone.
10 gallons a week water change = 520 gallons a year.

The In meter is usually reading the RO water TDS, and the Out reading is reading the DI. The DI needs to be replaced. Once DI is full exhausted it will read higher than the RO water TDS. Once this occurs you will start contaminating your water. Your membrane may be fine, but you wont know unless you can measure your tap water TDS.

THE DI absolutely needs to be replaced.
