Tds 10

[cwklinge]

Hello,

I just replaced my filters with your standard filter pack. However, I've noticed that my TDS went for 4/5 to 10. I've got your inline tds meter and both the input and output reads 10. Is it time for new DI resin and RO membrane? The membrane is about 2 years old and the di is 1 year old.

Your DI resin is exhausted with an RO tds reading of 10 you would get about 500 gallons of water before exhaustion. I don't think your membrane is gone what is the TDS of your tap water and how many GPD is your membrane?
