Tds at 12 after sediment and carbon replacement

[Retzius]

Hello,

I just recently replaced my sediment and carbon block filters and I am showing a TDS reading of 12.

Pre RO 408
Post RO 12

My product to concentrate is 4:1


Before changing I was getting a reading of

Pre RO 350~410
Post RO 4~6



Should I run it for a while? I havent really let it for more than a gallon.

Let me know if it will fall or what I should do. Thanks.

You are correct on the calculation but my membrane is the hand-tested version and it is guaranteed to be greater than 98.0%.

Also, its only about 6 months old.

You can wrap the membrane up in Saran Wrap and send it back to us.

We will test it under standard conditions and with a very accurate TDS meter. If the membrane doesn't pass 98%, we will pro-rate you a new one.

Thanks alot Scott,

Right now I am running a varied 97% rejection rate. I am going to see if it goes up higher. If not, I will send it to you.

Thanks. You service and support is awesome.
