Question about 3 stage problem?

My friend picked up an Ionic 3 stage caddy form another supplier, he is new to pure water and I have very little experience with them, his tap water is running around 50 tds, when it runs into the carbon and RO it is coming out with a higher tds around 60 or so and then is cutting down on the life of the DI. This other supplier said they think he needs a pump. I do not know his psi in the area, but he is running his pole at 2 stories and under. Thanks for any help!

Bumping the buried, any suggestions folks!

I’m happy to help him personally.

I know that system very well.

Have him or you call me tomorrow.


Thanks Shawn

I will pass on your number to him.
