Well, I've never really had access to a TDS
meter until recently....I always just changed all my filters about every 4 months to be safe.
My tap water reads 360ppm.....ouch.
I just changed all my RO
filters and my DI
filter too, and the TDS
is 15ppm. Is this really that bad?
I was thinking I could add another DI
stage at the end....I've read others doing this with success.
Any other thoughts?
If it fluctuates between 15 and 20 ppm
, is this really a problem?
