TDS Meter is Whacked?-Filters, etc..-3reef Forums

Bigjoeybx · 04-12-2008, 06:26 PM

So I just went and bought a new TDS meter today tested my RO/DI and to my surprise came in around 157. Tested my tap water, came in at 56-60. What is going on? I was expecting maybe 20 -30 from the ro. But why is the tap registering lower than the ro water. I just recently purchased the unit 3 months ago but haven't used no more than 200 gals of pure water. I have the ocean wave 75/gpd

Ok so I manaully flushed the system. Just emptied out all the containers. Damn TDS read 0. Thats whats sup. But my only dillemma now is I have the flush system for it. But for the love of God I don't understand a word these instructions are saying. I really don't want to break my $150 investment. Any help would be appreciated.

ok tds will always read high in the first gal or so of water produced by your ro filter mine dose this consistantly also did you give the tds time to temp adjust to the water in both tap and ro this can produce skewed results

i usually just hold it in the water for about 5 seconds. My tap and my ro should be the same right? Being that I'm checking at the same time. And unit is not new also brought it in feb never flushed it gues thats why I had the high reading at first. Then when I flushed it went completely to 0.

no tap should be high and ro under ten unless you have the di filter then it should be 0

I personaly use a shot glass for my tds testing let it run for about 20 min then fill the shot glass after a good scrubbing and turn the tds meter on and let it sit till the numbers quit changing

to be honest I have a tds that buy.com was offering for $10 with a $10 off cupon if it was your first time purchase with google payment so got it for free but they sell the same one in the rv section of walmart for $11

My di is starting to turn brownish so am about to order more. Any help on this flush kit?

Bigjoeybx · 04-16-2008, 08:56 PM

is that when you know the resin is going bad when it changes color?

describe the kit your have or post a link to it and we can help ya there are many diff ones out there

basicly you reverse the waste water line with the good water line on the ro filter and dump both for about ten gal but you dont want this runing through your di resin
