**Check This** and What's Your source TDS?

I’m in the Midwest and have ranges from 200-400.

I heard some of you said your TDS is 900!?

What’s your TDS and where are you?

Hardest water I ever hooked up to, was over 900 TDS, came out 2 TDS after RO and DI.

I generally run 250-400 TDS here. Depends on the location.

24-128

UK. 380 in. 15 after RO. Zero after Unger Hydropower DI

Here’s a tip. To use less DI resin, always run RO only for a couple of minutes before connecting DI. My TDS after RO drops from 250 to 15 over that period.

130-ish religiously

I saw 600 once… scared me like “Freddy vs Jason” if they both turned their focus to ME.

For several years we were ready steady on 130 as well. Then, they did some major city water supply overhauling and we’re up to 140-150. Crazy

At 130 what does your RO membrane get it down to?

On the outer rim of our service area it gets down to 050 ± which helps me to see the trip as being worth the extra time travel time. RO only on those days days!

well mine was 1520 ^^^

TDS is really not a true measure of Total Dissolved Solids. Silica is one of the most common minerals in the Earths crust. You will need a meter for testing the silica too. I have a link on the blog with a bright yellow picture of a silica tester. Here is the link if you don’t want to go to my blog.

But there is a lot of other really cool stuff on the blog now that was never there before. Come on over for a visit.

Finally got my hands on a TDS meter and checked my unfiltered well water here in Central Virginia

My area has an average of 77 TDS according to the database, but water from my well tested at only 18. (some jugs tested 17)

I haven’t tested the rain water here yet, but it seems my well will be a nice backup for my WFP, without taking a beating on resin.

EDIT
I had a couple light showers today, so I tested some rain water. However, I don’t think it was a hard enough rain to get the roof wash off. I have not set up a proper catchment system yet, so a harder rain with a roof wash filter will get much better results. Anyway, the rain water tested 15, but I know it had some pollen in it.

I also tested some store bought drinking water…
“Natural Spring Water” bottled from a spring in PA tested 120.
“Purified” with the label stating “purified by reverse osmosis” tested 23 !!!

I was surprised that the commercially bottled “spring water” was over 100, and shocked that the “purified” store bought water tested higher than my unfiltered well water.

Edit
Had a harder rain today, so I tested again, and I got a 6 from unfiltered rain water from a galvanized roof under a tree, Anyway, I think I could easily get this way lower with the catchment system I will be building soon, but 6 is good enough really.
