Tap water TDS at 4???? Holy cow! I find that pretty hard to believe unless your utility uses membranes for treatment. A tap TDS of 4 would be highly problematic as it would be extremely agressive to plumbing fixtures, piping and appliances. It would suck the lead and copper out or brass and bronze, eat stainless steel and have a really wacky pH and Langlier Index. No utility in the USA could provide water to the public like that as it would not meet the EPAs lead and copper rules.
I am not doubting you or suggesting you are fudging but as a water treatment professional I cannot fathom that.

Yeah, in the Greater Vancouver region it can range from 4 to 12ppm, depending on where you are and what time of the year it is. When I tested mine a couple years ago it was 4.

Right now my tap water has a pH of 6.3 and no detectable hardness. (I don't have a TDS meter anymore.) We live in temperate rain forest (or at least surrounded by it) where it rains a lot so our water is very pure.

I wasn't using an RO/DI with my salt water because I thought there was no need to. Then I found out our tap water had high amounts of copper and who-knows-else what kinds of other metals, which the water obviously picked up from the pipes. Not so high that it threatens a persons health, but for marine inverts it can, and did. So that sucks.

What also sucks is I have a African cichlid tank and I need to add baking soda and sodium or calcium carbonate just to keep the pH and water hardness up.

Great for South American and other soft-water tanks, though.

Thanks all for your readings, I re checked mine and let it run for quite a while as I did before. It showed 325 on Fri, Sat, and Sun. I guess it was a spike form who knows where.

From what you guys wrote, I seem to be on the high side of the norm but still ok, apparently I will just use filters faster....great. I seems that Atlanta ,BC and Boomerville are well below the natl' average and the place to be for low tds water. Phoenix and San Diego looked to be the highest TDs levels. Florida seems to be the most similar state, swamps, on the gulf etc. The water was much better though, probable due to having a Government/Governor.

Any others on the gulf coast with readings? TX, MS, Al?

~460 near Indianapolis.

... we're rated one of the worst in the country.

Wow, Atlanta!

Aren't cities required to add fluorine to our water, and to treat with chlorine or chloramine? Curious what good RO water with just the required additives (if there are any) would bump the TDS up to.

Over hear in the Decatur, GA (sub of Atlanta), mine ranges from about 44-48, depending. That also agrees with the county water analysis they post. They do use chloramines, I believe. I have not checked it in about a month or more, so the drought may have impacted it.
