I got a TDS meter today - one day before my RODI filter should arrive.

My tap water is reading 258ppm TDS.

How does that compare to anyone else who's measured their tap's TDS?

Nationwide 250 is about normal. In the Southwest it is usually higher. Mine in Phoenix was 736 two days ago. It varies due to the blending of several sources including the Colorado River, Salt River and Verde River but its never under 500 and can exceed 1000 at times.

BTW at 736 TDS tap my RO only was 7.7 on a HM Digital COM-100 conductivity meter and RO/DI was at better than 10 megaohms. Thanks to my new Spectrapure MaxCap RO/DI system. Right at 99% effieiency from RO only, not bad in my book.

Here in Vancouver, Canada:

10 - 20ppm TDS straight out of the tap.

No wonder you Yanks want to buy our water so badly . . . :p

~30ppm out of the tap. My city uses a membrane system at the water plant. And I still run it through my own RO/DI before it goes in the tank.

How does 736 taste?? :p J/K

About like chewing on sand! With the mineral content it actually tastes pretty good if you let it sit out to dissipate the chlorine. The only time it tastes bad is in the spring where there are MIB and Geosmin algae blooms in the lakes and canal systems that deliver the water to the City. Then its awful. MIB algae at levels of about 1 to 2 parts per billion is detectable to the human nose and its really offensive.

About 64 ppm here in Flagstaff, AZ. Most of our City water is pumped from wells on a 13,000' mountain right on the edge of town. Its a bit different than down in the desert.

60-70ppm here in Worcester, MA. I lived in a condo about 7 miles away for a while that had 1,000+ppm. I think the highest I ever checked was about 1,300ppm. The RO/Di still stripped it down to zero though.

so.....is it a bit odd that i have almost 50 ppm of no3 and 3 ppm of po4 in my tap water, but its only 60-70 ppm of tds?

I've found that I'm actually getting over 300 ppm readings (here in Omaha) after the water's been on for awhile. Some of the TDS must settle out of the water when its in the pipes, maybe? Its under 250 when I first start up the water.

My new RO/DI unit is knocking it down to zero, with an occasional reading of 1.

In your answers include Tap Water TDS, RO only TDS and RO/DI TDS. Those numbers tell you how effective your RO membrane and DI resin are. Without an RO number the info is only partially useful. Any good DI filter should get you to an indicated 0 TDS at least for a short period of time. The RO only is the workhorse of the system and determines how well things work and how long they work.
