And that's why you can run a dual DI without an RO membrane in parts of the PNWTDS is 14 in 0 out, Portland OR
2 tds from tap, 0 from to unit
Same place I get my water. Never had issues. Carlisle pa.Tap is 200 here in Eastern PA. I am currently using ro/di from the Weis grocery store.
I have handheld tds meter and my unit has one built in. I notice i don't burn through a lot of filters which is always a plus. I am just happy to get 0 tds coming anyways lol. My tank is always crystal. I was debating whether the use ro di, or tap water with prime to fill up my 220 gallon tank. Glad i went rodi.
You are definitely not wasting your time. ro di get's rid of metals, chlorine, chloramine and other contaminants so it is very useful. I use to be in the same boat when i saw low low low numbers from my tap. I said maybe i don't need a ro unit if i am getting 2 tds. Well i never regretted my purchase of my ro di. Mine has a di bypass which i use to fill up and for emergencies, picnics. You can call your town and ask them what they use to treat your water. But i can definitely vouch for ro di unit.West Winfield NY
When I first turn it on the in is about 3ppm after running its 0ppm going in. So I didn't use a ro/di system cause I didn't see the point if my water is already 0ppm tds. Im now having algae problems which I think is because I'm using tap water. So now I'm using the ro/di am I wasting my time?
