Infinite RO/DI water

[basile]

Ok i have a Vertex; Puratek RO system that i haven't changeRO filters in 2 years of continuous use. And the particule reader indicates 00PP still.

I haven't change the membrane either , just the carbon and pre-filter once in 4 years.

So do you think my meter is faulty. Or my water is of good quality to begin with.

Whats your tds of your tap water or inlet water

its OOPP but thats what i'm wondering if its accurate. after 4 years straight.

There is no way tap water is 00

For sure.... mine reads 594tds!!

I would definitely question the meter at this point... Unless you live in a medical lab that filters all its water to 0TDS! LOL!

I've been running mine for a little over 2 years now with no changes to the filters at all, still reading 00pp on my in-line meter. I even picked up spare filters for when they need to be changed, but I haven't needed them yet. Then I measured the TDS of the tap water with a different meter and it was only 15ppm (measured several times to make sure). I'm guessing that my building has filter on it of some kind. But it does seem possible to have really long filter lifetime if your incoming water is also pretty clean. Not everyone is so lucky, it seems.

I would get a handheld meter and get a cup of your tap and a cup of your rodi and check them. See if you still get same results. If you do...you dont need an rodi unit and I am moving next to you!

I have a RO/DI and its OOPP still after all that time. We do have very good water in Ottawa but i'm concern about the TDS meter's accuracy after all that time i should have to replace the DI filter.

What is the TDS before running through the RO/DI? That is what was asked above too.

Dunno, will have to buy TDS handheld meter to find out.

Mine is zero after carbon canisters & RO membrane. But straight from the tap it's usually under 50 so my system doesn't have much work to do. Just saying zero before DI is not necessarily suspect.

Get a good handheld ATC temperature compensated TDS meter. Something like the HM Digital TDS-3, TDS-4TM or AP-1 are good inexpensive choices and they serve dual purpose too since they have a digital thermometer built in.
Test your tap water, your RO before it reaches the DI and your final RO/DI TDS. I seriously doubt what you have is accurate.

I've already ordered my TDS and it'll be arriving monday i'll post the result monday.
