Infinite RO/DI water

[Anemesis]

Ok i have a Vertex; Puratek RO system that i haven't change 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.

You probably have decent water going in and I would bet that you flush the membrane. What is the tds before any filtration and after RO but before DI.

Use the meter you suspect may be faulty. That reads TDS.

It says OOPP still that's my concern if its accurate.

Get a new hand held meter and compare the results. They are cheep and can usually be found at the hardware store.
