di or ro what is the difference?

go look it up on google : :

DI is making the water pure via running your water though a tube of resin beads

RO is making your water pure though a membrane

you will still need DI after the RO to give it a final polish

There is so much info on here.. you really do wonder why dont people search and read a bit and learn? Its not like technology is gonna change in the last 2 weeks or make that days..

Expect to see more newbie posts asking the same questions over and over again

You can see from peoples replies recently - going from sentences to words how many people are getting irate at the same questions coming up time and time again.

Is it me or has a lot of experienced guys seem to have disappeared (stopped posting) recently?

it will depend on your TDS reading wether you need to use a RO or DI. Depends on where you are in the country.

I agree there are a lot of posts asking the same questions over and over again, but from my experience finding old posts can sometimes be a bit of a struggle.

I think it would be good to have a 'sticky' post at the top of the forum explaining where you can find out stuff like this. ?

There was a post on here a long time ago - maybe from Alex - indicating where the 'cutoff' point is between using a DI or an RO. It was to complicated for me to understand at the time and, as I use an RO because our water is a TDS of about 250, I didn't bother to try to work it out.
It might be a good thing if the Newbies might try and find it so they know what to expect.
For example, resin will last much longer with an input TDS of 20 than it would with an input TDS of say 60.
