junglejim Posted October 13, 2014 Report Share Posted October 13, 2014 Hello, I just bought a RO machine from Trademe and tested the water, it is 18ppm. Is this going to be ok to use or too high? Thanks Quote Link to comment Share on other sites More sharing options...
livingart Posted October 13, 2014 Report Share Posted October 13, 2014 too high, you should be aiming at 0 Quote Link to comment Share on other sites More sharing options...
Godly3vil Posted October 13, 2014 Report Share Posted October 13, 2014 Definitely too high, may as well use tap water pretty much. You'll need to replace the filters and membrane, di resin if it has some. Quote Link to comment Share on other sites More sharing options...
junglejim Posted October 13, 2014 Author Report Share Posted October 13, 2014 Arse.... It doesn't have a de-ioniser so will never get 0 Quote Link to comment Share on other sites More sharing options...

Adrienne Posted October 14, 2014 Report Share Posted October 14, 2014 No it is unlikely to get to 0 without the DI but my RO gets to 1 without it. Best to replace all the cartridges, test the water from the tap and then see how low the new cartridges can pull it down to. If so too high you might have to add the DI.

kinnadian Posted October 15, 2014 Report Share Posted October 15, 2014 I assume it was second hand? How much did you pay for it? Quote Link to comment Share on other sites More sharing options...
