Title: RO Question?
Post by: D.Salkeld_Ltd on October 13, 2006, 08:47:57 pm

Hi All,

When I first got my 100gpd RO man 5 stage RO it used to come out of the RO into the DI at 002.  Now, 6 months on, it comes out at 008 - 009?!  I have changed the pre filtres and flush every week for about 10 to 15 mins. I have it running for 1 continuouse spell of about 4 days per week.

Any suggestions about what is happening would be appreciated.

Thanks
David Salkeld

P.S. The TDS of our tap water is 286

Does it have a final DI stage (blue) if so the resin may need replacing.

It souldnt be the membrane yet.
