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
