Title: Ro-DI Help needed please
Post by: wightsurf on March 26, 2008, 09:36:34 pm
Fitted my upgrade kit today on my 100 gpd ro unit,has mad no difference at all my presure is still 40 psi and out put of water is the same ! i was hoping this would push the psi up a bit and lower waste water. May be i should put new filters in but i can't find the coconut filter.I have found the Active carbon and the inline carbon and the 5 micron filters but not coconut  ???
I have checked and doulble check all the pipe work and it's the right way  :P
So i was wondering what is the waste water tds reading and why rather than run it down the drain why can't it be rerun back through the ro unit again,would this kill the prefilters quickly ? Or would it just not work and if it did work would it out way cost of prefilters to waste water ?

Yes a pump would defo help improve your output & this is not much help I know cos the pump would recommend is no longer available but you can get an alternative from RO Man have a look on their site for 100psi pumps

The pump will definitely make a difference.  I wouldn't think you will get any better than 50/50, if you do then your membranes will need replaced prematurely.
