ok, my tds going in RO from outside tap is reading about 350. coming out of RO reading about 020 and has started to creep up.
coming thru DI at 000 but this is starting to creep up to 001.
are these readings normal or do i need a new membrane? or just change resin again? (i changed prefilters about a month ago)
would a booster pump help?
cheers

when is the last time you changed your resin as RO reading from 350-20 seems pretty good to me, so i'd question the resins work myself whether its past its best. Resin thats OK would strip it to 0000 I'm sure.

a higher pressure would lower the tds before di.


i had 370tds going into 450gpd ro-man at a 105psi tds before di was 6/8

changed resin in june - have an 11ltr vessel and used tulsion bought from pure freedom.currently produce about 1300ltrs of water per week.
the best reading  ive had so far is 018 from RO - having said that, it always hangs about the 020 to 025 mark? ive had it since feb and its been regularly flushed.
always had 000 from DI tho and changed the resin for the first time in june.
any thoughts??
