major probs with my RO-MAN - any ideas?
200g a day RO MAN system. TDS has been creeping up the past few days so i changed the filters yesterday, with some i had ready. TDS still high, so i put fresh resin in today, thinking that would solve it.
Reading is 12 coming out of RO, then it goes through DI and comes out as 34!!! i have no idea and am desperate - pleaaase help
