well cant believe it guys its not been long since my last posts and changing my resin and checked it a few days ago it was 2-3 ppm then this morning right up to 12-13ppm so its creeping up, surely this isnt right starting to rise in little over a month.my tap water is only 75ppm so its not like 2-300 like some people use, i finished the day off as its weekend and i know the windows have dried perfect.have i got a bad batch of tulsion mb115 or something as my other bags seem to have lasted longer than this?
Personally you would be better off with an RO long term I was RO for about 4 years then switched to DI only now going back to RO in the next few weeks . Loads easier and loads cheaper . Mike
