Hi all, Last year I bought a used Brodex Portapower trolley-had a few probs with it so started to do the rainwater harvesting method whilst I converted over from trad to pole which has gone swimmingly. Anyway, got to a point where it wasn't raining enough (yes, I know...) so I've got my trolley up and running with a new HF4-4040. I've installed a water softener vessel, then the water goes through a 150psi booster, then through a 20in Fibredyne Carbon filter then into my RO then into my resin. My tap water is 360-370ppm-it's coming out the RO at 17-18. Was expecting slightly better results than that as the RO is meant to have 98-99% rejection rate. I've played around with getting the right waste ratio. Currently running at 60% waste 40% product. Just checking if I'd set it up ok?!? Any thoughts. Thanks in advance.
