hi guys, I bought the reach and wash last year, came with reverse osmosis but it's only a 4 stage one, sediment filter, carbon block filter, resin filter, then to another sediment filter, then it goes to my di vessel then to the hose reel out of my brush ( I have a 250ltr tank filled with tap water which goes through the ro) When I first bought it the bag of resin lasted me a while (I'm assuming it was unger resin) but then I had to buy a new 100 psi pump (baring in mind I don't have a pump controller) anyways I changed the filters in ro. But bought 10ltr of resin of eBay to be on the cheap side.. Supposed to be tulson from daqua.. Lasted about 2 days before smelling and tds went sky high... Same again yesterday ordered new resin and it's done same again, is it the quality of the resin? Is my pump too powerful for filters do I need controller? Or is my ro set up wrong even though it was fine when I first bought it?? HELPPP!!!!!
