tds still about 60 Will a booster pump make all the difference how much are they and where do you get them. Not sure if it will be cost effective for me as im only going through around1000 lts a week at the moment. Is this tds normal this high andrew or ian? also noticed memebrain had no rubber seal on end of old or new one? Hope thats the norm also guessed it was they both looked the same?
The only time a softener would make the TDS high is if there is still a saline solution produced when regenerating the softening resin. You MUST make sure you give it time for the salt solution to be totally removed. Make sure the softener IS NOT connected to the van/RO system while you are regenerating the resin. Good advice from Ian as well about filling the salt vessel 2 or 3 times each time you regenerate your softening resin.A decent booster pump for a 40 inch RO is around £200.00.I am really suspecting very low water pressure for you only to get down to 60 TDS. Also if you are only filling up a couple of times a week disconnect the inlet to your DI and run your RO output water to drain for 10 to 15 mins and then hook up to your DI again. You will be getting TDS creep into the RO and when you first "fire it up" the output reading will be high.Andrew
