Ro/di
Looking to add to my vertex Ro/di 100 gpd with booster pump system. My inlet tds is 900 to over a 1000 soft well water with a newer membrane it gets it down to 60 now being over a year old it's 240 tds so I use a lot of di resin to get it to 0 I want to add another membrane to get tds lower before it reaches di. Any suggestions ?
