Post by: paul ette on August 21, 2013, 07:05:00 pm

i have a system that has 2 20 inch ro membranes on it, thought they needed replacing but read another post saying waste water should be 40 to 50 %, i had it set more like 20 and tds was coming out ro at 50. just adjusted the wastee to around 40 and now getting 20 tds from RO(NOT DI)
is this about normal?   tds from tap 250 to 300
