Hi i set up a 40/40 ro and 22l di system with a pump a short time ago,it has been making 100L PURE water in about 35 mins and the WASTE was 125L. Can anyone tell me if these amounts and time are ok. Also how much will 1000L cost on the water bill so i can put some money away for the bill. I thought wfp was going to be so easy,found it to be alot harder than it looked, THANKS
