change 1st-2nd stage filter per 6-12 month, change membrane per 12-24 month, change DI filter per 300-400 gallons to keep a perfect performance This system could start to generate the pure water at 35PSI, and the best situation is 65PSI.
If the pressure of the incoming tap water is too low, you have to buy extra booster pump to get it work.
The Pre-filter can work for 6-12 months and create the 2000-4000 gallons pure water.
The membrane can work for 24-36 months and create the 54,000 - 110,000 gallons pure water.
DI filter works for 400-500 gallons.
GPD = Gallons Per Day (how many gallons of pure water can be produced per day)
All RO systems will generate not only pure but also waste water.
Normally, when using a flow restrictor (450 ML) with 65 PSI at 25 degrees Celsius, the ratio of pure water to waste water generated is 1:3.
