I bought the RCB 3P 300 GPD system in Oct 2020. The system has 3 RO membranes ,MC-1, each rated at 100 gpd RO output. The unit feeds a 200 gallon storage tank and separate pump for whole house use. We use between 100-250 gpd- the average is 150 gpd. The RO water comes out at 10 PPM . I added a calcite tank to improve the taste . Capture ratio C= 52% . Actual measured RO flow is 320gpd. After 4 months we have used a total of 18,000 RO gallons. I believe the iSpring MC-1 membranes should last to 24,000 gallons. This is a real whole house system and very reasonably priced. Be sure to change your 3 prefilters at 24,000 gallons into the system. This will prevent any chlorine from damaging the RO membranes. Don at iSpring customer support - support@123filter.com - helped me to increase capacity and flow. I added a 4th RO membrane which Increased output to from 320gpd to 430gpd (see photo). The pump runs fine at 122psi . I used the existing 450 restrictor. RO pure at 15 ppm. Capture ration is 55%. This iSpring unit is amazing! I call it the “Little Engine that Could!" Next I will try to increase capacity by using the 150 gpd membranes. Don at ISpring support has given me excellent support!
