hi chaps, do i flush this system for the recommended 15 mins every time before use?
Our water isn't too bad and doesn't contain much calcium unless you live in Hartlepool or vicinity.

I used to flush my 450gpd r/o once a week for 5 minutes if I remembered. The membranes lasted 6 years. I can't remember when I last flushed my 4040. The membrane is going on 9 years old (fitted July 2012) with a rejection rate of 97%.

I flush mine for 10 minutes first thing in the morning and 5 minutes last thing at night, my membranes last approx 2-3 years.
