have you replaced the pre filters? that can slow production down.

I have the same system, mine is over 4 years old and still on the original RO membrane. It does slow up if you don't change the pre filters, i always change them every 3 months.

I think it also has something to do with water tempereture, as the colder weather comes, production of water slows down, even with booster pump.
