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.

yes got new filters in it

Whats the pressure? Do you have a booster pump?

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.

How often should membranes be changed on a 4040 ro??
