Reverse Osmosis Question...

Hi All,
This is a simple tech question regarding a Reverse Osmosis System....
Recently I've purchased such a system of 100GPD. At the beginning the output
was really 100GPD, but now it works with 85GPD even after I've replaced the
Filters. (One Pre and two carbon filters....)
I can add that the water quality is great and I use the system quite often.
Is this a normal decrease in such systems ?

Thanks,

A.B

IME yes, the RO membrane will slow a litttle as it ages. Also, your supply
water pressure plays a major role in your GPD.
