low pressure on ro

[smokinreefer]

just an update, maybe it will help someone down the line....
having my pressure drop down to near 15...i realize it is time to change something. i had already tested all the lines and removed a badly kinked liine, but no change.
figuring it was the discolored 1 micron sediment filter...i replaced it. still no change. it was the carbon filter, second in line that was clogged up.
so i replaced that and all is well, back to 60 psi.

is it common for the carbon filter to get clogged first?
it just doesnt make sense to me...
the first filter is a 1 micron sediment filter, and the second is a 2 micron carbon filter...it only seems logical that the particles going through the first filter are 1 micron or less, so theoretically, shouldnt it take quite a bit longer for the 2 micron carbon filter, that is second in line, to get clogged up?
