Hey guys. I'm re-doing my 4-stage RO drinking water system and I realized the person who installed the system (about 15 years ago) did not plumb the post filter to the membrane and instead tee'ed the 3rd stage to my fridge and to my RO faucet...
Since I fear the person who installed my RO filter could be entirely wrong, does the RO filter work the best when the dirty water flows through the filter inwards to outwards (middle to outside of filter) OR outwards to inwards (outside to middle of the filter)? Thanks.
