I installed the filters and turned on the water. The system will normally begin to "spit out" water and air as it purges air from the system. This time I only heard the water gurgling for a minute and then nothing. I disassembled the system and found that the white activated carbon filter was missing part of the inner sleeve. It looks like parts of the liner and soot got into the lines to the next filter and blocked the passage. Cheap filters cost me my reverse osmosis system :-(
