My system consists of a centrifugal filter, a sediment filter and 2 carbon block filters. After replacing three entire filter cartridges around the house, there were air pockets in my lines that I couldn't clean. I had to remove the washable pleated filter and put the original mud filter back in the system to fix this problem.
