Finally finished reading the last 30 pages or so. From the discussion of PoE, seems i can go to ace hardware and buy two the blue casing and make a 2 stage filtration? What about the filter? Where can I buy the filter? Any specific brand/model recommended? @hestati I saw a few pages back you have a complete system of PoE including the pressure gauge. Is it readily available? My house is landed so I’m interested in the 20” version.
