I have a Starite Posiflo II PTM135 filter that spans 41" tall. Whenever I clean it, I only see dirt, leaves, whatevers, on the bottom 1/3 of the filter; the top appears to be clean.
I want to build a protective shed around it, and 41" is too tall. In looking at my filter today, I thought about possibly eliminating the center section, and this reducing my height by 14". I can loosen the tightening rings, remov ethe center section, and attach the top section to the bottom one. Naturally, I need to buy a smaller cartridge, which I am still looking for; I assume that it exists - same diameter as my current one, but shorter. I found this one, Sta-Rite PXC-175, at 28 3/16" tall wiht the same diameter, that may work. If you look at the attached pic, you will see what I have (on the left), and what I want to achieve (the one on the right).
Am I crazy for trying to do this? Can some of you kindly convince me in favor or against? In theory, I shouldn't lose any suction or return power, right? I have a 16k galloon pool, with a 1.5 hp pump, and I use my navigator pro cleaner as my main source of intake; if the water level allows, I switch to skimmer.
