    Too many variables. But one of the worst things you can do for a cartridge filter is to clean it too often, it shortens the life.

    Any hard evidence of this? I clean about 3 times a year, lot's of leaves and tree debris.

    Just experience. The high pressure hose nozzles take a toll on them and it tends to cause the bands to separate from the pleats.

    You should never use a high pressure nozzle to clean your cartridge. Buy the simplest, cheapest nozzle that you can find. You are looking for a pencil sized stream but not lots of pressure. Hold at 45 degree angle and wash the debris away. Never point straight into the filter if you can avoid it.

    To avoid the need to clean so often, use a skimmer sock to catch the debris before is gets to the filter. There are many different types of skimmer socks available including pantyhose, paint bucket strainers, and hairnets.

    I disagree. I don't mean a pressure washer but something that makes a very strong concentrated stream.

    I'm sure you can get by with a run of the mill nozzle but it'll take longer and require more effort to get the water deep into the pleats.

    thats a slick nozzle. I just replaced my cartridge this year, and I already cleaned it twice. I will monitor how gentle I do it.

    I used to use a brass nozzle which worked pretty well. Then I got one of these, Filter Flosser | Filter Flosser Cartridge Cleaning Tool It is a lot better. I prefer Pleatco filter cartridges to the OEM cartridges.

    thats another great looking nozzle. I use the Pleatco now as well. It was cheaper and the quality is great.

    Mine don't last more than a couple of years. I suspect sun screen lathered on the grandkids is a big part of the problem.

    Just curious, exactly how do they fail? Do they get clogged and you can't clean them anymore? Have you tried the TSP/Acid process?

    They will usually tear somewhere in between the pleats or the rubber hosing on each end may crack. At least that's what I have seen.

    Yes, I am aware of how cartridge filters normally fail. However, ChuckieChan indicated sun screen was the culprit so I am interested in why that would be in his case.
