    Cartridge filter cleaning, a lesson learned

    Thought i would share a little fun i had today. You see, the last pool guy that i had said that we should clean the filters when the pressure gauge starts to rise..., no need to do it more than that. After a series of dramatic events, we found a new pool guy . The new pool guy informed me that the filters should be cleaned about 2x per year. I figured that since it had been 2 years since the last cleaning, it was time, the picture tells the rest. Flow is much improved

    (sorry about the rotated images)

    Wow, yeah it was just a tad bit dirty for sure. On the bright side, it cleaned up nicely, though.

    Yah, i was pretty disgusted. Even the pool guy was like "wow, i'm surprised your pool looks so clean!" (he stopped by when i was in the middle of this). Question, how long on average do these filters last?

    If your pressure gauge does not register a noticeable difference after cleaning those filter cartridges you should replace the gauge.

    I use a Hayward C1200 filter with similar style cartridge. Even with a pressure gauge, I make it a habit to rinse my cartridge out about once a month - especially in the summer when the bugs and swimming is at their peak. Good thing you looked for yourself.

    Hi timbozi,

    Everyones cleaning cycle might be a bit different. Just depends how much stuff gets into the pool and how large the filter is.

    For some folks, cleaning it twice a year may be fine, for others, they may need to clean it each month.

    Using time as a measure to know when to clean your filter doesn't really offer much in terms of whether the filter needs cleaning or not.

    TFP recommends cleaning your filter when the pressure rises about 25% above the "clean" pressure. Here is a link which is located in Pool School about it.

    Used a brass sweeper nozzle (Amazon and HD have them). Placed the filter on top of an inverted 5 gallon bucket and sprayed top to bottom in sections, rotating the filter. Problem now is that my lawn is going to think that i want it to grow...

    OK, it's never risen above 10 psi, will look into that.

    Re: Cartridge filter cleaning, a lesson learned

    That's exactly how I clean mine as well. I've tried the TSP/dishwasher soaking to try and extend the life of a filter, but by the time I was done with all of that, it was just as easy to order a new filter on Amazon.com.

    Now I see from your other post you have the quad-filter set-up which is why you can get by with longer intervals between cleaning (along with watching the pressure). I just a have a single cartridge, so mine fills-up a bit sooner. Nice looking pool on your other thread.

    TFTestkits.net (as well as some other vendors) sells some really nice replacement gauges that have a higher degree of precision. You want to get a glycerine-filled pressure gauge that reads 0-30psi in 0.5psi graduations. Glycerine is better than water, as it does not freeze and it's higher viscosity keeps the needle from bouncing around.

    Re: Cartridge filter cleaning, a lesson learned

    I just got one of those glycerin gauges from tftestkits..they are fantastic and not much more cost than a standard gauge.

    I was annoyed by the bubble at the top of the gauge, but for my sand filter, the bubble left and right
    edges are exactly where the needle should be after a backwash is done and on the right where it gets to when its time for a backwash.

    convenient!

    I have one of the glycerin filled gauges too. I love that thing. Much much better than the cheap OEM one.
