    Hey all,

    Just a warning about these type of canisters when the FILTER CARTRIDGE IS CLOGGED and the PSI is much higher than normal.

    I had planned on changing my cartridge tonight anyway, but came home at lunch to find that the PSI had risen enough to start leaking at the lid seal.......

    Fortunately, it did NOT drain the 180 gallons on the floor thanks to the overflow weirs and the intake positions...... about 5-10 gals total...However if the drains were at the bottom of the tank, it could have been very ugly..................

    So cleaned up, replaced cartridge, etc no problems now.

    DO NOT PROCRASTINATE ON FILTER CLEANING.

    If you are close enough on the PSI to warrant you doing it 'in 1-2 days', my advice is to just do it!

    I was aware that a high PSI will cause a leak at the lid o-ring, but thought I had longer than I actually did.

    Lesson learned for me :)

    Well, I throttle my flow to give 5-6 PSI as per MFG recommendations.......

    I usually change mine when it gets close to 10 PSI. No more than 11 TOPS. And now sooner based on this experience LOL

    It depends on how tight the clamp is to prevent leaks at higher PSI, but I see no need for it to go > 11 PSI.

    While I tested it new at max of 18 PSI, I did not keep it there for long as I did not want to damage the seal at all. It was brief to see the max PSI.

    Hope this helps.
