    Need to Always Backwash

    Hi everyone,

    Here is my problem, I have a Pentair TA60 clearpro filter a summit heater (sum3 titanium) and a Pentair superflow pump.

    My problem is that after doing a backwash my pressure is around 25 psi.

    When it its around 27 psi, my heater stop working telling me not enough FLOW as message.

    So now to heat the pool I need to backwash once or twice a day......

    Could someone help me, is 25 psi normal pressure or is it to high, another thing I've notice is that if I close my bottom drain and keep only skimmer the pressure goes down to 22 psi.

    Thanks.

    Hi, welcome to TFP! I have a few questions for you. Is this a new problem, or has this been happening for some time? How long do you backwash? How much does the pressure drop after backwashing?

    Re: Need to Always Backwash

    Hi thanks for quick reply,

    My pool is new from last year, same things last year.

    Pressure drops only from around 2-3 psi after the backwash (around 2 minutes), because I do them so often so I can use the heater, otherwise heater stop with flow message on display.

    I tried to remove around 30 pounds of sand (thinking pressure would drop more in filter so my heather would run longer) but it is still the same

    Welcome to TFP!

    I'd suggest you run your filter set to recirculate to see if the problem is with the filter or the plumbing. If the pressure is substantially lower on recirulate than it is on filter, make sure you are backwashing for at least 3 to 4 minutes.

    Re: Need to Always Backwash

    Try a good, long backwash then rinse for about 2 minutes and see if that helps.

    If water out direct to pool from skimmer, pressuer 19
    If water out direct to pool from drain, pressure 21

    If water out to pool by heater from drain and skimmer, pressure 24.5
    If water out to pool by heater from skimmer, pressure 22
    If water out to pool by heater from drain, pressure 23.5

    If i leave water to pool by heater from drain and skimmer, tomorrow at noon I will have flow message on my heater.

    Re: Need to Always Backwash

    Hi everyone, so I still needed to backwash again today

    I was thinking of changing my laterals in my sand filter to normal ones instead of the ClearFlow ones.....

    Do you guys think my pressure (Flow) will be better with normal Lateral?

    Thanks to all of you for your help.

    Re: Need to Always Backwash

    I'm not sure what the normal pressure drop across the filter with the Clearpro is but it doesn't seem too high.

    Did you ever figure out what size eyeball you have?

    Try taking the eyeball fitting out of the return and see if that helps the pressure and flow.

    rejeanc,

    What does your water look like? It's important to eliminate ANY water quality issues...your filter might REALLY be doing what it's supposed to and the gauge is faulty.

    Re: Need to Always Backwash

    My water is great.

    I really think it's the ClearPro laterals that causes the pressure to be so high, The flow is not very strong in the pool so I'm sure it's not a faulty gauge.

    My real problem Is because I need to backwash every day (other wise flow waring on heather), it's the second time this season that I'm adding salt and alcanality, I'm wasting a lot of water because of the backwashing...

    Does anyone have experience with ClearPro technology from pentair?

    Thanks to all!

    Re: Need to Always Backwash

    How about posting a set of test results and how you got them?

    The fact that your pressure is rising 2 psi per day is an indication that it's filtering something.

    Thanks to all for your help.

    When I remove the eyeball I still have the same issue.

    Does anyone have any experience with ClearPro technology from pentair?

    Thanks again.

    You can contact a Pentair tech directly at Pool fyi Monday through Friday. Usually you will get a same day response.

    Re: Need to Always Backwash

    need those test results as requested. You're filtering something out. These filters aren't much different than a normal filter. If you changed the laterals the problem would probably go away, but only because you would not be filtering as well.

    If water out direct to pool from drain, pressure 21

    If water out to pool by heater from drain and skimmer, pressure 24.5

    Looks like Bama is asking for water chemistry results.

    Re: Need to Always Backwash

    Looking for water test results (and how you got them). We need:

    FC
    CC
    pH
    TA
    CH
    CYA

    This will help eliminate water quality issues.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.
