      • No backwashing required

      Rated 5 out of 5 by from Superb Filter I bought this last month to replace an older Hayward and the filter is superb, runs fantastic, came with all the parts, even teflon tape was on all the threads on the fittings. Superb overall, I couldn't be happier.

      Rated 5 out of 5 by from Holy Cow! I am not one to ever write a review, but I always read them before I buy anything. I have been dealing with a cloudy pool for 2 years now. I have spent hundreds of dollars in chemicals and wasted water. No matter what I did my pool was always cloudy. I completely disassembled, cleaned, and replace the sand in the sand filter twice and still a cloudy pool. I would shut the pump off for a couple of days and all the debris would settle to the bottom. I would then try to vacuum and the return would blow it right back into the pool. I tried to vacuum to waste and I have went through thousands of gallons of water. I was about to give up on ever having a clear pool again and then I stumbled across this thing called a DE filter. I hesitated for about 2 months and then I just decided to try it. 24 hours later my pool was just clear enough to see a pattern on the bottom. 48 hours later, the pool was clear. 72 hours later the pool was crystal clear. WHAT? HUH? Yes, CRYSTAL CLEAR. Can you give this product a 100 star. Why didn't I do this sooner?

      Rated 5 out of 5 by from Filter system We recently needed a new filter system, I wanted the same kind as the old one and another pool store wanted double the cost, I did some research and In the swim was the best price in town and it was delivered in three days. Great company to order pool stuff from.

      Rated 5 out of 5 by from Just installed this filter. The pool was very dirty from a dog that fell in to it over the winter. It is doing great duty right now cleaning out all the dirt. The dog was rescued and is fine.

      Rated 4 out of 5 by from Cleans very well!! Cleared up my cloudy pool overnight! Now to figure out why there is white sandy like material on the bottom of the pool but probably have to empty and replace the D.E. Product inside the filter...
      Date published: 2015-06-30
      Rated 3 out of 5 by from Ok Compared to my previous one it is much easier to open up to clean out but it is a pain to get it to stop leaking. If you tighten it to much it leaks and the same if you don't tighten it enough. So it takes some extra time to get that right otherwise you will be spending a lotbof time adding water. The power is great circulates the water much better then the previous Hayward that I had.

    • Running at high pressures.
    • – DE coated with normal accumulation of pool dirt, algae, etc.
      – Bump
      – Overcharge of DE.
      – Bump – Drain – Recharge
      – Restriction in return line caused by small eyeball fitting.
      – Change to larger size fitting.
      – Partially closed valve on return line.
      – Open valve.

    • Drop off of return flow.
    • – DE coated with normal accumulation of pool dirt, algae, etc.
      – Bump
      – Pump strainer basket clogged.
      – Clean
      – Skimmer basket clogged.
      – Clean
      – Pump impeller vanes clogged.
      – Cleaning with a stiff wire brush through the pump strainer opening will usually work. Alternate method would be to disassemble and clean.
      – Air leak on suction side of pump.
      – Check cover gasket, hand knobs, hose, clamps, etc. Replace or tighten as necessary.
      – Electric motor running less than maximum R.P.M. (underspeed).
      – Consult pump and motor troubleshooting guide. Note: Most motor problems are due to: 1. Undersized or improper wiring. 2. Power cut-backs. 3. Combination of both 1 and 2.

    • Short Cycles
    • – DE loaded to capacity with pool dirt, algae, etc.
      – Bump – Drain – Recharge
      – Bumping Incorrectly
      – Slow down stroke – brisk up stroke. Repeat 6 times.
      – Bump handle bent.
      – Check and straighten or replace.
      – Pump output exceeds design flow rate of filter.
      – Check GPM/LPM output. Regulate pump GPM/LPM output to max filter GPM/LPM rating.
      – Presence of algae.
      – Super-chlorinate; Bump-Drain-Recharge as needed.

    • Short cycles – even after proper Bump-Drain-Recharge.
    • – Contaminated (clogged) Flex-Tube braids caused by: 1. Natural accumulation of chemical deposits (accelerated if chemicals are fed through skimmer). 2. Running DE charge too long with excessive amounts of live algae present in pool. 3. Operating filter without DE. 4. Operating too long without DE after starting pump. DE must be added as soon as filter if full of water and pump is putting out a steady stream. IMPORTANT: Testing a new pool plumbing system without adding DE will cause this type of clogging.
      – Clean tube nest (2 methods).
      1. Detergent Cleaning: Remove tube nest and hose down with forceful stream of clean water. Soak tube nest in strong solution of laundry detergent (such as Cheer) and warm water. Hose down again.
      2. Chemical Cleaning. This requires use of water and muriatic acid solution (or filter cleaner-type preparations) to chemically dissolve contaminates. Consult your pool dealer for chemical cleaning instructions.

      – Replace the gasket.
      – Loose bolts on tube nest plates.
      – Tighten Bolts.

    • Hard Bumping.
    • – Caking of DE under tube sheet. Sometimes caused by accumulation of sun tan oils, hair or floating particles that bind together in a clay-like form.
      – Bump-Drain-Recharge more often and reduce the use of oils.
      – Overloaded with DE. Sometimes happens when last charge of dirty DE was not properly drained.
      – Bump- Drain – Recharge more often.
      – Filter runs too long between bumping.
      – Bump more frequently.

    • DE leaking back to pool via skimmer or main drain.

    • Very short cycles when vacuuming.
    • – Very dirty water.
      – Bump – Drain – Recharge more often.
      – Presence of live, vigorously growing algae.
      – Add enough chlorine to control this growth – then vacuum.
      – Presence of alum or flocking agents, which will clog filter.
      – Vacuum so as to bypass filter. Avoid using flocking agents.

    • Motor won't start.
    • – Check for improper or loose connections, open switches or relays, blown circuit breakers or fuses.
      – Manually check rotation of motor shaft for free movement and lack of obstruction.

    • Motor cuts out - check for:.
    • – Wiring, loose connections, etc
      – Low voltage at motor (frequently caused by undersized wiring).

    • – Make sure pump/strainer housing is filled with water and that cover gasket is clean and properly seated. Tighten hand nuts
      – Make sure all suction and discharge valves are open and unobstructed, and that pool water level is above all suction openings.
      – Block off suction as close to pump as possible and determine if pump will develop a vacuum.
      – If pump does not develop a vacuum and pump has sufficient “priming water”.
      – Tighten all bolts and fittings on suction side.
      – Check voltage to make sure pump is up to speed.
      – Open pump and check for clogging or obstruction.
      – Remove and replace shaft seal.
      – If pump develops a vacuum, check for blocked suction line or strainer, or air leak in suction piping.

    • Low Flow – Generally, check for:
    • – Clogged or restricted strainer or suction line; undersized pool piping.
      – Plugged or restricted discharge line of filter (high discharge gauge reading).
      – Air leak in suction (bubbles issuing from return fittings).
      – Pump operation underspeed (low voltage).
      – Plugged or restricted impeller.

    • Noisy Pump – check for:
    • – Air leak in suction causing rumbling in pump.
      – Cavitation due to restricted or undersized suction line and unrestricted discharge lines.
      – Correct suction condition or throttle discharge lines, if practical.
      – Vibration due to improper mounting, etc.
      – Foreign matter in pump housing.
      – Motor bearings made unserviceable by wear, rust, or continual overheating.

      Filter Sizing Advice
      To ensure proper filtration and a trouble-free season: Your pool's size (total gallons) should be equal to or less than the Maximum Pool Size listed for each of our systems. Maximum Pool Size is based on an 8-hour turn-over rate.

      Since our high efficiency systems completely turn over your pool water in less time than standard 12-hour systems, you save money by running your filter less!

      When sizing a replacement pump, Dr. Pool strongly suggests that you replace with the same size horsepower as your existing set-up! In most cases, up-grading horsepower shortens your filter’s expected life and voids manufacturer’s warranties.
      Filter Information
      No matter how you look at the Perflex Extended-Cycle D.E. Filter System from Hayward, it's a clear winner. No other filter gets your pool so clean, so fast. and with so little attention. Best of all, Perflex's efficient first-time-through cleaning power reduces energy costs because you operate the filter for shorter periods. Which makes operating a Perflex as easy on your wallet as it is on you.

      • Catch all the latest dirt with Perflex
        Particles of dirt that elude conventional filters can't hide from Perflex. Its deep cleaning power removes microscopic dust and pollen as small as one micron - one hundred times smaller than a grain of salt. Leaving nothing but clean, pure, sparkling water for you and your family to enjoy.

      • Efficient one pass cleaning power.
        When particles of debris do show up, Perflex gets rid of them the first time through. So you can run it fewer hours per day, instead of running up your electric bill. You also won't spend time and money running to buy D.E. powder. Perflex's small appetite for D.E. means you'll need just three or four charges per season, as each charge lets you operate your pool up to four weeks.

      • Perflex's strength: it's all in the flex.
        Unlike conventional filters, the Perflex design incorporates unique Flex Tubes. D.E. filter powder automatically coats these patented tubes, and traps dirt and impurities as they're pumped through the filter. But here's the exciting part. When accumulated dirt causes pressure to rise and flow to decrease - the time when conventional filters need backwashing - Perflex gives you a handling on the situation. By gently moving its unique "Bump" handle up and down a few times, you'll automatically activate the Flex-Tubes. This repositions the dirt and D.E. within the filter, and extends the filter cycle. Freeing you to do more important things, like swimming or just relaxing.

      • No backwashing required.
        Three or four times a season, just "Bump", drain, and recharge your Perflex with fresh D.E. powder. It's that simple. And since Perflex cleans without backwashing, you'll save hundreds of gallons of treated pool water, and eliminate the problem of waste water disposal. While conserving your own energy as well.

      • Give yourself the gift of time.
        Your Perflex system is performance-tuned to the Power-Flo series of high-power, energy efficient pumps. Also available on some systems is the Power-Flo Plus the first fully-integrated pump and timer that lets you operate you filter system whenever you desire - automatically.

      • Still sparkling after 25 years
        Proven over many years by millions of satisfied customers, Perflex offers the best performance and value in swimming pool filtration. You'll enjoy convenience and dependability, year after year, thanks to its superior design and corrosion-free construction. But best of all - you'll enjoy the crystal clear, sparkling water it creates. See it for yourself today at your local Hayward dealer. Isn't it about time you had an absolutely Perflex day?

        For proper filtration of residential swimming pools, your filter system should provide a complete turnover of the pool water once every 12 hours. Determine the capacity of your swimming pool to select the correct size Perflex system, or consult Dr. Pool. Because Perflex filters are designed for high efficiency, you may use the 8 hour turnover rate and save energy costs by operating the system less hours.
