      • – Check skimmer and pump strainer baskets for debris.
        – Check for restrictions in intake and discharge lines.
        – Check for air leak in intake line (indicated by bubbles returning to pool).
        – Backwash filter.

      • – Check for algae in pool and super chlorinate as required.
        – Be sure chlorine and pH levels are in proper range (adjust as required).
        – Check surface of filter sand for crusting or caking (remove 1" of sand if necessary).

      • – Check chlorine, pH and total alkalinity levels and adjust as required.
        – Be sure flow rate through filter is sufficient.
        – Operate filter for longer periods.
        – Be sure multiport valve is set on "Filter" position.

      • – Check laterals, standpipe and lateral hub for damage (replace as required).
        – Be sure there isn't too much sand in the filter itself.


      • Motor Will NOT Start – Check For:
      • – Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCI's, or blown fuses.
        – Manually check rotation of motor shaft for free movement and lack of obstruction.
        – If you have a timer, be certain it is working properly. Bypass it if necessary.

      • Motor Shuts OFF – Check For:
      • – Undersized wiring; loose connections; etc.
        – Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).
        – Mechanical binding and electrical overloads.
        NOTE: Your Hayward pump motor is equipped with an "automatic thermal overload protector." The motor will automatically shut off if power supply drops before heat damage can build up causing windings to burn out. The "thermal overload protector" will allow the motor to automatically restart once the motor has cooled, provided the power source is again up to proper levels. It will continue to cut On/Off until the problem is corrected. Be sure to correct cause of overheating.

      • Motor Hums, But Does NOT Start – Check For:
      • – Centrifugal switch stuck in OPEN position.
        – Binding of motor shaft.

      • Pump Won't Prime:
      • – Make sure pump/strainer housing is filled with water and the cover O-ring is clean, also be sure it is properly seated in the cover O-ring groove. Make sure strainer cover is locked firmly in position and lubricated with "Jack's 327."
        – Make sure all suction and discharge valves are fully open and not blocked, that pool water level is at proper level, and that skimmer weir is not hung up or binded on skimmer wall.
        – Block off to determine if pump will develop a vacuum. You should have 5"-6" of vacuum at the strainer cover (Only your pool dealer can confirm this with a vacuum gauge). You may be able to check by removing the skimmer basket and holding your hand over the bottom port with skimmer full and pump running. If no suction is felt, check for line blockage
        – If pump develops a vacuum, check for blocked suction line or dirty strainer basket, an air leak in the suction piping may be the cause.
        – If pump does not develop a vacuum and pump has sufficient "priming water":
        1. Re-check strainer housing cover and all threaded connections for suction leaks. Check if all hose clamps are tight.
        2. Check voltage to ensure that the motor is rotating at full RPM's.
        3. Open housing cover and check for clogging or obstruction in suction. Check impeller for debris.
        4. Remove and replace shaft seal only if it is leaking.



      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.

      • Energy Savings
        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 Pro Series 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.
