  • 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).
        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 water based lubricant.
    – 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”:
                    Re-check strainer housing cover and all threaded connections for suction leaks. Check if all hose clamps are tight.
                    Check voltage to ensure that the motor is rotating at full RPM’s.
                    Open housing cover and check for clogging or obstruction in suction. Check impeller for debris.
                    Remove and replace shaft seal only if it is leaking.

  • Low Flow – Generally, Check For:
  • – Clogged or restricted strainer or suction line; undersized pool piping.
    – Plugged or restricted discharge line of filter, valve partially closed (high gauge reading).
       How to correct: Sand filters – backwash as per manufacturer’s instructions; D.E. filters – backwash
    – Air leak in suction (bubbles issuing from return fittings). Re-tighten using Teflon tape.
    – Plugged or restricted impeller or impeller sheared off. Replace including new seal assembly.

  • Noisy Pump – Check For:
  • – Air leak in suction causing rumbling in pump.
    – Cavitation due to restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge return lines. Correct suction condition or throttle return lines, if practical. Holding hand over return fitting will sometimes prove this point or putting in a smaller eyeball fitting.
    – Vibration due to improper mounting, etc. Put a rubber pad under metal mounting feet.
    – Foreign matter in pump housing. Loose stones/debris hitting impeller could be cause, remove any of the above
    – Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage, which will allow chlorinated water to seep into bearings wiping out the grease causing bearing to whine. All seal leaks should be replaced at once.
    – Equipment base vibrating.

    Frequently Asked Questions:

    What are the measurements of the pump?
    – Yes, this pump will work for you. By removing a clip behind the strainer basket and removing four bolts on the back of the motor, this pump can be changed from top to side discharge.

    What size pump should I use on my pool?
    – When sizing a replacement pump, In The Swim 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.

    What is the manufacturer's model number for this pump?
    – The manufacturer’s model number is SP1580X15.
