New pool pump motor is rattling


This really sounds like a motor going out. I would take it to a motor shop and have them check the bearings.

I have an air leak in intake line


Question:

What do I do if my pool/spa pump is loosing suction or prime?

Answer: by Osko Pool n Spa Pool Pump Losing Suction or Prime If your Swimming Pools Filter system looses Prime, it is caused by one of the following conditions.
Note: The lost of suction/prime is caused a leak which in turn sucks air into the system. The lost of suction/prime will be anywhere from the Main Pool Skimmer(s) to the Pool Pump. It will NOT be from the Pool Pump to the Pools Main Return(s).
1) First make sure that your water level is high enough so that the skimmer is not sucking air.
2) Check the Pump Pot Housing Lid Seal and be certain that its completely sealing and is not
Sucking air into the system. Check the lid for cracks. If either condition is true, replace the Pump Pot Lid Seal and/or entire lid
3) Check all fittings, clamps and hoses from the pools skimmer to the Pools Pump Pot Housing for wear, tightness and leaks.
4) Check Pool Pump Pot Housing for cracks.
If everything aforementioned in good working order, the next thing to check is the Pump Pot Housing Main Seal and the Pumps Impeller and finally the pump.

5) While the Pool Pump Motor is running, carefully inspect the area where the Pump Pot Housing attaches to the Pump Motor. See if there is any water leaking. Next, spray the area with water and see if the water is sucked into the Housing. If so, your Main Seal is damaged.
6) Disassemble the front half of the Pump Pot Housing from the back half and inspect the Pump Motor Impeller. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged.
7) Re-inspect the Pump Pot Housing Main Seal by standing the partially disassembled upright, with the Pump Motor towards the ground. Pour water over the impeller and into the cavity. See if the water leaks thru to the outside of the Pump Pot Housing. If so, your Main Seal is damaged.
8) Remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged.
If everything seems to be in good working order, then you need a new pump... not just replacement parts

I have a proline 1.5hp pump need to replace the shaft seal. I can't seem to get the plastic impeller off. We use a screwdriver to hold the shaft screw and try to turn the impeller counter clockwise...


Keep trying - It is stuck and will likely break but you have to remove it to change the seal. It is not uncommon to need to replace the impeller when the seal fails since the water gets behind the impeller shaft and rusts the metal causing the impeller to bind. If you still cannot get it free pull the motor thru-bolts and lock the rotor once removed from the motor in a vice. Use a large pair of channel locks to break the impeller free...replace it if necessary.

I cannot start pumping. the pump runs but no water is circulating


I think you have spun the center out of your impeller. Disassemble your pump and replace the impeller if necessary. Also replace all seals while you are at it.

Winding noise with some water leaking from the motor seal. Water still flowing but sounds laborous.


The shaft seal more likely than not needs to be replaced. If your shaft seal has been leaking for any length of time, the bearings could be damaged and this should be replaced. The whisperflow uses a PS1000 shaft seal and is fairly easy to replace (most seals available online or at most swimming pool retail stores). It is best advised not to run the pump until you have had this inspected by a licensed pool technician or have changed out the seal.

1) Make sure breaker/power to pump is off. 2) Remove the six bolts holding the wet end to the seal plate. 3) Remove the diffuser to expose the impeller. 4) Remove the screw in the middle of the impeller by turning clockwise (left hand threads). 5) Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. 6) Once the impeller is off, remove the four bolts holding the seal plate to the motor. 7) Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. 8) Apply a thin coat of lube (I prefer Magic Lube or Lube Tube) to the seal plate and impeller where the new seal will go. 9) Remove the new PS1000 shaft seal from the box (being careful *NOT* to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. 10) You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. 11) Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. 12) Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.
Check the pump for operation and you should be good to go!

How do you remove the impeller and mechanical seal off the pump shaft? I am wanting to change the main bearing that sits inside the motor housing of a Onga pool pump PPP750 model.


The impeller is screwed on to the shaft, you need to pull the cover off the end of the motor opposite the pump so you can hold the shaft to keep it from turning. The impeller should unscrew with just hand pressure, most are a standare SAE thread and turn counterclockwise to remove. Hope this helps.

Plastic impellor sticks inside on onga pool pump and i can't get free .When i try with phillips head screwdriver it is jamming and i can't loosen to get impellor off and the pump only makes noise and can't...


Your Onga Pool pump was running dry causing the
impeller to melt down and stick to the pump case.
You have to remove the impeller, and the only way
to take it off by using the heat gun to melt the stucked plastic impeller. Or by forcing it off slowly, cutting the impeller using hacksaw, taking care of the mechanical seal and the motor shaft not to bend it. Afterwhich you can replace the impeller, and assemble the Onga pump/motor. Then, you can
install the Onga pump back to its location. Just
send you e-mail for further assistance. God bless
you.

Onga jsp 130 leaks


It is leaking due to a defective mechanical seal. It needs to be replaced. To replace it, is to take the pumpcase
off by taking off the bolts that hold it. Then, take the impeller off to take the mechanical seal behind it. Put the replacement in, and reassemble the pump. Just get in touch with us by e-mail to get more assistance.

I have a jacuzzi magnum 1500 pool pump which leaks. I changed the O-ring and it still leaks. If I have to change the seal on it, how do I change it. I tried undoing everything on this pump. Thanks!


You need a 201 seal for the pump. Most electric motor shops that work on pumps and of course pool store carry these. If you are unfamiliar with how to change the seal, the charges to have it done are usually low. We charge $15 - $30 depending on how much of the pump is brought in and therefore remains to be taken apart to replace the seal. The seal is about a $5 item.

If trying yourself, you will need to completely disassemble the pump, lock the motor shaft at the rear of the unit, spin off the impeller, and replace both halfs of the seal.
