Question about Pentair 3hp Whisperflo Pool Pump In - Ground

1 Answer

I have a 1hp whisperflo (we24). It became noisy but was still pumping normally so I sent it to get fixed and they changed the bearings. When it came back the flow was down by about much that my salt system is telling me "no flow". They took it back and changed some screws that were broken but it just came back with the same very low flow. It looks as if the impellor is not seated properly. Any suggestion?

Their is a wear ring that goes on the front of the impeller. Be sure that is there and on right. Most people will put this on with the large side against the impeller but it goes on with the large side out. This is so when the pump starts it will slide forward and give you all the pressure you can get. Also make sure you have the "O" ring on the front of the diffuser. It will help to seal and divert the water in the direction it's suppose to go.
Without these on correct the water can go from the pressure side of the impeller around the diffuser and back to the front of the impeller again. Loosing up to 30% of your pressure.

Pentair WhisperFlo 1hp, 230v, Dual Speed won't start in morning

If the high speed side of a two speed pump will not operate it is because there is a problem with the windings on the high side of the motor.
You will need to either take it to a motor shop and have them fix it or replace the complete motor.

My WhisperFlo 2.0 HP pump is making a shrill sound, can I fix this issue?

More than likely, the bearings are going out on the motor. Usually you'll hear a loud screeching sound when this happens. You have 2 choices here. You can either take the pump to a local repair shop and have the bearings replaced, or you can replace the motor and pump seal. By replacing the bearings only, you're not guaranteed that the motor will last much longer. I always recommend replacing the motor and seal that way you'll be trouble-free for another 4-6 years.

You can have the bearings replaced for about $100. It is something that you will have done by a professional. Consult with a local pool store and they should be able to direct you to someone that does that.

More than likly it's a square flange motor. If the noise is just starting when you take the pump apart you can check the impeller for problems but the most likley is a bearing going bad from a seal leak. If you remove the wires and take the motor with the back half of the pump to a pool store they can diagnose it for you and do the nessary repairs at the shop. Usually they will do this for a small bench fee or for just the price of the nessary parts.

Pump is getting very noisy

It's possible your bearings are going bad. If you have or have had a shaft seal leak, the bearings will get progressively louder until the motor seizes. Then it will just hum. You'll need to replace the motor and shaft seal.

Motor is very noisy

Noisy motor indicates bearings on the shaft are going bad. This happens when you have a shaft seal leak and the leaking water is getting to the bearings. Sounds like you need to replace shaft seal and set of shaft bearings. Easy fix is to replace the motor only for about $150.00 for motor replacement. Around $40.00 for seal and bearings and some of your time.

Pool pump starts & stops on its own outside of programmed run

There are several potential problems:
  • freeze protection circuit causing pump to start - could be a bad outside air temperature sensor.
  • It is possible the new relay is bad.
  • There could be a short in the control wires to the relay
  • old programming shadow stuck in memory (not likely since you changed the boards)
Yes, the starting and stopping can harm your pump.
