Question about Pentair Whisperflo 1 12 Hp Pool Pump Wf26 011773 ()

1 Answer

Have a pentair 1 HP whisperflow pool pump. It makes a loud high pitch sound when turned on. Sometimes when first turned on it won't but quickly will begin making the loud high pitch sound. Almost like it is starving for water. It also spirts water from the gasket seal plate when first turned on but fixed that problem I think. I took pump face off and noticed that the O ring that fits against the pot fit loosely but wasn't sure it that was normal.

SOURCE: wirng connecions for 110v pentair pool motor???

Next, as a suggestion. Purchase an Emerson Pool motor. The electrical connection is the same for 110/220 volts. All you have to do is move the switch by the electrical connections and select 110 or 220 volts. They usually come preset on 220 but I would check anyway. Also, don't forget the ground wire (green) and also connecting the bonding wire on the outside of the motor near the plastic cover for wiring. If you don't have bonding I would get it real soon! Hope this helps..

SOURCE: My Pentair legend pool cleaner is not moving

On this automatic pool cleaner, this is usually an easy thing to fix. First, make sure that your filter bag is clean and free of obstructions. Next, take of your head float and shake it. If you can hear water inside, you will need to order a new head float and install it. They are usually inexpensive and easy to replace. Make sure the hose floats are evenly placed and make sure that the cleaner is not getting too much pressure from the return lines.

Thank you for posting your question here on

It could be the pump is bound up but it is more likely the motor is failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.

You DO need a booster pump to power these automatic pool cleaners. It will not work without one.

Whisperflow pump making loud squealing noise

The noise is likely either the seal or a bearing in that order. If you are mechanically capable of working on the pump yourself then you can purchase a seal and gaskets at a pool supply store. If the bearings are bad then the motor needs to be replaced. In some cases a bearing can be replaced but usually it is more work than it is worth.

I'd suggest the 1.5 HP Hayward Super Pump, model SP2610X15. It's layout makes fitting it into the footprint of the Jacuzzi easier since it's ports roughly line up and are smaller in spread than the jacuzzi. Any pump will require some monor replumbing; the Haywards should be the least intrusive.

Another good choice would be the Pentair Whisperflow in a 1.5HP with or without the variable spped features.

Pump motor makes loud noise when pump comes on

If this is a high pitched sound, then this sounds like you have bearings that are starting to go out.  There is not much that you can do to prevent eventual failure.
The only other option that I see is that there is something causing friction inside the pump between the impeller and diffuser.
