Do you match prices shown on and what would the cost be to replace a Pentair Whisperflo 1.5 hp (model #011554) pump? Would an installation kit be needed and if so, what is the price? Do you repair such a pump? I had a new pump installed 2 1/2 years ago and it is no longer operable?

A     Answered on 2/20/2017 by Scott W.

We do not price match Amazon. The 011514 is $569.99 and the 011554 is the model number for the 4000 Series Pentair filter not the pump. Were you needing any information about that filter? We do not repair or install anything. We can help walk you through the installation and we have instructional videos on our website to help you with that as well.

Has this pump always been made with threaded in and out ports that need a screw in type of fitting to connect the pvc? I have an older model and it leaks from the out port the one on top and I don't think the installer did it right because the 2" pvc goes straight in, no fitting just pipe. I'm going to cut it and do right but I'm afraid of it not having threads. The more I research it I betting that it must. Thank you

A     Answered on 10/18/2016 by Lennox H.

Hi, Rafael. I could not find any information stating that this pump did not come with threaded ports. It's rare to see a pump without threaded ports. If that's the case then you will have to replace the entire Whisperflo Pump Housing depending on how old you pump is.

20,000 gal pool. running 3hp VS pentair whisper with suction cleaner. I don't like this setup, because I have to turn off main drain and skimmer and then run pump at high RPM which takes away the VS advantage. I want to install another smaller pentair pump to only run suction cleaner, maybe a 1.5hp pump. That will allow me to run the big pump longer hours at lower rpm's. I was thinking about the WFE-26, but do you have other recommendations?

A     Answered on 9/13/2016 by Scott W.

Adding another pump also takes away the VS advantage of saving on your energy bill. If you are going to add an additional pump I would go with the Boost-Rite, which would be a booster pump for a pressure side cleaner. A great pressure side cleaner to go with that booster pump would be the Pentair Racer, part number 360228. The Boost-Rite is a great energy saving pump.

I have a 1 and 1/2 horsepower pentair's the actual pump that leaks. Can I buy just the pump portion..thx

You can buy individual parts for the pump, including the body, but the pump front half is not sold as a "set". Here is a link to the Pentair / Purex Whisperflo Parts list.

There are many models to choose from in a whisperflo 1.5HP. There is WF-6 (which is what I have now) this one is a WFE-6, and then I've also seen WF-26. Can you tell me what the differences are?

A     Answered on 6/7/2016 by Lennox H.

Hi Bryan, The WF-6 pump is a standard full rate 1.5 hp model which has a total hp of 2.25, the WFE-6 pump is an energy efficient version of the WE-6 pump, it uses less amps and the WF-26 pump is a standard up-rate 1.5 hp which means it has a total hp of 1.65. So the full rate models has a higher total hp because of the service factor.

I have an old dial based timer control for my WhisperFlo WFE-6 pump. I heard that to use this motor properly, I need to replace it with electronic timer control, such as Intermatic P1353ME. Is it true and if yes, what advantages I can get from this timer?

A     Answered on 4/20/2016 by Robert M.

Hello Dmitry - A simple dial timer is all you need for a single speed pump like the WFE-6. A digital timer like the PE1353ME would be ideal for 2-speed pumps or if you wanted to connect other equipment to the timer.

how much energy do you save with a whisper flo compared with intelliflow, please?

A     Answered on 7/19/2015 by Hector F.

This will depend on exactly which model whisperflo you are referring to and the energy costs in your market. Here is our "how to calculate the cost of running a pool pump" page that can assist you in calculationg those comparisons.

My whisperflo 1.5hp 1.10 sf model wfe-26 stopped working is this 220 or 110? will the itellaflo swap in

A     Answered on 7/19/2015 by Hector F.

This is a 230 volt version and yes an Intelliflo will replace it.

?     Asked on 4/9/2015 by

What is the power consumption on the WFE-4? Currently have one that pulling 2KWH of power. Which seems really high to me and not very energy efficient.

A     Answered on 4/10/2015 by Robert M.

The pump should normally be pulling 1.7KWh. The input voltage may be running high. This would cause the KWh to increase. If the amps are higher than nameplate amps but the voltage is acceptable, WITH THE POWER OFF, inspect the motor and the pump for mechanical obstructions that could cause an overload. We recommend contacting Pentair if you are still having issues.

Is this pump available with a choice of a square flange (like the Pentair SuperFlo), in addition to the flange shown on the picture? If so, any advantage to either flange? Any price difference? Also, am I correct thinking that this pump with its 2" ports would allow better water flow than the SuperFlo (with smaller ports), used on a system having all 2" pipes ?

A     Answered on 3/17/2015 by Hector F.

This pump model does have square flange motors and also is set up for 2 inch plumbing. There is no advantage in either square or round flange motors. 2 inch plumbing would allow better flow on higher horse power model pumps.

The pump that is on it now is a Marlow 1.5 J75EC RG what would be the cross over to a pentair whisperflo energy effcient?

A     Answered on 11/7/2014 by Patrick P.

The Energy Efficient Whisperlo replacement for the Marlow 1.5 J75EC RG Argonaut Pump would be the Pentair Whisperflo WFE-26 (011518) Please note that the plumbing ports on the Whisperflo are in a slightly different location than the Marlow Argonaut so you may some minor re-plumbning.

Can you help me find replacement seals for this Pentair Whisperflo pump?

A     Answered on 1/23/2013 by Patrick P.

We have 2 different tune-up kits for the Pentair Whisperflo. The first one is for a standard pools and the second one is for saltwater pools. The saltwater tune-up kit comes with a heavy duty shaft seal and can be used on all Pentair Whisperflo pumps.

Pumps my 1-1/2hp pool pump (Centurion CF11 N1 1A) went out when I fired it up (12 years old) Looking at maybe upgrading to energy efficient pump... considering Pentair or maybe Sta-Rite. Your Pentair WFE-26 (547.99) and WFE-6 (515.99) seem very similar but they are described as "up-rate" (26) and "full-rate" (6). What is difference and do you think these are similar to my current pump. (24700 gal pool; 230/115 pump we are wired for 230)Other or better suggestions? Last year I picked up a used sa

A     Answered on 4/14/2012 by Patrick P.

Based on your pool size you need a Gallon per minute rating (GPM) of 52 GPM's to turn your pool over in an 8 hour time period, I show that your current Challenger pump outputs roughly 60 GPM's and we show that the part # you provided for your current pump is for a 1 HP. The sand filter you have has a GPM rating or 62 GPM's where the large Sta Rite filter has a GPM rating of 110 GPM's. The uprated WFE-26 pump outputs a GPM of 80 and the Full Rate WFE-6 pump has a GPM of 100. With all of this being said I would suggest going with the WFE-26 if you are going to stay with your current set up and swap out to the Sta Rite filter as the current sand filter can only handle 62 GPM's if you do intend on adding water features or see the need for the increased GPM's in the near future then I would go with the WFE-6 and swapping out to the S8M150. Lastly note that the amp draw is less on the WFE-26 so your operational cost would be roughly 20% less then that of the WFE-6. You may view or p

I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?

A     Answered on 2/16/2012 by Patrick P.

Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.

 (5 out of 5 stars)  This one is perfect

from Jacksonville, FL ()

Pros: It is so quiet ...

Cons: None !

I have to thank INYO for the quick response to my order. I was in desperate need of a new pump and their unbeilevable turn around time on my order saved the day. Thank you. Thank you. Thank you!!!!!! I feel fortunate to have found this site. The price was the best I could find. And their service was even better. Kudo's to INYO. You have my respect and my business going forward. This is a really good pump, I'm very happy with it ... it's so much quieter than our last pump. I have to look at the waterfall so I know that the pump is on.

 (5 out of 5 stars)  Only pump we now use

from West Yellowstone,MT ()

Pros: Lasts longer, quieter, uses less energy

Cons: Price, Usually requires minor re-plumbing to fit intake and output

Our hotel pool and hot tubs run 24/7 all year long. We have now replaced all of our pool and hot tub pumps with this Pentair Whisper Flow model because it simply lasts longer than other brands and types we have used in the past that usually required rebuilding every year to prevent ruining the bearings or windings due to leakage. Leaking pool pumps mean shutting down an important amenity at the worst possible times and requires a lot of maintenance time and expense. Our experience with these pumps is that they seem to run forever with less maintenance than any other we have tried. The Whisper flow high efficiency is much quieter and more powerful then comparable pumps so you have to be careful to understand actual HP including the service factor and downsize the HP as needed not to increase flow rates to excessive levels. It basically provides more water flow for less HP and less electric use than most other pumps so you usually need to choose a lower HP rated pump to get the best flow result and reduced energy usage and noise. It is the only pump we will now use for any pool equipment in our hotels.

from Churchvile, PA ()

Pros: Quiet, powerful pump.

Cons: Minor change to previous Jandy install plumbing

Bought to replace failing Jandy Stealth pump and could not be happier. It was easy to install and I am impressed with how quiet it is and overall efficiency. I would highly recommend it to those looking to replace their current pool pump.

 (2 out of 5 stars)  pentair - what a joke

from PA ()

Pros: motor is quiet

Cons: pentair is TERRIBLE

I had a Hayward system and my dealer recommended a Pentair as long as I had to increase my hourse power. Overall the pump is quiet. The problems are with pentair. My husband and I are very handy, I read through all the informaiton that came with the pump. Cable gauge and cable length chart, and installed accordingly. The moter stopped working and overheated. I spoke to pentairs technical department. They couldn't figure it out, it was like dealing with a computer company when they are reading from a script. The name plate on the pump stated 120v. Come to find out, and noone told me this after several calls, the system comes wired from factory at 240v. This is a big issue with cable size and breaker amp panel feed. This was only told to me by a tech company they sent out after several calls. So because I had is hooked up for a 120v, being this is what was on the name plate, they voided the warrenty on the system. What a joke!!! Pentair needs to get there act together. I have reported this to UL as the name plate needs to be labled as they are shipped from factory ready for hookup. I hope pentair recieves a HUGE fine.

This 1.5 Horsepower pump is strong and quiet. It has more power than my last 2.0 HP pump and it is almost silent. I can barely hear it from the swimming pool and it jams water through the system. Great product.
