I have a 30,000 gallon pool with spa and currently have a WhisperFlo Pool w/Spa pump but it is not working. The Model # is WFE-4 and I want to purchase a variable speed pump for the SCE Rebate but am unsure what the correct equivalent variable speed pump would be, any help would be greatly appreciated!

A     Answered on 6/29/2017 by InyoPools Product Specialist Patrick P.

Hi Jessica, The proper variable speed pump replacement for your WFE-4 pump would be this Pentair Intelliflo Variable Speed Pump and it should qualify for your SCE Rebate.

I want a dual speed for this model. How do I order it to be dual speed with a toggle switch?

A     Answered on 6/16/2017 by InyoPools Product Specialist Lennox H.

Hi. The Whisperflo - WFDS-4 is the dual version of this pump. The Switch 2 Speed Toggle - 79129900 is not included with the pump, it sold separately.

A     Answered on 3/16/2017 by InyoPools Product Specialist Lennox H.

Hi, Rick. The Hayward Tristar VS Variable Speed Pump - SP3200VSP or Pentair IntelliFlo Variable Speed - 011018 would be the most suitable replacements.

How do I know if my pump is a We or WFE? I have a Whisperflo 1.5 hp.

A     Answered on 12/23/2016 by InyoPools Product Specialist Stacey M.

Hello Mark, There would normally be a model number on the side with a 7-type there could also be a model number on your housing or where your basket is. There are several different models.

What does GPM stands for in pools

A     Answered on 11/15/2016 by InyoPools Product Specialist Lennox H.

Hi. GPM is acronym for gallon per minute which is a calculation of the pump's flow rate.

I need a timer for this pump:Whisperflow-EE 1 HP- 2 speed WFDS-4 230 V so that I can turn it off and on. also I need a chloride generator that will work for my 11K gallon pool. Thanks iliyassou

A     Answered on 10/4/2016 by InyoPools Product Specialist Scott W.

You could go with the T106R for the timer and the IC20 for your salt system. Otherwise, you could go with the IntelliTouch with the chlorinator and you would be able to control your pump, salt system, lights, whatever other features you have. That is just an option. Let me know if you would like more information on that and I can send you a quote of the details and price.

Can I get this WFE-24 unit with a variable speed motor

A     Answered on 9/13/2016 by InyoPools Product Specialist Scott W.

If you are looking to purchase the entire pump, the WhisperFlo only comes in single speed or dual speed. If you are looking for a replacement motor, that part number would be ECM16SQU. If you currently have a 1HP motor, you will need to upgrade to impeller as well if you upgrade to this variable speed motor.

I cant start the pump what I have to do

A     Answered on 8/24/2016 by InyoPools Product Specialist Alan M.

There can be many reasons your pump has malfunctioned. I would start by making sure the breaker has not been tripped. You may need to contact a local repair technician to repair the pump or possibly the manufacturer to assist on the phone with troubleshooting. The manufacturer's contact number is 1-800-831-7133.

Do you sell the whisper flow without the pump??

A     Answered on 8/9/2016 by InyoPools Product Specialist Alan M.

I am guessing you are asking if we sell the pump front half without the motor attached, and if so, the answer is we unfortunately do not.

?     Asked on 7/29/2016 by Jim Wahl

We just put in a new swimming pool three months ago and have been running a new 1 hp with whisper flow 24 - 7. Our electric bill went from $150 to $450. Is there anyway to make this pump draw less electricity. One of the biggest selling points on this pump is that it is efficient? $300 per month is not efficient. Do you have any suggestions as to how I can lower the electricity bill?

A     Answered on 7/31/2016 by InyoPools Product Specialist Lennox H.

Hi Jim, Running a single speed pump 24-7 is costly, you may want to look into getting a dual or variable speed pump or motor. Its will allow you to operate the pump at different speeds to save on operating cost.

?     Asked on 6/2/2016 by tom

I have a 1H.P. pentare pump, WFE-4 on a 220 breaker.Three wires running to the pump,2 black and a ground.Do I attach only one wire to L1 on the back of the pump or one to L1 and L2 plus grounding of course. My pump runs at 100 GPM, to much for a 24 inch dia. sand filter isn't it or not.I think the filter has a G.m.p. of 48 gallons.Thanks Tom

A     Answered on 6/9/2016 by InyoPools Product Specialist Lennox H.

Hi Tom, To wire the motor you have you will place one of the black wire on L1 and the other on L2 and the Ground. If your filter flow rate is 48 gpm, then yes, your pump is too big.

?     Asked on 5/22/2016 by Heather

Can I put a 2-hp motor in a WFE-4 pump?

A     Answered on 5/22/2016 by InyoPools Product Specialist Patrick P.

Heather, if you decided to go with a 2 HP Whisperflo Motor then you would also need to replace your impeller with a 2 HP Whisperflo Impeller and a Whisperflo Tune Up Kit. You will also want to make sure your filter can handle the increased flow of the pump, normally there will be a label on the side of your filter that gives a max flow rating and you want to make sure the 2 HP pump does not exceed this. Finally on a 2 HP pump you will need at least 2" plumbing and 2.5" would be ideal.

?     Asked on 3/10/2016 by Ron

We currently have the 1HP WFE-4 pump motor. It has been recommended we consider replacing with a variable speed motor to have better efficiency. Does this make any sense and would it be cost effective? We were told it would save approx. $30-$40/ month

A     Answered on 3/11/2016 by InyoPools Product Specialist Lennox H.

Hi Ron, You can switch to the V-Green 1.65 HP Square Flange Variable Speed Motor (ECM16SQU) which will save on operating cost. The savings will vary depending on use, but switching to this motor will save you money. If you do replace your current motor, we also recommend getting the Pentair/Purex Whisperflo Tune Up Kit p/n GOKIT32 or GOKIT32SALT depending on method of sanitizer.

?     Asked on 3/4/2016 by Nick

How long is the warranty if you install it yourself. I have seen where the 1 year warranty is only good if "Professionally" installed.

A     Answered on 3/4/2016 by InyoPools Product Specialist Lennox H.

Hi Nick, The Pentair Whisperflo Pumps comes with a 1 year warranty if installed by a qualified installer and 60 days if not.

How many kilowatts does my single speed1 HP Whisperflow pump use to run?

A     Answered on 2/12/2016 by InyoPools Product Specialist Christian R.

A 1 HP full rated uses somewhere around 1400 to 1650 watts depending on the price of kilowatts in your area.

?     Asked on 10/30/2015 by Brandon

I bought a house with a pool. It came with the WFE-4. The motor has gone out. Can I replace the single speed motor with a variable speed one or do I need an entirely new pump? If so, which motor do you recommend?

A     Answered on 11/2/2015 by InyoPools Product Specialist Joe S.

Hello Brandon, you can covert your single speed motor to the ECM16SQU variable speed motor. Also remember it is wise to change all the orings and seals when you change the motor. That will be part number GOKIT32 or if you have salt you would want to use GOKIT32SALT

?     Asked on 6/16/2015 by jude

what is the difference between the WFE-4 and WFE-24

A     Answered on 6/16/2015 by InyoPools Product Specialist Dennis R.

Jude - The actual or total HP ]THP] of a motor in equal to its stated HP x its Service Factor (SF). Although the stated HP for both WFE-4 and WFE-24 is 1 HP their actual or THP is: WFE-4 = 1 HP x 1.65 [SF] or 1.65 THP; WFE-24 = 1 HP x 1.25 [SF] or 1.25 THP. Bottom line: WFE-24 ihas 0.4 HP less than WFE-4.

We have an above ground, 10-12,000 gal. pool. Need an energy efficient replacement pump. Can we use this one for above ground, and is it available in a 110 power cord plug-in?

A     Answered on 5/31/2015 by InyoPools Product Specialist Patrick P.

Hi Stephen this pump could be used on an above ground pool but would require 2" hard plumbing and I honestly think this pump would be overkill for your pool. This pump does not come with a 110v plugin cord but you could purchase one seperatly or use your current cord. For your pool I would suggest a 1 HP Dual Speed Above Ground Pool Pump which will cost much less to operate than this pump and would be more well suited for your applicaiton. Also the dual speed above ground pool pump comes with a cord.

Is there an on/off switch?

A     Answered on 5/31/2015 by InyoPools Product Specialist Patrick P.

A     Answered on 12/4/2014 by InyoPools Product Specialist Brian M.

Hello  Eddie. We get this question a lot. Full and Up Rated motors were the industries first attempt at making motors more efficient. This was before 2 speed and variable speed arrived.  This is a link to and explanation of How To Understand True Pump Horsepower - Up Rated vs Full Rated.

I am replacing my pump and it's currently got 1.5" piping. Is there a way I can get this pump (with the 2" piping) to work with it?

A     Answered on 6/3/2012 by InyoPools Product Specialist Patrick P.

This pump is only available in 2" ports however If you have 1.5" pipe it is not a problem to go up to the 2" ports on this pump and this can be accomplished by the purchase of two standard pipe fittings which can be purchased at your local hardware store. The problem would occur if you had 2" pipe reducing down to 1.5" ports as this causes a bottleneck, however going from 1.5" pipe up to 2" ports does not cause any issues.

?     Asked on 2/16/2012 by Guest

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 InyoPools Product Specialist 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.
