The only way that they are all alike is that they all pump, circulate, and help filtrate the pool water.  For the sake of this discussion, I will now let you in on the types of inground pool pumps available and intentionally avoid above ground pool pumps as they should not be utilized on inground pools.

PUMP TYPE:  Single Speed

Single speed pumps have been the staple on inground pool installations for decades now.  When it is running, it is at a single constant speed.  Due to this they are the most expensive pool pumps to operate.  While there have been many innovations on the hydraulics over the years that make them much more energy efficient than the old days, they are still very common and the least expensive type of pumps to purchase.

PUMP TYPE: Dual Speed

A dual speed pump is a close cousin on a single speed pump.   The motors are very similar except the dual speed pump does have a low speed option that is more energy efficient.  Please be aware that there are times when you want the pump on high speed, such as when leaves are prevalent so that the pool will ‘skim’ property, anytime you want to heat the pool, and of course when you are using your manual vac system so that you have lots of suction while cleaning the pool.  A dual speed pump is considerably more expensive to purchase than a single speed pump, but typically saves you 50% or more on electricity.

PUMP TYPE: Variable Speed

These pumps are made special by the use of permanent magnet motors.  The pool owner can program the motor down to as little as 1/10 of a horse power.  Some of our clients with them actually run their pool pumps 18-24 hours a day.  Since slower water movement creates less drag, the circulation system becomes incredibly more efficient. Other reports from our clients are that they vibrate less, are quieter while running, the motors last longer and some folks just like the advanced diagnostics and programmability.  A lot of studies have been published that claim that they are almost 90% more energy efficient than single speed pumps.

Which pumps do American Pools install?

Well the answer is all of them.  If price is a big consideration then a single speed pump is best.  If you are skilled in programming things, if you like high tech stuff and don’t mind paying the up charge, a variable speed pump is just for you!

    Thanks for sharing this with all of us.
    I have owned 3 pools. 2 had single speed pumps, 1 had a variable speed pump.
    I definitely recommend to everyone to go variable speed. It uses much less electricity.

      Thanks for joining us and sharing your opinion. I recommend the variable speed pumps to ‘techies’ that like to program things.

  2. Terry Zoch says:

    Hi Wayne! Just wanted to say another big thanks for the job your team did on our new Rio Bravo pool last August.

    Your team was great to work with from start to finish!!

    • wayne says:

      Hi Terry! Nice to hear back from you and glad you love the American Fiberglass Pool. Thanks for the kind words.

  3. Talia V. says:

    We have been researching pools all year and have decided that a fiber glass pool will be the best one to own.

    You can call us @ 713-******* to set up a time to give an estimate.

    We live in The Woodlands

    • wayne says:

      Hi Talia. All the permit paperwork was sent in early this week. We are looking forward to building your family’s beautiful new American Fiberglass Pool model Pecos and spa.

  4. Jay Gardner says:

    Thanks for the tips on pool pumps.
    We are wanting a new pool built this winter & it must be fiberglass. Please call us for an estimate to be given. 361-***-****.

    • wayne says:

      Hi Jay. Your beautiful, affordable, VERY LOW maintenance American Fiberglass Pool model Nueces was completed in the factory yesterday. We will get with you after Thanksgiving to stake out the pool and get started.

  5. O.R.Powers says:

    I did not know there are different kinds of pool pumps available. What kind of cost should be expected over a month with a single speed pump that has a time clock to turn it on and off?

    • wayne says:

      Thank you for your question. A typical American Fiberglass Pool installed with a single speed pump and a time clock set for 7 hours a day should run between $25-$35 a month. This is dependent on the size of the pump required to properly filtrate your pool.

  6. Adrian Grarrett says:

    Your articles are always interesting. I have been following them for almost a year and now are ready to move forward with a new pool.
    You can reach me at 512-***-****.

    • wayne says:

      Thanks for the kind thoughts! We will be starting the construction of your American Fiberglass Pool model Brazos in 2-3 weeks if the weather cooperates. Looks like you will have the ultimate Christmas gift for the family, a beautiful, affordable, VERY LOW maintenance American Fiberglass Pool!

  7. M.Brookside says:

    We have owned a fiberglass pool in Florida for almost 25 years. We have moved to the Houston area and fiberglass is the only way to go on another pool. We never had any issues with the pool whatsoever while all our friends were struggling with their concrete pool maintainence and re-plasters. Our new home will be in the Pearland area and would appreciate your call and estimate.



    • wayne says:

      Always like to hear from long time fiberglass pool owners. The building permit for your new American Fiberglass Pool model LLano will be submitted next week. After that, expect lots of things to happen real quick with your pool purchase.

  8. Leah Brill says:

    We watched you build a pool for a neighbor last month and were impressed with the speed you built it. We have watched other neighbors suffer thru months of gunite pool construction but your crew finished the pool in three weeks.
    We were as well impressed with how the yard and driveway were kept clean while the pool was being built.
    Kudos to your crew for all the extra effort!

    We have watched for years now and would like to build our own pool. It will be a fiberglass pool of course.
    Please contact us at 281*******

    • wayne says:

      Hi Leah. We look forward to starting your pool as you have requested after you return from your Christmas holiday!

  9. Hank Rosin says:

    We had a Hayward Ecostar variable speed pump installed with the pool you built us last Sept.
    I must say that we have been blown away by the energy efficiency. By our calculation we are using only $14 a month to circulate our pool!!
    A variable speed pump is the only way to go boys and girls…..

  10. Rob F. says:

    We want to construct a fiberglass pool this winter. We own a contracting company & wish to do some of the work ourselves. In particular the electrical & concrete work.

    Please call asap at 281-*******.

    Thank you

    • wayne says:

      Hey Rob. We are set to start your American Fiberglass Pool model Trinity by Christmas. Don’t do any more rain dances please!

  11. Kurt. says:

    I have been a pool service company owner for 12 years. I think that single or dual speed pumps are adequate in most cases.
    Varible speed pumps are just too complicated to operate correctly for most pool owners.

  12. Ted Juerguns says:

    Enjoyed your read as usual. Please keep up the interesting work!

  13. Harry Schumer says:

    I did not know there are different kinds of pool pumps. Thanks for the education.

  14. Angelica says:

    We will have to replace our 11 year old single speed pump soon.
    After reading this blog we will install a variable speed one when the time comes.
    Thank you for alerting us to the differences.

  15. Opie says:

    Good read!

    What would you say the % of each pump that are actually installed out there??


  16. Andrew C. says:

    Just wanted to say hey and thanks again for the super job your guys did while installing our Guadalupe model pool. Your guys were pleasant, cleaned up every day, and showed up at the same time every day[7:00] to work.
    It was easy for us to plan our daily activities knowing when your crew would be here.
