How To Make a Pool Pump Quieter!

From www.swimmingpo... this video talks about how to make a pool pump run quieter. When single speed pumps were the only pump options on the market service technicians for pools used to install isolation mats under the pumps which are high density rubber mats and these help to limit pump vibrations through the base. In addition to this a very problematic pool might have rubber couplings or sections of flex PVC installed in the equipment room to try to help isolate the vibrations from the walls and floors where they transmit further to the rest of the living area.
Modernly a variable speed pool pump is the solution for a pump that is too noisy. At lower speeds they are so quiet you can not tell if it is running or not even while standing right next to it. Only at highest speed operation would it be loud like a single speed pump. What most pool owners do not realize is that the pipe size you have (very commonly it will be either 1.5" or 2") through your equipment set will determine the maximum efficiency of your hydraulic system. Laminar flow is water which moves smoothly and without excessive energy losses. When you move water too fast you lose laminar flow and the rate of efficiency loss to friction and turbulence of the water increases logarithmically. Most modern pool pumps will attempt to deliver 80, 100, 120 gallons per minute or more at maximum speed (or single speed) so what is the limit of laminar flow for 1.5" and 2" pipe? Less than you think:
1.5" pipe = 38 GPM
2" pipe = 65 GPM
Everything beyond these numbers that you operate your system will substantially increase the efficiency losses of your pool, but will also account for all that noise that your pool pump is making. Instead, design a 24 hour variable speed pump schedule which remains within the limits of laminar flow at all times - and reduce the noise your pump makes dramatically!

So many old timers kept telling me not to bother with a variable speed pump. Then I watched your videos on testing variable pumps and I decided to buy one. It's been amazing, it's quiet and efficient. I also love the programable schedule features. I found your information useful. Thank you.

Great video as always! Got our pool two years ago and appreciate the time you put in to helping us pool owners.

hello slightly off topic, but wondering what your recommendation would be filter wise. Lots of trees around pool, oak and crepe myrtle. In Texas so constant temperature changes and rainstorms. Pool is consistently algae all over the sides. Pool is also well fed with highish lvl of alkaline in the water. Also very "hard" water. Current filter system is a sand filter. Even when freshly new sand still same issues. Wondering if DE filter would work best for this situation. Just watched ur 4yr vid on the different filters. Not sure if this situation needs a filter that gets the smaller particles.

My pump is only 500w - I'm guessing that its not worth changing it - I run it for 16 hrs a day (It does a splendid job)

The Intex 2500 gallons per hour cartridge filter pump is very quiet

[@HeritageWealthPlanning]

If I can change my RPM does that mean I have a variable speed pump?

[@Swimmingpoolsteve]

that is correct. If you have only low and high speed this is a dual speed pump. If you have control like a dimmer toggle on a light then this is a variable speed pump. Usually a digital interface with RPM, time etc.

@@Swimmingpoolsteve still pretty loud though

[@HeritageWealthPlanning]

Of course my first pool so not sure what to compare it too

[@mstrpth287]

So your solution to make my perfectly running pump quieter is to buy another pump? Maybe you should re-title your video...

[@Swimmingpoolsteve]

Well, literally the first thing I said in the video is (two examples) of how you traditionally solve noise and vibration problems with pool pump. Then I offered a new solution to buy a VS pump.

[@HeritageWealthPlanning]

He literally told us how to do it

[@mstrpth287]

The first 2 ides he literally says, they don't apply anymore. I agree that a variable speed pump is the way to go. My point is that the title is very misleading. And yes, I do own a pool. 20x40 salt with polymer walls surrounded by 22 yards of concrete. Did it all myself and was talked out of the v.s. pump. I regret that decision.

[@Swimmingpoolsteve]

Putting a rubber mat under a variable speed pump still helps to reduce vibration noise. That did not stop working. Same with isolating the pipes with flexible sections to limit pipe vibrations. I am sorry you were talked out of getting a VS pump. That sucks to hear and is surprisingly very common still. I do my best to educate people as to just how much they save with these videos. @@mstrpth287
