Long story short - I live in Fort Myers- storm surge submerged and fried my Superflo VST - should I replace it with the same or consider upgrading to the Whisperquiet ?
Would there be any advantages other than moving more water at a slower speed?
Thanks,

Jon,

You might just have to take whatever you can find. :(

As you say, the larger the pump the slower you can run it and still move a lot of water. This makes it much quieter to run.

Thanks,

have them both located and plan to buy tomorrow- I know the Superflo VST will just drop in - not sure about the whisperquiet.
I am thinking that waterfall and bubblers will work better with increased flow.
It shouldn’t affect the SWG with additional flow should it?

jon,

More flow will not hurt the salt cell at all..

Thanks Jim,
So, it probably will be just a little change in the piping. The builder didn’t install any unions in each of the pump anyway - so I will install them with either pump.
Ther should be a need to remove and clean the inside of the SWG as long it works correct?
 
Jon,

I have never seen a SWCG that was not mounted with unions. They need to have unions so that you can visually look at them. I do that every six months as I have a pretty good feel about the amount of buildup that I get.

I would never install at $1,000 or $2,000 dollar pump without pump unions. You can't buy pump unions at Home Depot. They screw right into the threaded inputs and outputs on the pump.

They look like this.. https://www.amazon.com/PACK-Hi-Temp...hvlocphy=&hvtargid=pla-4584138857632048&psc=1

I think the SuperFlo comes with pump unions. If you buy them, make sure you get the size your pump needs.. Either 1.5" or 2".

Thanks,

No reason to move up to the Intelliflo3 VSF huh?

Jon,

I don't think that the SuperFlo has the same plumbing spacing that the WhisperFlo has.

I am a big fan of the 'bigger the pump, the better' theory. That said, there is no overwhelming reason to move up to a bigger pump unless you are unhappy with the SuperFlo VS. If you are unhappy, then it would make more sense to move up.

I have three IntelliFlo VS pumps. If I had to replace one of them today, I'd probably go with the IntelliFlo3.

Thanks,

Jim R.

Jon,

Well, it turned out I lied... :hammer:

I just saw where they have a 1.5 HP version of the IntelliFlo3. The 1.5 HP version can run off of 120 or 240 VAC.

The ones have seen online are all the 3 HP versions P/N 011075 without the relay card and P/N 011076 with the relay card.

Thanks,

Ok,
I found and bought a Pentair intelliflo VSF. It has 1.88 HHP and 3.95 THP.
My drowned pump was a Superflo VST 1.09 HHP and 2.2 THP.
It was wired 230V so the electric service will run the new pump.
I did touch base with my pool builder ( pool is only 3 months old) and he told me to be careful with the larger pump - that I could damage the plumbing.
So, my thought are to increase the diameter of return eyelets (from 1/2” to 3/4”) so I can increase flow rates.
It’s my understanding the the new pump can be set with RPM or GPM.
For a 12,500 gallon pool - what would be a good flow rate without stressing the system with back pressure?
Any additional precautions or recommendations - greatly appreciated!

Jon,

What a total load of Bull Feathers!!! :mrgreen:

The pump is not going to damage anything, it just cannot build up that kind of pressure.

Besides, you buy a VS pump to be able to run it as slow as possible and still get the job done.

You have a SWCG, so your lowest speed should be whatever RPM turns on your flow switch plus 100 RPM just to be sure. There is no reason to run faster unless the situation calls for it.. Like you want to run a waterfall or ???

I never recommend running in the GPM mode, it just causes people to go crazy..

I run at 1200 RPM most of the time. Since you have a heater, I suspect that you will need to run at 1500 or so. That said, my pump is over 8 years old and the newer ones can move more water at a low speed.

I have a large cartridge filter and at 1200 RPM my filter pressure is about 1 lb.

Thanks,

Jim R.

😂😂😂I thought the same thing as schedule 40 PVC is rated to 600 psi I believe.
And yes - I have a waterfall and 2 bubblers that I will be running.
So Jim,
The the pressure gauge on the filter is giving the back pressure info on the system correct?
Jon
 
Jon,

Yes, the filter pressure gauge is reading how much effort it takes to push the water through the filter and back to the pool. The dirtier the filter and the more restrictions in the plumbing, the higher the pressure will be.

This is one reason that I like large cartridge filters. Dirt simple plumbing and less back pressure.

Kind of like putting your finger over the end of a hose. When you do, the pressure goes up, but the flow goes down.

Thanks,

Jim R.
