Why do you think turnover matters? It does not matter for any pool water quality.

Renante,

I have no heater and at 1200 rpm, my filter pressure is about 1 lb. on a 30 lb. gauge. (Note.. I don't know my GPM, and could not care less.. )

You are just making things harder on yourself.

Filter pressure shows how hard it is to push water through your filter, not how well your pump is running.

The real key is to just feel the pool returns.. Do you have plenty of water returning to your pool? I suspect that you do.

The whole point of having a VS pump is to run as slow as you can and still get the job done..

What specific reason are you running at 58 GPM?? Sounds like you might be worried about "turnovers" ???

Thanks,

Jim R.

Hi Jim,
Thanks for getting back to me. Yes, I have three output jets, and they’re returning water very well—much better than the old 15-year-old DE filter. I'm currently running my variable speed pump at 50% (around 1,700 RPM), which is the same setting I used before switching to the new cartridge filter. I’m considering lowering it further to target around 28 GPM, since I’m running the pump 12 hours a day to achieve one full turnover daily for my 20,000-gallon pool.

And hey—I probably am making it harder on myself, but what’s a project without a little overthinking, right?

Maybe try some contact cleaner.

Many different brands like WD-40.

Note: Not regular WD-40.

Stabilant 22 Is a much better contact enhancer..

If you count backwards from 10, the gauge actually shows 5 psi, which is pretty close to the expected 6 psi.

How high is the pressure gauge above the pool water surface?

Thanks all

2 PSI at 50% and 4 PSI at 70% says your PSI gauge is responding as expected.

As was said, the lower the PSI the better.

Do you have a 3 hp Intelliflo3 or a 1.5 hp Intelliflo3?

A 3 hp pump would be at about 17 psi.

A 1.5 HP pump would be about 6.5 psi.

Hi James sir,
I do have 1.5 HP Intelliflo3. I asked the pool techs after they installed the filter and redo the piping and he said it's normal and the lower the better. It's just weird to me that only 2 PSI registers at 50% speed with 42GPM. Like you mentioned, I also expect around 5 to 10 PSI. Thanks sir for the response.

A couple weeks ago I started trying to repair the latch on the gate around the pool equipment…

Then it kinda snowballed into a fence renovation, plumbing renovation, downspout extension, backwash plumbing line, and landscaping.



I got big stones laid down in front of the pad so I can not have to mow right against the pad anymore. I got a downspout extension ran out under the stone, including a backwash port I can tie into so backwash water doesn’t flood the pad anymore), new fence post footings installed, new conduit for sprinkler controller wires, and I got almost all of the plumbing done (still waiting on a couple MPV fittings) and then notice this little oddity on the return line right as it goes down into the pad concrete. If you zoom a bit you can see it. Looks like someone inserted some kind of union? on the -inside- of the 1.5” pipe right below the bigger union. I’ve already decided I’m gonna fix that cause it’s easier now that there’s no fence in the way. Ugh.

Sounds like your fill water pH and TA is similar to mine, which makes sense given our wells are probably pulling from the same aquifer.

For the first year of my pool, I had high TA and the pH would rise. I'd let it get up to 8.0 and then add Muriatic Acid to drop it back down to the low 7s (use the aforementioned PoolMath app to tell you how much to add.) I had to do that a few times, but then after a while of doing that the TA came down and now it pretty much balances itself unless I get heavy rains that dilute my TA, or have to add a lot of fill water that raises it back up.

What is the power usage at those numbers?

How high is the pressure gauge above the pool water surface?

What is your PSI at 100%?

Click to expand...

Hi sir,
Yes, no heater. I will check later the PSI if I run the pump at 100% speed. I know that the PSI is 2 PSI at 50% speed with about 42 GPM. Thanks for the response.

Do you have a 3 hp Intelliflo3 or a 1.5 hp Intelliflo3?

A 3 hp pump would be at about 17 psi.

A 1.5 HP pump would be about 6.5 psi.

You can use a 2 1/2" coupler on the outside socket of the diverter valve and existing check valve. Refer to the connection on the left side of the valve below.

Also how does this happen when I have maintained the chemicals?

Just because I've seen the current-sensing relay mentioned in here a couple of times, here is a link to more info:
Current Sensing Relay for SWG with Variable Speed pump
I just installed one myself recently when I replaced my dying motor with a VS.

Pictures help.

The stains didn't get there overnight. Expecting them to be gone overnight is not realistic.

So, if the stains lightened with the tablets, that indicates they are iron. An ascorbic Acid treatment would be my next step


I have no idea what "A+ stain remover" is nor do I have any idea what the Chlorox stain remover is.

Stay away from "Magic bullets". Do the ascorbic acid treatment and report your results

Can you confirm this is the way? Ascorbic Acid Treatment - Further Reading

Get the Menards. You'll need 66% less to get to the same sanitizer level as the weaker bleach. Fewer jugs to buy, less in the pool each time.

A gallon of 12% for 4.99 gives you much more chlorine ppm then 81 ounces of 7.5% bleach for $4.52.

So does a gallon of 10% pool shock for $5.67 versus 81 oz of 7.5%.

You need to look at the amount of chlorine you are getting for the price.

A gallon is 128 oz with more chlorine then the 81 oz with less chlorine.

sequestrant works in your pool by keeping solids in solution. The contaminants are still there in your pool, you just can't see them.

So if what you are seeing is inorganic, you need to add more sequestrant to make them return to solution but even better may be to capture and remove them with polyfill

Thank you, I suppose no downside to trying polyfill. It could be falling from the sky as we have a terrible pollen season here. No staining on the floor so I imagine the solids are still in solution. Appreciate the help.
