High CYA. How much to drain?

jb,

I'd want to get some Liquid Chlorine in the water first, but it will burn off pretty quickly as your CYA should be pretty low... I'd add enough CYA to get you up to 30 ppm or so.

It will take a couple of days for the CYA to start showing up in your tests.

Then start getting your pH in the 7's and your CH up if too low..

The most important part, in my mind, is to keep your FC at the target range for your CYA, no matter what the CYA is right now. And as you slowly add any new CYA..

FC/CYA Levels

Thanks

I drained almost all last night Maybe 6inches left in the deepest spot. Cya not showing up so assuming I accomplished lowering it. Pool math says 3.5 pounds but thinking I’ll start at 3pounds cya then remeasure in a couple days. Just added about a quart of acid to get ph in the 7s . I was shocked to see Ch was 175. San Antonio has very hard water. Pool math says 41 pounds of calcium chloride. Does this sound correct? Should I retest this again after CYA additions? TA very high at 200 as well. Hoping acid addition brings that down some. Any advice is appreciated!

Chlorine Generator Requires Pump to Run at 2500+ RPM

Welcome to TFP.



Yup, that can do it.

The Intellichor Installation Manual says - For best flow sensing, provide at least 12"-18" of straight pipe in front of the cell inlet.

That check valve is not needed with a SWG. It is leftover from when tablet chlorinators were used.

If I were you I would remove the check valve cover, remove the spring and flapper, and replace the cover. See what difference it makes.

Your SWG should get flow on at around 1800 - 2000 RPM.
I was thinking about giving this a try as well. Why does the SWG not require a check valve to prevent water from flowing back into the heater? I understand the cell won’t generate chlorine at low/no flow conditions, but the water sitting in the cell when pump stops could flow back into the heater? Is it just not enough chlorine present to make a big impact in terms of corrosion?

Jandy JXiQ heater not starting

You may have air in the gas line that needs to be purged.

You may have to go through ignition cycles and lockouts several times, as a bit of air is purged with each cycle until the heater gets gas.


If the ignition is unsuccessful or the flame fails during normal operation, the ignition control shuts off the gasvalve. The heater will then go through a post-purge process and attempt to establish stable combustion two additional times. If ignition is unsuccessful after three attempts, the system will lock out.

The Installation Manual says to reset the heater after a lock out:
  • Turn OFF the power at the breaker for the power cycle, then turn it back ON.
  • Access either the Pool or Spa mode.
A member reported that it did not work. Holding the Pool Menu and Spa, which brings up a menu to reset the latch fault, did.

Manually wiring GVA-24 Actuator Valve

With an aux relay on the prologic, it's not automatic and defeats the purpose of having an auto actuating valve imo.
There is no way to do this simple thing on a prologic. Which sucks. But is what it is.
I wanted it so when the spa pump is on, the valve is set to the correct direction. And same for when its off. Automatically.

When it comes to my plumbing. Thats a whole other story. Its much more complicated than this valve setup. And i just don't have the time to lay it all out.
Simply put - the spa and pool have a shared heater but with separate pumps/filters.
The valve in question changes where the water is returned to the pool/spa.
In the direction for the pool it returns to the pool through a 8 zone caretaker99.
If the spa pump is on while the valve is in the pool direction, it sucks all water from the spa and into the pool. Emptying the spa, and eventually running the pump/filter dry.
If pool pump is on while in the spa direction it just overflows from spa into the pool. Which can cause a huge issue if my heater is set to auto. It can empty my 250g LP tank in a night.

I'm also working on an auto top off for the pool using a float switch im putting in the pools skimmer area.

Jacuzzi jscs40 swg leaks from connection

Jacuzzi does not manufacture any of its pool equipment. They put their brand on other manufacturers' white label models.

The JSCS40 looks like the Circupool SJ model SWG.


O-rings are a commodity product and are generally available. I suggest you measure the O-ring size and read...

I checked and the o-ring I tried to replace it was for that model swg. It still leaks. Both the original and new o-rings are in good condition with no nicks, cracks or flat spots. I used pool lube when I installed. I’m at a loss as to what to do now.

What did you do to your pool today?

Drained about 3" of water from the pool today. A series of rain storms had raised the water level to the top of the skimmer. The chemical level have all decreased a little bit. Nothing real urgent needs to be taken care of.

Right now I'm having persistently high FC levels. I keep lowering the output yet the FC is still rising. I lowered the output from 40 to 20 a little over a week ago and now I lowered it to 10% since FC went from 11 to 12.5 ppm in the last week. I'd like to see it at around 6 ppm. I may shut down the SWG for a few days.

SWG & Salt level

31.9 is the voltage, and 0.00 is the amps when the cell is in a resting state and not generating chlorine.

Report all diagnostic readings when you..
  • Move the switch from auto to off and check all of the readings.
  • Move the switch back to auto and recheck the readings.
  • Move the switch to off for a minute and then back to auto and recheck the readings.
Moving the switch from AUTO to OFF and back triggers the cell to generate, and by doing it twice, it checks the diagnostics on both cell polarities.

Scroll up, I did that. I'll do in the order you suggested again though. Thanks.

SWG & Salt level

While generating, i'm showing 4200, 76deg, 31.9, 0.00, -0.
So that doesn't look good per the manual? I'm not showing a salt calibration or amps..

Pool Chemistry, stainless steel corrosion and prevention, long term study.

I have nothing to add that is of benefit to this conversation but I would like to say these discussions are why I follow TFP. Guys like @JoyfulNoise, @JamesW and @mas985 (among others) say it works, I know they've put some thought into it and can back it up with hard numbers.

I'm just here to watch and learn.

Is this pump fully primed?

First of all, thanks very much to the community, I've learned a lot. There's so much information in the forums, and thanks to the search functions I've never had to ask a question. Until now. :)

I'm helping a friend whose pump seems to be operating sub optimally. I have replaced the cover o-ring, removed and lubed the drain plugs, and while it's better, it still doesn't look fully primed. Or rather, it doesn't look like mine as the water doesn't splash to the top.

Is this primed or do I still need to be looking for where the air is getting in?

Thanks!

What did you do to your pool today?

If so inclined, you can find plans and build your own for the cost of the lumber which will cost substantially less and provide more satisfaction.

Once I get home I’ll take a pic of mine.
As promised and needs a bit of work. I keep it tarped over the winter.

Jandy JXiQ heater not starting

Hi Folks,
We’ve only had our heater for less than a year and recently had to turn off our main gas line for a day.

Ever since the heater is throwing an error stating:

Fault Ignition Control Lockout. Service Required.


I have tried many things including turning off the breaker for several minibus it always starts up that way.

Any recommendations on how to troubleshoot?

Unfortunately, our pool guy cannot come check it out for two weeks and our kids really want to get in the pool.

Thanks
