Documentation note. REplaced my water pressure gauge Today. I measure an increase of 3 psi if I route all my water flow through my two Intex SWG.

Have you considered running them in parallel? It should reduce the backpressure.
In essence they are in parallel. I have them plumbed in way I can divert certain amount of water to the SWG "circuit" and I can bypass the two SWG for service reason or take it in during a hurricane warning...which I have done once last year.
I did the measurement as note to anyone out there that might to try this setup.

I was referring to running the SWG's themselves in parallel, instead of being linked in series.
you are right some one else out there might want to consider plumbing them in parallel. Luckily I don't have the back pressure issue since I divert maybe 30% to 50% of the water flow into the SWG circuit. The previous owner had a solar water heater which is no longer there and I am using that existing plumbing for the two SWG
Documentation note. The two intex swg has been working perfectly for the past 2 years. Right now I have pool pump, swg running 4 hours a day. It has paid for itself after year one
Good to hear. My pair ran great all last season, I expect the same this season. See the link in my signature.
Paul, I’m an EE and I have to tell you that’s impressive, you’re definitely thinking WAY outside the box.

Yes, I'm an EE too (in the PC industry) turned web architect/programmer. Redundancy with low cost interchangeable parts is the name of game in my industry. I also liked domct203 plush setup. I shamefully have same concrete block shelves. Also note this thread about the new intex: https://www.troublefreepool.com/threads/163707-New-and-possibly-NOT-improved-Intex-SWG
i am running my setup 5 hours a day in hot sunny florida. I need an extra hour of run time for additional chlorine but I am trying to avoid by cleaning the plates. 2nd time in two years. I have yet to use any acid for cleanup. 1/2 credit card did the trick to dislodge calcium build up. Hopefully then mechanical scraping is less harsh than using vinegar.
The reason I am trying to avoid the extra run time is because I have single speed pool pump. I calculated it cost me $0.25/ hour to run my pump. The economics says its cheaper to buy chlorine than run the pool pump/swg combo
Note $2.4 per pound to buy vs $5 per pound to make using swg/inefficient pool pump combo
Calculation
from Pinch Penney pool store
$2.4 per pound of chlorine (from 2.5 gal of 10% chlorine at $5 per yellow jug)
from two intex/pool pump/electricity
$5 per pound of chlorine (from 1.2 lb per 24 hours or 24 x $0.25 electricity = $6
or $5 per pound to make my chlorine via swg/pool pump)

Documentation note: Low salt warning one of my swg. My ph was off balance for a few days and I was surprised by the amount of calcium build. Soaked both units in vinegar.
Documentation Note (been posting across time for my own record keeping): I am on two intex swg system for four years and going on five. I did not expect this setup would last this long and had been eyeballing a Circupool sj-40 (seems to be $200 higher from the last time I looked).... Via amazon or walmart there is no means of ordering a replacment intex swg at reasonable cost. Don't know if its due the corona virus, trade war, shortages of parts etc....
However, the setup going strong. One plastic housing holding the plates together is beginning to deteriorate.. .I have cables ties on them. I just did vinegar cleaning of the plates.
See picture below for condition of the electrode assembly..... cable ties on red area

It’s interesting u should post- your original post on this thread is what led me to the setup i have now - 2 intex swg’s. I have 2 returns so i have one on each return for my 33k gal pool. One of mine is on its 3rd season ( i used it on my previous smaller pool) the other is on its 2nd season. I was able to procure my units at a discount cost off season. I’m sure when this “pool fever”runs its course costs will come back down & availability will come back.
I went looking around on the intex website the other & noticed they have quite a few replacement parts so that may be an avenue for u. I intend to keep my setup as long as possible.
It has been monetarily worth the minor work arounds.
Great luck to u with your set up!

Nice feedback that someone is making use of this info. thanks. I think you are right, the pandemic is increasing sales of above ground pools (did some googling)... so it is matter of time waiting things out pricing to go back down. I have spare refurb unit in attic (that I bought off ebay at a steal $40) that should let me limp along until next year at if something fails.
Hoping to Buy an Aboveground Pool to Salvage Summer? It May Be Too Late
Pandemic boosts pool industry sales

Doc notes:
Ordered a replacement electrode from Intex Corp. I have been running two units for 4 years. I swapped out one unit with my backup. I noticed the replacement unit produced a significant amout of bubbles compared to the older unit. So I have new electrodes on order for $73. They had been out stock for several months. Decided to grab one to be on safe side. Also concerned about future price hikes.
See SWG Prices
Running on one unit for 6 hours maintains my chlorine level with newer unit in hot florida summer. Prevous 4 years I have been sloppy in maintaining my water chemistry so must have soaked the unit over dozen and left the CYA level too low. I am estimating based on my experience my setup has 3 years of life...maybe more if I took better care.

This is super cool. You basically have the capacity of a T15 cell with replacement electrodes in the $60 range. I like it.
Quick status update. Replaced the Titanium Electrode of the 2nd unit In June 2021 (wanted to boost chlorine for the summer... was getting weak). 2nd unit died in July (but found found out that it it was the GCFI plug... put regular plug from home depot since my outlet is already GCFI protected using Leviton 15 Amp 125-Volt Double Pole 3-Wire Grounding Plug, Black-R50-3W101-00E - The Home Depot I think these GCFI plug are common failure)
Today Ordered another Titanium Electrode as backup for $74.27 They are back in stock. Concerned about future price increases and have confidence these intex will last long enough to use the backup Electrode before I have to dump the units.I am guessing I will replacing electrodes every 3 years.
Suprisingly Year 5 on my intex so far.
Final note..... Noticed the home depot feedback comments had some one commenting how they replaced GCFI with above plug.. they fit perfectly.... Their picture below:
