CircuPool® Universal25 Saltwater Chlorinator - Complete System with 25k-Gallon Max Titanium Cell & 4 Year Warranty

I can recommend this to be used as an almost dropin replacement for Aqua Rite with T Cell 15, which is what I did. It took me about 2 hours to remove the old system and get the Circupool installed and running. It is working fine but December is the wrong time of year to really give it a good test as the pool water is not hot. Why I chose Circupool: Not pleased with the reliability of the Aqua Rite (more later) when its cell failed I looked at alternatives. The Circupool has several attractive features: 1) claimed easy replacement of Aqua Rite; 2) significantly lower purchase cost; 3) 4-year warranty (although it phases out instead of being true full 4 years); and 4) Circupool being OK with owner installation, including warranty service. Good to know if considering as an Aqua Rite replacement: The Circupool cell does indeed just drop in. I unscrewed the fittings from the Aqua Rite T Cell, pulled it out, and was able to directly put in the new cell using the same fittings...no replumbing at all required. A plus is I was able to use my existing flow switch - the electrical connector on its wire plugged into the Circupool control box and it was recognized. So no replumbing required to swap flow switches! On the negative side the Circupool control box has a different size than the Aqua Rite, and a different location on the bottom of the box for the power cord. So I did have to drill new mounting holes and rework electrical conduit, which is why the replacement took 2 hours instead of 30 minutes. Addressing these differences would be a nice improvement to this product. I won't be able to know about the hot weather operation of the Circupool, nor its reliability, for a while. If it does fail and requires a warranty replacement, the plus which Circupool offers over Aqua Rite is I expect to be able to do it myself, as compared to Aqua Rite which required an authorized service company to provide the warranty service while not paying for that service. I plan to update my review over time as I have experience with the Circupool. History of my Aqua Rite lack of reliability, for anyone considering Aqua Rite (my pool is about 20K gallons, located in south Texas): Purchased new in 2012. Since then the cell has failed 5 times. 3 of those were under warranty, once I purchased a new cell. The most recent failure was the same as what happened once before -- although the cell was still generating chlorine the salt sensor (built into the cell) was resulting in salt level readings much lower than what was in the water, resulting in chlorine generation being automatically shut down due to (inaccurate) low salt levels. In addition to the cell failures the main board in the control unit was replaced once under warranty, and was in fact ready to be replaced again because the little push button switch had worn out and would no longer function. So far I am highly pleased with the Circupool system. I hope it is reliable.

I bought the CircuPool 55K gallon chlorinator in May 2024. It was relatively easy to install, I did it myself in a few hours. It's November 2024 and I noticed my pool had some yellow algae in it. I checked the chlorinator and it had turned off stating that the cells needed maintainance. I disconnected the chlorinator using a large plier like oil filter wrench, took 2 minutes. Then I found the old cleaning cap from my old sucky pentair chlorinator that this replaced, found the pentair cap fit perfectly. So I propped up the CircuPool chlorinator and filled it with a 1-4 mix of muriatic acid and let it sit. It didn't look that dirty, but I did notice some fizzing. I gave it 15 minutes until the fizzing stopped, poured the used muriatic acid down the toilet. Then flushed the CircuPool unit with water. Reconnected everything, and it was producing chlorine again. So for my 30K gallon pool, looks like I have to clean the chlorinator about every 6 months. That's reasonable, having to clean was expected. I like that I went oversized on the chlorinator, I run it at 20-30% power and you can smell the excess chlorine being produced in the water. I live in Florida and its hot, lots of sun to burn up the chlorine, lots of rain to dilute the water, and this thing has really made my life easier and I don't get any yellow algae when the chlorinator and my pump is working proper. All I generally do is add Muriatic acid every couple weeks, about 1/3 gallon, and the pool stays nice and clean and sanitary with the right PH. I do have Vingli pool cleaner as well, inexpensive and it does a good job at sucking up debris on the bottom. One feature that I like about the chlorinator is the FlowSwitch. If the water is not circulating, then the chlorinator shuts off. This is especially helpful because I get a lot of power outages that trigger my pentair pump to shut off. If power comes back on and without that flow switch, the chlorinator would run without any water pump circulation which I think shortens the chlorinator life. I really wish my pentair pump had a battery backup or something, but otherwise its been a very reliable pump, going on 8 years now. One other thing I like about this chlorinator is that it requires much less salt than my old Pentair model. I actually had to drain 1/3 of the pool water out when I first installed it as the pump read that the salt levels were too high. Added back fresh water, things have been great since. No one paid me for this review, I've burned plenty of vendors where necessary. I spend a little time writing reviews as I find they really help me when choosing products. I always state the product name in the review, and if a car part I always state the model and year that the part fixed. I really wish more people would do this, I find those reviews so helpful, and I always look at the most recent reviews as the first ones you see are not typically legit and created by the vendor or their friends. Happy Thanksgiving to everyone. Take care.

This was a change from my old Hayward system. I chose this based on reviews and price, as it was $600 less than Hayward just for the system itself, and the warranty lasts 4 years rather than 3, even though it’s prorated. While I can’t review it for longevity yet, I will tell you I like the window that allows me to see salt value without opening the box. It was pretty easy to install, and within minutes was reading values and working perfectly. I’m not sure about this, but I think Hayward requires you to have their system professionally installed to use the warranty. Price of the Hayward system alone was over $1800, and pricing for installation added $800 more, for a total of $2600. This one was about $1100. No brainer to me.

UPDATE: We were having a problem with our pool about a year after installing a CircuPool salt generator and I was pretty certain that it had something to do with the CircuPool system. I called their customer service and talked to John Hill who gave me some suggestions, and then gave me his direct email address and direct phone number (!!!). When his suggestions did not fix the problem, we exchanged a number of emails until the problem was solved. There was not a problem with the CircuPool - just excessive phosphates in the pool (which we had never experienced before). He nailed the issue and patiently worked through the problem with me. Excellent customer service! Soooo much better that the company that made our previous overpriced salt generator and provided lousy, costly, customer service. Highly recommend the CircuPool! Original Review: We have had this unit running for about three weeks at this point and it is operating perfectly. We previously had a major brand that rhymes with "wayward" (but starts with a "H") and attempted to replace circuit boards on that unit that were fried after about 8 years of use. The company and its authorized reps in our city were not helpful and wanted $2,500 to replace the whole unit. After research, we decided to go with the Circupool Universal40 Saltwater Chlorinator at much lower cost. Wired the unit same as old unit, connected the cell to the old fittings, did not replace flow sensor with the new one provided (used old one already plumbed in), and everything fired up properly and sanitized the pool overnight. Gin clear water ever since. Happy customer!

I have had the unit installed a little over a year. Install went fine though it took several days after the salt level was good before it accurately reflected the salt level and started making chlorine. The maint light came on in the fall for cleaning and the cell cleaning was performed per instructions. However the maint light still periodically flashed on/off. Now for the bad part. We went out of town, and when we left the chlorine was reading 3500 -- pool has been in service since May. When we returned the chlorinator was not producing and now indicated low salt. I took a sample to Leslie's pool and the salt was low. Performed another cell cleaning based on tips in the manual even though there was zero residue visible. Added salt 3 weeks ago and after testing the level was 3800. After about 2 weeks the salt updated to 2800 and the unit started producing salt. Lasted about a week and now it says the salt level is 2500 when in fact it is 3300. I have exhausted all fixes found in manual and online. It is maddening to be adding chlorine to a pool when I spend so much for the chlorinator. I. Going to call service today after waiting on hold 45 minutes last time and finally hanging up. I am updating back to 2 stars as I finally reached support. Not an ideal process as I have to remove the cell and send it to them for testing even though the support person indicated that it appears to be the cell. Fortunately I plumbed with that section for removal during the winter with straight tube. Title 'Poor quality' as I did find other people complaining of same issue.

I bought a chlorinator from the Hayward brand. First I bought a used one thinking it might just be an open box on Amazon. Big mistake. I inspected and saw algae and cracks and sent it back. Then bought a new Hayward unit That one was a lemon as the salt meter was faulty. This was a huge time suck as I kept tearing apart my 2” pool plumbing. If this happens btw, do not keep adding salt. Go to your pool guy and test the water. Finally I went with this unit and brand hooked it up. And it works! What I like about this brand is the unit seems more solid. It was easier to hook up, and easier to operate. Little things such as they provided the electrical components so you did not have to purchase addition wiring. What I learned after going through 2 returns that Amazon was quick to blame the “third party” and the seller was quick to blame Amazon. The return was accepted but I had to make noise to get a shipping label and get them to accept a used return. And yes; I did got to Hayward and they confirmed that the unit was faulty. What I would say for something this expensive and specific; go direct to seller or use a local pool shop. If I did that I probably Would have been able to swap it out. I just kept getting a Hayward calling service that was no help. Hayward couldn’t help me as they needed it all To got through Amazon. Amazon said I needed to go through the seller (in the swim). So l was going round and round. Also, go with a bigger machine so you have some room. I have a 15,000 gallon pool and it good to go with a larger unit so you have some room.

This review is for the salt water skeptics or just on the fence about making the switch. I found I was using about $300 in chemicals every 4 months and a lot if time playing the water chemistry balancing act. So, after reading up on reviews and with the price point set where it's not a budget breaker I made the purchase of the Circupool Universal 40 unit. I first dissolved 200 lbs of required salt in my pool. The set up says to give it a couple days to correctly disolve and be usable. After receiving my Circupool unit I physically layed the components out along with the wires to be certain it would be a clean and professional install. I mounted the controller next to my pool timer....shut off power at the box and connected the 3 wires securely to the pool timer. 30 mins for this task. I carefully cut in and glued the flow control and the chlorine generator module. 30 mins for this task. After 20 mins of securing the wires with zip ties as the glued fittings dried I hit the power to the timer which fired up the entire system. All together let's say 1.5hrs from start to finish. 2 months in and pool looks sparkling great and has never had an imbalance yet. I test 2 times a week and all is balanced so far every time. The system is plug and play and at this point my pool timer shuts all down for 7 hrs every night. My system read out still shows balance and good Chem levels. I will add a bag or 2 of salt a year if the system readout reflect the need to do so....at $9 for a 40 lb bag. There are 2 other minor Chem balancing items that are at $13 to $20 for those and I have yet to need any of them. When somebody asks me......I say Go salt and enjoy your pool!

Excellent product...I haven't done anything to my my pool but clean It a few times, and the water is sparkling clear. Also you can open your eyes under water as the type of chlorine it produces is nearly as harsh as the tablets. Over all its expensive, but with the cost of pool chemicals m, it will pay for itself in a year. When I say I haven't had to do any chemical maintenance, I mean none...the water got low and I added another bag of salt..7 dollars...I love my pool again
