Why Choose Staypoollizer with Patented Nxgen?
Don't settle for cheap, short-lived auto-fill systems that fail under real-world pool conditions. Many budget autofillers rely on fragile plastic molded nozzles and exposed tank assemblies that bear the full brunt of fluctuating water pressures, water hammer effects, and aggressive mineral-laden water. Over time, these designs lead to cracking, erosion, leaks, and premature failure—often requiring frequent replacements or add-on regulators that add complexity and cost.
The Staypoollizer 2.0 with Nxgen Flow Control changes everything with its patented, self-contained stainless steel nozzle system:
- All pressure contained within the Nxgen nozzle — Unlike common plastic-based autofillers, where the entire tank assembly is constantly exposed to incoming water pressures (often spiking higher at night due to lower demand on municipal lines), Nxgen isolates and manages all hydraulic forces internally. This eliminates stress on external components, prevents water hammer damage, and dramatically reduces wear.
- Superior stainless steel construction — The Nxgen features a precision-engineered solid stainless steel nozzle that resists corrosion, harsh pool chemicals (including saltwater), and abrasive mineral "jet cutting" that erodes plastic inlets over months or even weeks. Plastic molded inlets struggle with daily pressure swings, extreme temperature changes (hot days to cool nights), and mechanical stress at the water source connection point—leading to cracks, leaks, and inconsistent performance. Nxgen's stainless design handles pressures from 1 to 200 psi without needing a separate regulator, delivering unmatched longevity.
- Improved flow and reduced workload — By containing pressures and optimizing laminar flow within the closed Nxgen system, the unit operates more efficiently—reducing mechanical stress by over 300% compared to all-plastic alternatives. This means smoother, more reliable shut-off, less turbulence, and far fewer maintenance headaches.
- Built to last, not just to sell — Cheaper systems may seem like a bargain upfront, but hidden costs add up fast: repeated part replacements, water waste from leaks/overfills, pump strain from low levels, and even algae issues from inconsistent water levels. Nxgen delivers pro-grade durability trusted by pool professionals and owners worldwide- lasting years with minimal upkeep.
With Staypoollizer Nxgen, you get a set-it-and-forget-it solution that truly maintains perfect water levels 24/7, conserves water, protects your pool equipment, and gives you more time to enjoy your pool—not worry about it.
Upgrade to the Nxgen difference today—because your pool deserves better than "cheap enough."
Let customers speak for us
from 138 reviewsGreat fitting. Well built and seals well.
I had a problem with corrosion on a unit just past the warranty. I talked to the company and they made everything ok.
I highly recommend this product.
Problem with original not shutting off began for me when the washer used to stop the flow apparently changed to a neoprene washer. The newly designed unit supported by the Nxgen stainless steel valve control solved my problem. I am once again confident leaving the 2.0 unit operational in our seasonal home in Florida. I knew it would shut off as soon as I received the 2.0 and looked at the stainless steel construction of the shut-off valve. You can easily spend hundreds of dollars on other valves and water bills (I did). Save yourself some trouble and money with the Staypoolizer 2.0.
I love Staypoollizer. It keeps my pool at the proper fill level and works flawlessly. Customer Support is outstanding. I had some questions, and they called me back quickly and spent as much time as I needed to get my questions answered.
Very easy to rebuild the product with this kit. Prompt shipment as well.
Been using these ever since my pool was installed 8 years ago. These work perfectly to keep the pool filled.
My original leveler lasted 10 years. Purchased the unit part /Float assembly only. Easy to install.
The constant stress about having to remember to fill the pool is finally over. This product works great, especially since we travel a lot and having someone come over to fill my pool was draining. Thank you.
Alleviated the weekly routine of having to refill our pool. High-quality product.
Easy to install and great price.
Rebuild Kit was the perfect fix.
Great Pool Filler - Wonderful People to do Business With
Solid built. Would recommend to others.
Very nice
Solid built, and way heavier than it looks.
The stainless steel fitting are a nice touch, first class in my opinion. Very happy with the quality.
Super simple to install. If you're looking for a real nice auto filler, I think this is the one.
The quick connect is a nice addition, super easy to swap out to a spray nozzle when needed.
Appears to be very high quality and simple to set up.
