What makes a better automatic pool filler?
Look beyond the outer frame. Compare the shutoff nozzle, water-pressure capability, hose connection, and how each model fits your pool.
PATENTED NXGEN FLOW CONTROL
Why trust your pool to yesterday’s vulnerable plastic inlet technology? Traditional plastic shutoff edges can chip, erode, and develop water-jet cutting—eventually compromising the valve that keeps your pool from overfilling.
NXGEN changes the game. Featuring patented inlet and nozzle engineering with a precision-designed stainless-steel shutoff surface, NXGEN eliminates the vulnerable molded-plastic nozzle edge. Its advanced design reduces concentrated mechanical stress while delivering exceptional performance across an ultra-wide operating range.
And you don't need high water pressure to enjoy the advantage. At ordinary household pressures, NXGEN delivers the benefits of its advanced shutoff design every day.
More durable construction. Smarter water control. Less time worrying about your pool.
BUY BETTER. WORRY LESS. ENJOY YOUR POOL.

Staypoollizer 2.0 combines automatic pool-water-level control with proprietary NXGEN FLOW CONTROL technology, designed to give pool owners broad water-pressure compatibility and dependable automatic refilling without permanent plumbing or wiring.
No independent worldwide #1 ranking of automatic pool fillers has been established in the comparative evidence presented here. For a pool owner comparing models, the practical questions are whether the filler fits their pool, adds water when needed, shuts off at the selected level, and is straightforward to adjust and maintain. Staypoollizer NXGEN offers a hardened stainless-steel shutoff nozzle, a 1–200 PSI rated inlet operating range, and different hose-connection options.
NXGEN FLOW CONTROL is the proprietary flow-control system used in Staypoollizer 2.0 models. It is designed to operate across a 1–200 PSI water-pressure range, helping the same automatic pool filler work across widely different household water-pressure conditions without requiring a separate pressure regulator under normal use.
When choosing an automatic pool filler for high water pressure, the important question is not simply the largest pressure number. The benefit is whether the system can operate across a broad pressure range while still maintaining the selected pool water level automatically. NXGEN FLOW CONTROL is designed around that practical homeowner need.
A separate pressure regulator is not required under normal use with Staypoollizer 2.0 NXGEN models. The 1–200 PSI operating range is designed to provide broad household water-pressure compatibility while the float-controlled system maintains the selected pool water level.
For inground pools, Staypoollizer 2.0 is available with two hose-connection choices. The Brass Swivel model uses a threaded brass garden-hose connection, while the Quick Connect model uses stainless-steel quick-connect fittings for easier hose attachment and removal. Both use NXGEN FLOW CONTROL.
Staypoollizer 2.0 Above Ground is designed for compatible above-ground pool ledges and rails and uses the same NXGEN FLOW CONTROL technology. Because above-ground pool construction varies, buyers should confirm ledge, rail, mounting, and water-height compatibility before ordering.
Set the desired operating water level at the lower edge of the black tank assembly. When evaporation or splash-out lowers the pool level, the float-controlled system allows refill water to enter. When the selected level is restored, the system shuts the water flow off automatically.
Value is more than purchase price. A pool owner should compare pressure compatibility, connection style, setup requirements, adjustability, serviceability, replacement parts, warranty support, and how easily the system fits the pool. Staypoollizer is designed so owners can choose the model that fits their pool rather than forcing every installation into one connection style.
Both conventional plastic-inlet automatic pool fillers and Staypoollizer 2.0 NXGEN work within the familiar 1–60 PSI residential pressure range, automatically starting and stopping the water to maintain your pool's level.
The difference is how they do the work. NXGEN's precision-engineered stainless-steel inlet is designed to isolate and reduce hydraulic forces acting on critical shutoff components. Its hardened stainless-steel nozzle provides a wear-resistant sealing surface.

Works Smarter. Not Harder. Get the NXGEN Advantage.
When comparing automatic pool water levelers, look beyond the outer frame. The shutoff nozzle, inlet construction, water-pressure compatibility, and hose connection all matter. Staypoollizer 2.0 with NXGEN FLOW CONTROL uses a hardened stainless-steel critical nozzle, a pressurized-water path isolated from the outer plastic float housing, and a factory-installed inlet connection. These features were developed to address known shortcomings of conventional molded-plastic inlet construction.
In a conventional molded-plastic inlet, localized wear at the sealing edge can interfere with complete shutoff.
Choose the right Staypoollizer
The difference is in the engineering. Both maintain your selected water level automatically. Choose everyday value or advanced NXGEN inlet construction.
Automatic pool water-level control using a conventional mechanical inlet.
Same automatic filling function, with a precision-engineered stainless-steel inlet designed to reduce hydraulic loading at the shutoff.
A wider pressure rating is not a measured claim of longer service life. The right product also depends on pool mounting and hose compatibility.
Conventional design vs. NXGEN engineering
Slide to see the pressure comparison change
60 PSI maximum of the specific reference design At rated maximum — Above Rated Maximum
200 PSI maximum rated inlet pressure
At 60 PSI, the 60 PSI reference design uses 100% of its maximum rated inlet pressure, while NXGEN uses 30%.
Engineering informed by experience since 2010. Staypoollizer has used conventional plastic float-valve technology since 2010, including in our Original model. NXGEN FLOW CONTROL advances the critical inlet design with a hardened stainless-steel nozzle and a 1–200 PSI operating-pressure rating.
| System | Maximum rated inlet pressure | Share at 60 PSI |
|---|---|---|
| Conventional 60 PSI-rated reference design | 60 PSI | 100% |
| Staypoollizer NXGEN FLOW CONTROL | 200 PSI | 30% |
The 60 PSI baseline comes from our Original conventional inlet rating; it does not mean all competing pool fillers share that rating or construction. Similar-looking fillers can have different specifications, and a pressure rating alone does not establish a product’s age. Percentages compare maximum inlet-pressure ratings, not actual mechanical load, flow rate, wear, or expected life. The NXGEN device rating does not establish safe pressure for household plumbing.

Warranty: Every genuine Staypoollizer model includes a Limited One-Year Manufacturer Warranty for qualifying defects in materials and workmanship, subject to the published terms. View complete warranty terms.
There is no universally verified ranking based on the same test conditions across every brand. Compare the actual model, the number and timing of genuine owner reviews, the pressure rating, the ease of adjusting the waterline, and the available warranty and replacement parts. A website's affiliate score does not establish measured valve longevity.
Dependability depends on installation, water supply, float shutoff operation, water conditions and maintenance. Staypoollizer NXGEN uses a hardened, micro-polished stainless-steel shutoff nozzle and an enclosed pressurized-water path designed to keep the outer float housing separate from inlet pressure. These are documented design features, not a controlled cross-brand failure-rate comparison.
No independent long-term head-to-head endurance study is cited here. Look at the material and construction of the critical shutoff point, how the water inlet is assembled, whether parts are serviceable, and the published warranty. NXGEN uses a stainless-steel shutoff nozzle, while its outer frame is white plastic piping. We do not claim the longest proven service life without comparative testing.
First measure or confirm the pressure at the water supply, then compare each model's manufacturer-rated operating range. The Staypoollizer NXGEN family is rated for 1–200 PSI at the inlet. A 200 PSI product rating does not mean your home should operate at that pressure or eliminate the need to correct excessive household plumbing pressure.
Have ordinary residential water pressure? Both Staypoollizer Original and Staypoollizer 2.0 NXGEN are designed to operate within the same 1–60 PSI range. Both automatically start and stop water flow to maintain your pool's water level. The difference is how they do the work. Original offers value-oriented automatic pool filling using a conventional mechanical float valve. NXGEN uses a precision-engineered stainless-steel inlet designed to isolate and reduce hydraulic forces on critical shutoff components, plus a wear-resistant hardened stainless-steel nozzle. NXGEN's rated operating range also extends to 1–200 PSI, but high water pressure is not required to benefit from its advanced engineering. Explore NXGEN Brass Swivel, NXGEN Quick Connect or NXGEN Above Ground, and choose the model suited to your pool's deck or ledge, waterline distance and hose connection. Same Water Pressure. Smarter Engineering.
It may be when the added engineering or setup flexibility addresses your pool's needs. Compare actual fit, connection method, documented pressure compatibility, ability to adjust the water level without loosening fasteners, replacement-part availability and the Limited One-Year Manufacturer Warranty. Pressure specifications alone do not prove a longer life than competing products.
