Choose the Frame That Fits Your Pool Deck

Staypoollizer 2.0 models feature an adjustable upper frame designed to fit most pool-deck angles. Staypoollizer Original uses a proven fixed T-shaped frame and requires a flat, stable, compatible mounting surface.

Staypoollizer 2.0 adjustable-frame advantages:

  • Fits flat, tapered, and raised-edge pool decks
  • Rear legs rotate for better deck contact
  • Helps support the frame on common coping styles

Where Is My Water Going

Your pool loses water naturally from sun, heat, wind, evaporation, splash-out, and normal use. Staypoollizer helps replace that lost water automatically, so your water level stays where it belongs with less manual refilling.

  • Replaces water lost from normal evaporation and splash-out
  • Helps reduce constant hose checks
  • Great for hot weather, travel days, and everyday pool use

Common Questions Before You Buy

Do I need a pressure regulator?

No. Staypoollizer 2.0 NXGEN operates from 1–200 PSI and does not require a separate pressure regulator under normal residential use.

Does Staypoollizer need electricity or plumbing?

No. Staypoollizer connects to a standard garden hose and does not require wiring, drilling, or permanent plumbing.

How do I adjust the water level?

Slide the black tank assembly up or down. The bottom of the black float assembly lines up with the desired pool water level.

What hose should I use?

Use a good-quality garden hose with brass end fittings and a good washer. Avoid aluminum hose ends because they can corrode and fuse to brass or stainless fittings.

Which model should I choose?

Choose Brass Swivel or Quick Connect for in-ground pools. Choose Above Ground for above-ground pools.
