Above Ground Pool Hollowell 21 ft Steel Wall Pool with Sand Filter

Description

Product Overview

The Hollowell Industries 21‑ft above ground pool is engineered for families who want a reliable, high‑quality swimming experience without the permanent installation of an in‑ground pool. Constructed with a 52‑inch copper‑bearing steel wall, reinforced by resin‑filled top connectors, the pool delivers exceptional structural integrity that resists warping, denting, and corrosion even after years of seasonal use. The included 21‑ft pool liner is precision‑cut to match the exact dimensions of the steel frame, providing a seamless, watertight surface that eliminates leaks and reduces maintenance time. A powerful sand filter and pump system circulates water continuously, trapping debris, algae, and fine particles to keep the water crystal clear. The kit also contains a sturdy frame ladder rated for up to 250 lb, a thru‑wall skimmer for surface debris removal, and a comprehensive instruction manual that guides users through site preparation, assembly, and first‑time filling.

Usage

This pool is ideal for a wide range of outdoor environments, from suburban backyards with a level concrete pad to spacious rural properties with prepared ground. It thrives in warm summer climates, providing a refreshing escape for children, adults, and pets alike. The pool’s generous 21‑ft length and 52‑inch depth accommodate swimming laps, water games, and relaxation, making it suitable for family gatherings, birthday parties, and fitness routines. Because the pool sits above ground, it can be installed on a flat, level surface that has been cleared of rocks, roots, and sharp objects. Homeowners should ensure the ground is compacted and free of debris before assembly, and they may use a protective ground sheet to prevent punctures. The sand filter system operates quietly, allowing the pool to be used day or night without disturbing neighbors. Regular water testing and occasional filter media replacement keep the water safe and sparkling.

FAQ

What type of surface is required for installation?

The pool must be placed on a flat, level surface that is free of sharp objects, rocks, or roots. A compacted soil base, concrete slab, or specially prepared ground sheet works best. The surface should be level within 1/4 inch across the entire footprint to ensure even weight distribution.

How often should the sand filter media be replaced?

For optimal performance, replace the sand in the filter every 3‑5 years, depending on usage frequency and water quality. Regular back‑washing and occasional inspection of the filter element will extend its service life.

Can the pool be used in colder climates?

Yes, the pool can be winterized by draining the water, cleaning the liner, and storing the components in a dry location. Using a pool cover during colder months helps protect the liner and reduces the risk of damage from freezing temperatures.

Is the ladder weight‑rated for adults?

The included frame ladder is rated for up to 250 lb, making it safe for most adults and children. It features non‑slip steps and a secure locking mechanism to ensure stable entry and exit.

What maintenance is required to keep the water clear?

Regularly skim the surface, clean the filter cartridge, and test water chemistry at least once a week. Adding a small amount of chlorine or a compatible sanitizer will help prevent algae growth and maintain a healthy swimming environment.
