How to Empty an Above Ground Pool: Quick & Easy Guide

Homeowners with above ground pools often face the question of whether you can empty an above ground pool completely. While it might seem as simple as turning off the pump and letting the water drain, the reality involves several critical considerations to protect both the pool structure and your property.

Understanding Your Pool's Construction

The primary factor in determining if you can empty an above ground pool lies in its specific design. Unlike in-ground models, above ground pools rely on lateral pressure from the surrounding earth to maintain their structural integrity. When the water level drops below a certain point, this balanced pressure is lost, which can cause the walls to collapse or the liner to puckeringly pop out of place.

The Draining Process

To safely manage the water removal, you should utilize a submersible pump or a manual siphon rather than relying solely on the filtration system. If your pool has a sand or cartridge filter, backwashing it to the waste setting can initiate the drainage, but you must monitor the process constantly. Never leave an emptying pool unattended, as the structural failure can occur within minutes of the water level dropping too low.

• Use a wet/dry vacuum with maximum lift height capability.
• Connect a hose to the drain valve if your model is equipped with one.
• Disconnect any chlorine feeders or chemical lines before starting.
• Check the local sewer regulations regarding water disposal.

Risks of an Empty Pool

An above ground pool shell is designed to contain water; without it, the structure is vulnerable to environmental forces. Even if the pool is filled with dirt later, the weight of the soil during refilling or heavy rain can create uneven pressure, leading to permanent deformation or seam failure. Additionally, an empty basin can collect rainwater, turning into a mosquito breeding ground and a hazard for children or pets.

Protecting the Liner

If the decision to drain is permanent, removing the liner is the safest option for preserving its material. Storing a liner properly involves thorough cleaning, complete drying, and rolling it with a layer of protective paper to prevent creasing. Leaving the liner dry and exposed to sunlight UV rays will cause the vinyl to become brittle and crack, rendering it unusable for future seasons.

Winterization vs. Permanent Emptying

In regions with freezing temperatures, completely emptying an above ground pool is usually unnecessary and counterproductive. Water left in the system can freeze, expanding and tearing the liner or wall seams. The standard winterization process involves lowering the water level just below the skimmer return line, blowing out the pipes, and covering the structure to prevent precipitation accumulation.

When to Re-evaluate

There are specific scenarios where you might decide to empty the pool regardless of the risks. These include relocating the pool, switching to a different type of pool, or if the water has become irreparably contaminated. If this path is chosen, it is wise to consult the manufacturer's guidelines or a professional installer to ensure the process is executed without causing catastrophic damage to the pool frame.

Ultimately, while you can empty an above ground pool, it is a process that requires careful planning and strict adherence to safety protocols. Treating the structure with respect for its design limitations ensures that the pool remains a functional asset rather than a discarded piece of equipment.
