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

Draining an above ground pool quickly is a task many homeowners face at the end of the swimming season or when performing a major cleaning. Whether you are looking to winterize your pool or simply need to swap out the water, doing it efficiently saves time, energy, and prevents potential damage to the pool structure. This guide walks you through the fastest and safest methods to get the job done right.

Choosing Your Drain Method

The first step in learning how to empty above ground pool fast is selecting the right technique. You generally have three options: using the pool’s existing drain plug, employing a submersible pump, or utilizing a manual hose siphon. Each method has its advantages, but for sheer speed, an electric pump is typically the champion. The drain plug is the simplest solution if your pool is already positioned on a low, sloped area where gravity can do the work. However, if the ground is level or raised, you will need mechanical assistance to move the water efficiently.

Preparing the Pool for Rapid Drainage

Before you activate the pump or pull the plug, preparation is critical for a fast and safe process. You should never simply blast the drain setting without taking a few key steps first. Start by testing the water to ensure the pH and chlorine levels are balanced, which prevents overly aggressive water from damaging surrounding landscaping or concrete. Next, remove the skimmer basket and any pool accessories like ladders or return jets. Finally, clear a path for the water to exit, ensuring the discharge area is stable and won’t erode under the force of the flow.

Using a Submersible Pump

For the fastest results, a submersible utility pump is the industry standard. These pumps are designed to move large volumes of water quickly and can empty a standard above ground pool in a fraction of the time it takes for gravity drainage. To use one, place the pump in the deepest part of the pool and secure a garden hose to the outlet. Run the hose to a safe drainage area, ensuring the discharge is directed away from the pool’s foundation and any delicate landscaping. This method is so effective that it is often the go-to choice for professional pool cleaners.

Utilizing a Hose Siphon (DIY Gravity Drain)

If you do not have access to electricity, a hose siphon is the best alternative for speed. This method uses gravity and atmospheric pressure to drain the pool without a pump. To set it up, take a long section of hose and fill it completely with water, either by submerging it underwater or running it under a faucet until all the air escapes. Quickly cap one end with your thumb and place that end into the pool. Lay the other end on the ground lower than the pool, creating a downhill slope. Once you release the cap, the flow will initiate, and the siphon will pull water out rapidly until the level equalizes.

Safety and Structural Considerations

Speed is important, but safety is paramount when dealing with large volumes of water. Never let the pool empty completely if the groundwater in your area is high; the hydrostatic pressure from underground water can cause the empty walls to collapse or the liner to pop out of place. It is generally safer to drain the pool until there is about one foot of water remaining, then use a pool brush to loosen debris and finish the job with a wet/dry vacuum. Additionally, be mindful of where you discharge the water; directing it toward your neighbor’s property or a municipal storm drain can lead to fines or damage claims.

Post-Drain Maintenance

Once the water is gone, the fast part is over, but the job is not finished. Immediately after emptying, you should inspect the pool liner for any tears or stress points that may have occurred during the draining process. Use a shop vacuum to remove any sand, dirt, or debris that settled at the bottom during the draining process. This cleanup step is vital because scratching the liner while walking on a sandy floor can cause permanent damage when you refill the pool. Taking these steps ensures your above ground pool is ready for the next season with minimal risk.
