How to Drain a Swimming Pool: Fast, Easy Methods Explained

KNowing how to drain a swimming pool may seem like a daunting task, but with the right equipment and approach, it can be done efficiently. Whether you need to empty your pool for maintenance, repairs, or cleaning, using a submersible water pump is one of the most effective methods to remove water quickly and easily.

Why Would You Need to Drain Your Pool?

There are several reasons you might need to drain your pool:

• Repairs: If your pool liner has sustained damage, draining the pool is often necessary to make repairs.
• Cleaning: Over time, debris, algae, and other contaminants can build up in your pool, and a deep clean may require complete drainage.
• Winterising: Preparing your pool for winter in cold climates may require draining the water below the skimmer level to avoid damage from freezing.

How Can I Empty My Pool Water Fast?

The fastest and most efficient way to empty your pool is by using a submersible water pump. These pumps are designed to be placed directly into the pool, where they will suck up the water and discharge it through a connected hose. Unlike manual methods, a submersible pump can work continuously, making it ideal for quickly draining large amounts of water.

How to Drain an Above-Ground Pool With a Sump Pump

To begin, it’s important to choose the right pump. For fast and efficient draining, a high-capacity submersible water pump is the best option. This will ensure that the water is removed quickly and effectively.
Next, you’ll need to connect a hose to the pump. Attach the discharge hose securely, and make sure the other end is placed in a safe area where the water can drain away without causing any issues.
Once the hose is in place, lower the pump into the pool. It’s most effective when submerged in the deepest part of the pool, as this allows the pump to remove water more efficiently.
Finally, power on the pump. Once activated, it will start draining the water from the pool. Keep an eye on the drainage process and adjust the hose as needed to ensure smooth operation.
Using a submersible pump is not only fast but also minimises the hassle associated with syphoning or using a garden hose.

How Do You Drain a Pool Easily?

If you’re looking for how to drain your swimming pool easily, again, submersible water pumps are the go-to solution. Their simplicity and reliability make them a favourite among pool owners. Once installed, they require minimal supervision, allowing you to go about your day while the pool drains itself.

Some additional tips for a smooth drainage process:

• Ensure the hose is long enough to reach a proper drainage area.
• Regularly check local regulations regarding where pool water can be discharged.
• For ease of use, select a pump with automatic shut-off features (Internal link to a specific product).

How Do You Get Water Out of a Pool Without a Pump?

While a submersible pump is the most efficient tool, there are other ways to remove water if a pump isn’t available.

Syphoning uses a long hose to create a syphon, allowing water to drain. While it works, it’s slower and less efficient than using a pump.

Some pools have a built-in drain plug for drainage. However, these drains are often less effective and may leave water at the bottom, requiring manual removal.

That said, using a pump is still the easiest and most efficient method, especially for large pools or if you need to empty your pool quickly.

Frequently Asked Questions About How to Drain an Above-Ground Pool

How long does it take to drain a pool?

The time it takes to drain a pool depends on several factors, including the pool’s size, the drainage method, and water flow rates. Here are typical time estimates:

• Standard Backyard Pool (15,000–20,000 gallons):
  • Using a Submersible Pump: 8 to 14 hours, depending on the pump’s strength.
  • Using the Pool’s Pump: 6 to 12 hours, though this can vary if the pump isn’t designed for draining.
• Large Pools (over 20,000 gallons):
  • May take up to 24 hours or more with a submersible pump.
• Smaller Above-Ground Pools (5,000–10,000 gallons):
  • Can take 4 to 8 hours using a submersible pump.

The speed can be affected by factors like the pool’s depth and local regulations on water drainage.

How far down should you drain a pool?

The amount you should drain a pool depends on what you’re planning to do. For general maintenance, you usually drain the pool just enough to perform the necessary tasks, such as cleaning the bottom or inspecting the equipment. Typically, this means draining it to about 6-12 inches below the skimmer or the level where you can easily access the pool floor.

Is it OK to drain a pool and leave it empty?

It’s generally not safe to leave a pool empty for long periods due to risks like structural damage (pool “popping” out of the ground from groundwater pressure), cracking of pool surfaces (especially concrete or vinyl liners), and equipment damage (drying out or corrosion). Prolonged exposure to sunlight can also harm the pool’s surface.

How do I know if my pool needs to be drained?

You may need to drain your pool for several reasons. High Total Dissolved Solids (TDS) above 2,500 ppm can make water quality hard to manage, requiring a drain. Excessive Cyanuric Acid (CYA) over 100 ppm reduces chlorine effectiveness, so fresh water is needed.

Persistent algae growth that won’t clear with treatments may also necessitate a full drain and clean. Major repairs or resurfacing projects often require draining the pool as well.

High calcium levels can cause scaling, making water replacement necessary. Lastly, heavily stained or dirty water may need draining if cleaning isn’t effective.
