How to drain a swimming pool?


Draining a swimming pool is an essential maintenance task that may be required for various reasons, such as cleaning, repairs, or winterization. While it may seem like a daunting task, with the right knowledge and tools, it can be done efficiently and effectively. In this article, we will explore the step-by-step process of draining a swimming pool and provide helpful tips along the way.

Preparing for Draining

Before you begin draining your swimming pool, it is crucial to take certain precautions and gather the necessary materials. Here are the key steps to follow:

1. Check local regulations: Before draining your pool, familiarize yourself with any local regulations or restrictions regarding the discharge of pool water. Some areas may have specific guidelines to protect the environment or prevent water waste.

2. Gather the required tools: To drain a swimming pool, you will need a submersible pump, a garden hose long enough to reach a suitable drainage area, and a power source for the pump. Additionally, you may need a pool vacuum or skimmer net to remove any debris from the pool before draining.

3. Test the water chemistry: Before draining the pool, it is advisable to test the water chemistry using a pool testing kit. This will help you determine the chemical levels and adjust them if necessary before refilling the pool.

Draining the Pool

Once you have prepared for the draining process, follow these steps to effectively drain your swimming pool:

1. Turn off the pool equipment: Before starting the draining process, turn off all the pool equipment, including the pump, heater, and any other electrical components. This will prevent any damage or accidents during the draining process.

2. Connect the submersible pump: Place the submersible pump in the deepest part of the pool and connect it to a garden hose. Ensure that the hose is long enough to reach a suitable drainage area, such as a storm drain or a designated area on your property.

3. Start the pump: Once the pump and hose are properly connected, submerge the pump in the water and turn it on. The pump will start removing the water from the pool and transferring it through the hose to the drainage area.

4. Monitor the process: Keep an eye on the draining process to ensure everything is functioning correctly. Check the pump regularly to ensure it is working efficiently and that the water is flowing smoothly through the hose.

5. Remove debris: While the pool is draining, use a pool vacuum or skimmer net to remove any debris that may be floating on the water’s surface. This will prevent clogging the pump or causing any damage during the draining process.

6. Adjust the drainage rate: Depending on the size of your pool and the drainage area, you may need to adjust the drainage rate to prevent flooding or overwhelming the drainage system. If necessary, regulate the flow by adjusting the pump’s settings or using a flow control valve on the hose.


Draining a swimming pool is a task that may be required for maintenance purposes. By following the step-by-step process outlined in this article, you can successfully drain your pool while ensuring the safety of your equipment and the environment. Remember to check local regulations, gather the necessary tools, and monitor the process closely. Always take precautions and consult professionals if you are unsure about any aspect of the draining process.
