Swimming pools are primarily emptied using a submersible pump, which is the most common and effective method for thorough water removal. This process is essential for various reasons, including routine maintenance, repairs, or addressing severe water quality issues.
The Submersible Pump Method
Emptying a swimming pool with a submersible pump involves a systematic approach to ensure efficient and safe drainage. This method allows for controlled removal of large volumes of water directly from the pool basin.
Here's a step-by-step guide to using a submersible pump:
- Prepare Hoses: Attach garden hoses to extend from the pool's edge all the way to an approved drainage point. It is crucial to ensure these hoses are long enough and positioned to direct water away from your property and into a designated area, such as a storm drain, sanitary sewer (check local regulations), or a safe, permeable landscape area that can handle the volume of water.
- Connect to Pump: Securely connect the other end of the hoses to your submersible pump's discharge outlet.
- Position the Pump: Carefully lower the submersible pump into the deepest part of the pool. Placing it at the lowest point ensures maximum water removal.
- Power Up Safely: Plug the pump into a GFCI (Ground-Fault Circuit Interrupter) outlet located near the pool. A GFCI outlet is vital for electrical safety, as it provides protection against electrical shocks, which is paramount when working with water and electricity.
Essential Equipment for Pool Emptying
| Equipment | Purpose |
|---|---|
| Submersible Pump | The core device for drawing and expelling large volumes of water efficiently. |
| Garden Hoses | Used to channel the expelled water from the pump to the drainage area. |
| GFCI Outlet | A safety feature crucial for preventing electrical shocks when operating the pump near water. |
| Safety Glasses | Recommended for eye protection during the process. |
Why Empty a Swimming Pool?
Pools are emptied for several key reasons, demonstrating the importance of this process in pool ownership:
- Major Repairs: Essential for structural repairs, resurfacing, or fixing leaks in the pool shell.
- Severe Water Imbalance: When chemical imbalances or persistent algae blooms are too severe to rectify with standard treatments.
- Winterization in Cold Climates: In some regions, pools are partially or fully drained to prevent freezing damage during winter.
- Relocation: Necessary if a portable or above-ground pool needs to be moved.
- System Upgrades: For replacing or upgrading plumbing and filtration systems located within the pool's structure.
Practical Insights and Considerations
- Local Regulations: Always verify local ordinances regarding pool water disposal. Many municipalities have strict rules about where pool water can be discharged due to its chemical content.
- Dechlorination: If draining into a storm drain or natural waterway, consider dechlorinating the water first to protect aquatic life.
- Monitoring the Process: Keep an eye on the pump's operation and the water level. Ensure the hoses remain in place and are effectively directing water away.
- Sediment Management: As the water level drops, sediment and debris at the bottom of the pool will become more concentrated. You may need to manually remove this sludge towards the end of the process.
- Pool Liner Protection: If your pool has a vinyl liner, avoid prolonged exposure to direct sunlight when empty, as this can cause the liner to shrink or crack. It's often best to refill immediately after cleaning or repairs.
By following these steps and considerations, emptying a swimming pool using a submersible pump can be a straightforward and effective part of pool maintenance.
