Why Would You Need to Drain an Inground Pool?
There are several reasons why you may need to drain your inground pool:
- Water chemistry issues that can’t be corrected
- Excess algae growth requiring a deep clean
- Repairing or resurfacing the pool
- Winterizing the pool in certain climates
- Routine maintenance after years of use
Draining your pool properly ensures safety and prevents damage to the pool’s structure.
Before You Drain Your Inground Pool: Important Considerations
1. Check Local Regulations
Some cities and counties have rules about where and how you can drain your pool water. Contact your local water authority before starting.
2. Avoid Draining During Hot Weather
Draining your pool in extreme heat can cause cracks in the pool shell or liner damage. Choose a cooler day for this task.
3. Be Aware of Groundwater Levels
If groundwater levels are high, your pool could pop out of the ground when emptied. If you’re unsure, consult a pool professional.
4. Know Where the Water Will Go
- Sewer system: Best option if permitted.
- Storm drain: Only if legally allowed.
- Irrigation/Lawn: Only if the water is chemical-free.
How Do You Drain an Inground Pool? Step-by-Step Guide
Step 1: Gather Your Supplies
You’ll need:
- Submersible pump (for faster drainage)
- Garden hose (if using the pool’s built-in drain system)
- Bucket or towels (for small spills)
- Long drainage hose (to direct water away from the pool area)
Step 2: Turn Off Pool Equipment
- Switch off the pool pump and filtration system.
- Unplug any electrical connections to prevent damage.
Step 3: Choose Your Drainage Method
Method 1: Using a Submersible Pump (Fastest & Recommended)
- Place the submersible pump in the deepest part of the pool.
- Attach a drainage hose to the pump and direct it toward a safe drainage area.
- Turn on the pump and monitor the water flow.
- Keep an eye on the water level as it drains.
Method 2: Using the Pool’s Main Drain (Slower but Effective)
- Attach a garden hose to the pool drain valve.
- Place the other end of the hose in a legal drainage location.
- Open the main drain valve.
- Let the water drain slowly over several hours.
Step 4: Monitor the Drainage Process
- Check for leaks or flooding around the drainage area.
- Adjust the hose if needed to avoid water pooling.
- Keep an eye on the groundwater level if draining fully.
Step 5: Remove the Last Few Inches of Water
- A wet/dry vacuum or bucket can help remove any remaining water.
- If there is debris or algae, use a brush and hose to clean the pool surface.
Step 6: Turn Off the Pump and Remove Equipment
- Unplug the submersible pump once the pool is empty.
- Disconnect and store the drainage hose properly.
After Draining: Cleaning and Maintenance Tips
Once your pool is empty:
- Scrub the pool walls and floor to remove dirt and algae.
- Inspect for cracks or leaks and repair if necessary.
- Let the pool dry completely before resurfacing or painting.
How to Prevent Damage When Draining a Pool
- Never leave an empty pool for too long – it can weaken the structure.
- Avoid draining if groundwater levels are high – it can lift the pool.
- Refill as soon as maintenance is complete to prevent surface cracking.
When to Call a Professional
If you are unsure about how to drain your pool, consider hiring a pool professional. Seek help if:
- Your pool is vinyl-lined, as draining can shrink the liner.
- You need major repairs after draining.
- There’s a high groundwater risk in your area.
