Why Do You Need to Drain a Pool?
Draining your pool is sometimes necessary for maintenance, cleaning, or repairs. Common reasons include:
- Water chemistry imbalance that can’t be corrected.
- Algae overgrowth requiring a deep clean.
- Repairs to pool surfaces or plumbing.
- Preparing for winterization in cold climates.
- Replacing pool water after several years of use.
Draining properly prevents damage to the pool liner, pump, and plumbing system.
Before Draining Your Pool: Important Considerations
1. Check Local Regulations
Some cities have rules about where and how you can drain 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.
- Lawn or Garden: Only if the water is chemical-free.
- Street Gutter: Only if local authorities allow it.
How to Drain a Pool with a Pool Pump: Step-by-Step Guide
Step 1: Gather Your Supplies
Before starting, you’ll need:
- Pool pump with drainage setting
- Garden hose or drainage hose
- Bucket or towels (for spills)
- Vacuum or submersible pump (optional for final water removal)
Step 2: Turn Off the Pool Equipment
- Switch off the pool pump and filtration system.
- Unplug any electrical connections to prevent damage.
Step 3: Set Up the Pool Pump for Draining
- Locate the multiport valve on your pool pump system.
- Turn the valve to the “Waste” or “Drain” setting.
- Attach the drainage hose to the waste port.
- Direct the hose toward the approved drainage area.
Step 4: Start the Pump to Drain the Pool
- Turn the pump back on.
- Monitor the water flow to ensure it is draining properly.
- Check the hose placement to prevent flooding or erosion.
Step 5: Remove the Last Few Inches of Water
- A wet/dry vacuum or a submersible pump can remove remaining water.
- Some pumps may not be able to drain all the way to the bottom.
Step 6: Turn Off and Remove the Pump
- Once the pool is fully drained, turn off the pump.
- Disconnect the drainage hose and remove the pump.
- Store the pump in a dry place to prevent damage.
Step 7: Clean the Pool Surface
- Scrub the walls and floor to remove algae or dirt buildup.
- Rinse the pool using a garden hose before refilling.
How to Prevent Pool Damage When Draining
- Never drain a pool on a hot day – high temperatures can crack the pool liner.
- Avoid draining below groundwater level – it may cause structural damage.
- Do not leave the pool empty for too long – it can weaken the pool’s foundation.
- Use a pool cover after refilling to maintain water quality.
When to Call a Professional
If you’re unsure about draining your pool, call a pool professional for help. Seek assistance if:
- Your pool has a vinyl liner (can shrink if emptied).
- You need repairs or resurfacing.
- There is a risk of pool popping due to high groundwater levels.
