The short answer
Why Lower the Water Level
Heavy rain adds a lot of water to an already full pool. If the water rises above the skimmer, debris and runoff can enter the circulation system, and the pool can overflow into your yard. Overflowing water can pool against your foundation, seep into a basement, or wash away soil.
Lowering the level by 12 to 18 inches gives the rain room to collect without causing problems. That amount also keeps the pool functional for swimming after the storm passes. If you expect a very intense storm, check with local officials about any rules for draining pool water into storm drains or streets.
Use the Pool Pump's Waste Setting
Most pool filters have a waste or backwash setting that sends water directly to the drain line. Turn the multiport valve to waste, then start the pump. Watch the water level closely and stop when it drops to the desired depth.
This method works fast but sends a lot of water out at once. Make sure the discharge hose is directed to an area that can absorb the water, like a lawn or a dry well. Avoid sending chlorinated water into a garden or a storm drain if local rules forbid it.
- Turn off the pump before switching the valve.
- Check the discharge hose for kinks or blockages.
- Monitor the water level every few minutes.
- Stop when the water is 12 to 18 inches below the deck.
- Switch the valve back to filter before turning the pump on again.
Use a Submersible Pump
If your filter system is not working or you need to drain faster, a submersible pump can do the job. Place the pump on a step or a shallow shelf so it does not pull in debris from the bottom. Connect a garden hose to the pump outlet and run the hose to a safe discharge point.
Submersible pumps are common rentals at hardware stores. They handle a high volume of water, but they also require electricity near the pool. Keep the pump cord and any extension cords away from standing water and use a ground fault circuit interrupter outlet for safety.
Siphon with a Garden Hose
For a small water level drop, a siphon works without any pump. Fill a garden hose completely with water, hold both ends up so no air remains, then place one end in the pool and the other end lower than the pool water surface. Gravity pulls the water out.
Start the siphon by placing the lower end in a bucket and letting water flow until it starts. This method is slow, so it works well for a 6 to 12 inch drop. Keep the hose end submerged to avoid air bubbles that stop the siphon.
What to Do After the Storm
After the storm passes, check the pool water level and the surrounding yard for erosion or standing water. If the pool overflowed, you may have water damage in a basement or crawl space. Look for damp walls, wet carpet, or a musty smell.
If you find standing water indoors, act quickly to remove it and dry the area. For large spills or soaked drywall, local water damage pros can extract water and set up dehumidifiers. If you live in Layton, keep your pool shutoff valve location written down so you can find it fast during an emergency.
- Inspect the pool deck for cracks or shifting.
- Check the skimmer and pump basket for debris.
- Look for water stains on basement walls.
- Run the filter for a few hours to clear the water.
- Test the water chemistry before swimming.

How much water should I drain before a storm?
Lower the level by 12 to 18 inches. That gives the rain room to collect without overflowing. Draining more than that may expose the pool liner or cause the pool to pop out of the ground if the water table rises. Check local rules before draining.
Can I drain my pool into the street?
Many areas restrict draining pool water into streets or storm drains because of chlorine and other chemicals. Direct the discharge to a lawn or a dry well if allowed. Check with your local utility or city office for specific rules. Never drain into a septic system.
What if my pool overflows during the storm?
Overflowing water can seep into your basement or crawl space. After the storm, remove standing water quickly to prevent mold and structural damage. If water soaked into drywall or carpets, local water damage pros can handle the extraction and drying. Act fast to limit damage.
