Draining your pool may sound intimidating at first, but with the right tools and know-how, it’s a task that some pool owner can handle. Whether you’re dealing with algae, preparing for repairs, or refreshing your pool with clean water, knowing how to drain a pool correctly will help you avoid damage and keep your pool in good condition.

This guide will walk you through the steps to drain both in-ground and above-ground tp drain pools and offer expert tips to keep your pool safe during the process. If you’re unsure about doing this yourself, there are professionals ready to assist, such as 12 Pools Arizona, which offers services throughout regions like Gold Canyon.

Why You Might Need to Drain Your Pool

Draining your pool isn’t something you do frequently, but there are a few scenarios where it’s necessary:

  • Water Chemistry Imbalance: Over time, swimming pool water can become overloaded with chemicals, making it hard to manage. Draining and refilling can reset the water’s chemistry.
  • Repairs: Major pool repairs, such as fixing the pool floor or sealing cracks, usually require an empty pool.
  • Deep Cleaning: To remove tough algae or mineral deposits, sometimes the best approach is a thorough scrub after draining the pool.
    Winterization: If you live in a colder region, you might need to drain your pool to prepare it for winter.

That said, knowing when and how to drain a pool safely is important to avoid damage from hydrostatic pressure or pool pop, especially in regions like Arizona with high water tables.

Tools You’ll Need

Before you begin, gather these tools to make the draining process as smooth as possible:
Submersible pump: Best for quickly draining large pools.

  • Garden hose: Great for smaller, above ground pools or for siphoning water.
  • Pool hose: Useful for directing water out of the pool to a safe drainage area.
  • Sump pump: An option for smaller draining tasks or shallow pools.
  • Drain valve: Built into some pools to facilitate draining.

How to Drain a Pool: Step-by-Step Instructions

  1. Check Local Pool Drainage Rules
    Before starting, always check your local regulations regarding pool drainage. In some areas, like Gold Canyon, you may need to neutralize the chemicals in your pool water before draining it into the street or storm drains. Many municipalities require that the pool water be free of chlorine or at neutral pH levels before disposal. You can let the chlorine dissipate naturally by leaving the pool uncovered for a few days or using chemicals that neutralize chlorine.
  2. Turn Off the Pool Equipment
    Before you begin draining, make sure all the pool’s systems (like the filtration and pump) are turned off. Running the pool pump while draining can damage the equipment and is unnecessary for the draining process.
  3. Choose Your Draining Method
    a. Submersible Pump (For In-Ground Pools)
    For large or in-ground pools, a submersible pump is your best bet. Here’s how you can drain your pool using this method:
    Attach the pool hose to the pump.
    Place the pump in the deepest part of your pool.
    Ensure the other end of the hose leads to a suitable drainage area, as per local guidelines.
    Turn the pump on and monitor the process. This can take a few hours, depending on the size of your pool.
    It’s important to stay vigilant during the process, especially in areas with high groundwater levels. Hydrostatic pressure can build up beneath the pool, especially when the pool is empty, potentially causing a pool pop where the pool shifts or cracks. This is particularly common in regions like Arizona, where water tables can be high.
    b. Garden Hose Siphon (For Above Ground Pools)
    For smaller or above ground pools, you can use a garden hose to create a siphon:
    Submerge the hose completely in the water to fill it.
    While keeping one end in the pool, remove the other end and place it in your drainage area.
    Gravity will start pulling the water out through the hose. This method is slower but effective for smaller pools.
    Alternatively, if your above ground pool has a built-in drain valve, you can simply connect your hose to the valve and open it to let the water flow out.
  4. Monitor the Drainage Process
    As the water drains, keep an eye on it to ensure everything is flowing smoothly and the drainage area isn’t becoming overwhelmed. With in-ground pools, you’ll need to be cautious about the pool’s integrity as the water empties. Sudden shifts can cause structural damage, so avoid draining the pool all at once, especially during or after heavy rain.
  5. Clean the Pool
    Once your pool is empty, it’s the perfect time to thoroughly clean the pool walls and floor. Use a brush to scrub away any remaining algae, dirt, or mineral buildup. Look for any cracks or signs of damage that may need repairing before you refill the pool.
  6. Refill the Pool
    Once the pool is clean and you’re ready, you can begin refilling the pool with fresh water. Attach your garden hose to the water supply and start filling. Depending on the size of your pool, this can take several hours or even days. Be sure to monitor the filling process to prevent overflow.
    After the pool is refilled, you’ll need to rebalance the pool chemicals to ensure the water is safe for swimming. Check the chlorine levels, pH balance, and alkalinity to make sure everything is back to normal.

Additional Tips for a Smooth Pool Draining Process

  • Avoid Draining After Heavy Rain: Wet conditions can increase hydrostatic pressure, making it more likely for an empty pool to shift or crack.
  • Drain Slowly: For safety, it’s best to drain slowly over time. Fast draining can overwhelm your local storm drain or flood nearby areas.
  • Professional Help: If you’re unsure about the process, or if you have a larger project in mind like pool repairs or renovations, hiring a professional service such as 12 Pools Arizona can save you time and prevent costly mistakes.

Conclusion

Learning how to drain a pool is an important skill for every pool owner. Whether you’re dealing with an in-ground pool or an above ground pool, following the correct process can help you avoid costly mistakes like pool pop or damage due to hydrostatic pressure. By using a submersible pump or garden hose, draining water responsibly, and following safety measures, you can ensure your pool stays in top condition year after year.
