How to Siphon Water Out of An Inground Pool

As the proud owner of a sparkling pool, you’ve likely encountered those inevitable moments when the tranquility of your aquatic sanctuary must yield to the necessity of change. Whether it’s addressing essential maintenance, rebalancing chemical levels, or coping with the aftermath of nature’s downpour, the task of bidding adieu to a portion of your pool water becomes paramount.

In the realm of pool maintenance, the allure of modern pumps may hold sway, promising efficiency and ease. Yet, amidst this technological allure, there exists a time-honored method that often outshines its contemporary counterparts – the art of siphoning. This age-old technique unveils its brilliance, particularly when your pool’s liquid cargo seeks a lower elevation, beckoning the gentle guidance of gravity. However, before embarking on this aquatic venture, it’s imperative to ensure compliance with local regulations and select a drainage point that can gracefully receive the liquid offering you’re about to bestow.

So, let’s journey into the mechanics of siphoning water from your pool, armed with nothing more than a humble garden hose.

How to Syphon Water with A Hose?

When it comes to the task of extracting water from your pool, whether it’s an inground or above-ground one, there exists a straightforward yet highly efficient method that relies on the use of a garden hose. This technique, which requires only a few essential tools – a garden hose with a ¾-inch diameter and a hose cap – can make pool maintenance a breeze.

Now, let’s delve into a more in-depth, step-by-step guide for siphoning water from your pool, offering you a comprehensive understanding of the process:

  • Step 1: Begin by carefully submerging one end of your garden hose into the pool, ensuring that it is entirely immersed. Gradually fill the hose with water until it’s fully saturated.
  • Step 2: Lower the opposite end of the hose just below the water’s surface to make sure it’s completely filled with water.
  • Step 3: Take the hose cap and securely attach it to the open end of the hose. Alternatively, some prefer to create a watertight seal by bending or kinking the open end of the hose, effectively preventing any water from escaping.
  • Step 4: Elevate the end of the hose that is either capped or kinked, positioning it over your designated drainage area. It is of utmost importance to keep the capped or kinked end above the water source, avoiding any premature release until you are fully prepared to initiate the siphoning process.
  • Step 5: When you’re ready, remove the kink or cap from the hose’s end, and the water will begin to flow. Continue siphoning until you have reached your desired water level, ensuring a smooth and controlled process.
  • Step 6: After successfully siphoning the required amount of water, carefully detach the end of the hose from the pool and raise it to a higher point. This final step allows any remaining water within the hose to flow back into the pool, efficiently completing the task.

By diligently following these comprehensive steps, you can confidently and effectively remove water from your pool, ensuring its ongoing maintenance and optimal condition. This detailed approach guarantees a seamless water extraction process, ultimately keeping your pool in pristine shape.


How Long Does It Take to Syphon a Water?

The duration required to completely siphon water from your pool is contingent upon a multitude of factors, encompassing the pool’s dimensions, the quantity of water contained within, the caliber of the hose, and numerous other variables. However, on average, one can anticipate the process to conclude within a time frame spanning from approximately 8 to 14 hours.

Can I Syphon Water to an Uphill?

Unfortunately, it is not feasible to employ a syphon to move water to an elevated position. Syphoning is an effective method for transferring fluids, but it has its limitations. The practical height that a syphon can effectively lift water is approximately 10 meters above the source, such as a pool or reservoir. Beyond this height, a fundamental issue arises: the syphon can no longer maintain the continuous flow of water due to the formation of an air gap within the pipe. This air gap interrupts the syphoning process, rendering it ineffective.


In conclusion, it is crucial to exercise due diligence and adhere to local regulations when contemplating the drainage of your swimming pool. It is imperative to be aware of and comply with the specific guidelines that govern the discharge of pool water in your area. Local regulations may vary, and some jurisdictions may strictly prohibit the draining of pool water into streets or storm drains, while others may have specific protocols in place.

Furthermore, for those fortunate enough to have a pool equipped with a hydrostatic relief valve, it is essential to take the necessary precautions. Prior to initiating the drainage process, it is highly recommended to ensure that these relief valves are properly opened. Neglecting this crucial step can result in unintended consequences such as damage to the pool’s shell or deck, which can be both costly and troublesome to rectify.

In conclusion, by staying informed about local regulations and taking proactive measures like opening hydrostatic relief valves, you can ensure that your pool draining process proceeds smoothly and without any adverse consequences. This not only protects your pool’s structural integrity but also helps maintain a harmonious relationship with your community by adhering to local environmental regulations.
