It’s critical to comprehend the procedure and take the appropriate safety measures when draining an in-ground pool to protect both you and the pool. We’ll walk you through each step of draining an in-ground pool in this article, from safety measures to preparation to actual draining and cleanup. Additionally, we will discuss some potential issues that might occur, offer solutions, different drainage options, and the significance of preservation and maintenance.

Safety Precautions

When performing any kind of pool maintenance, safety should always come first. To prevent any mishaps or injuries, it’s essential to turn off all electricity to the pool before starting the draining process. Make sure you are familiar with the electrical setup of your pool and are aware of how to shut off the electricity to the pump, filter, and any other electrical parts. It’s also crucial to remember that before beginning the draining process, any electrically powered equipment, such as an automatic pool cleaner, needs to be turned off.

Wear the proper safety equipment, such as gloves and goggles, to protect your eyes and skin from any chemicals or debris that may be present in the pool in addition to turning off the electricity. Remember that water is very heavy and that if a pool is not properly drained, the weight of a full pool can harm the pool’s structure. It’s critical to understand the weight of the water and take the appropriate safety measures to safeguard both you and your pool.

Preparing to Drain the Pool

Finding the main drain and skimmer valves is the first step in draining an in-ground pool. These valves, which usually control the flow of water out of the pool, are found at the bottom of the pool. Before starting the draining procedure, it’s crucial to become familiar with where these valves are located.

You should also close off any additional pool valves or openings that might be related to the plumbing system. Any return pipes, spa jets, or other plumbing-related openings on the pool’s plumbing system are included in this.

It’s important to make sure the pool pump is in good working order before beginning the draining process. The water must flow through the pool’s filters and back into the pool with the help of the pool pump. If the pump is not functioning properly, it might not be able to handle the water flow during the draining process, which could cause damage to the pump or other plumbing system components of the pool.

Before beginning the draining process, it is best to have your pool pump inspected by a professional if you are unsure of its condition.

Draining the Pool

You can start draining the water once you’ve prepared the pool and become familiar with the valves. Start by allowing the water to drain out of the pool by opening the main drain and skimmer valves. Monitor the water level in the pool and change the valves as necessary to regulate the water flow.

It’s crucial to avoid draining the pool too quickly because doing so could harm the pool’s construction. You might need to adjust the valves or seek professional assistance if you notice that the water level is dropping too quickly.

In order to keep the water level in the pool at a safe level as it drains, it’s also crucial to keep an eye on it. The plumbing system or the pool’s frame may be harmed if the water level falls too low. It’s best to turn off the valves and seek professional assistance if you see that the water level is getting too low.

Close the valves after the pool is empty. Even after the valves have been closed, it’s crucial to monitor the water level in the pool because there might still be some water in the plumbing system. This water will eventually drain out, but it’s crucial to wait until it has done so completely before moving forward.

Finishing Up

It’s critical to check the pool for any damage or leaks after it has been drained. Check the pool’s structure for cracks or other indications of damage, as well as any plumbing leaks. It is best to get professional assistance to fix any damage or leaks before filling the pool.

If any debris accumulated during the draining procedure, clean the pool and remove it. This includes any debris that may have gathered in the pool’s filters or other plumbing-related components. Reinstall any components, like the main drain or skimmer covers, that were taken apart during the draining procedure.

You might think about adding water to the pool after draining it, depending on the cause. To avoid harming the pool’s plumbing system or structure, it’s important to slowly refill the pool if you intend to do so. Before refilling the pool, it’s important to check the water’s chemical balance and make any necessary adjustments.

Potential Problems and Solutions

An in-ground pool’s draining process can be difficult at times. Low water pressure, for instance, may be caused by a clogged drain that makes it difficult for water to drain from the pool. You might need to use a pool vacuum or other tools to clear the clog if you run into this issue.

Another problem that might occur is if the water level in the pool drops too quickly. If this happens, the pool may sustain structural damage. You should keep an eye on the water level in the pool and change the valves as needed to regulate the water flow to prevent this.

It is best to get professional assistance if you have any issues while draining. A pool expert will be knowledgeable and skilled in troubleshooting and resolving any problems that may occur. In order to avoid any damage or leaks, they will also be able to offer instructions and guidance on how to properly drain your pool.

Alternative Drainage Methods

There are alternatives to using the main drain and skimmer valves, which is how in-ground pools are typically drained. You could, for instance, rent a pool drain vacuum or use a pool pump to drain the pool. Each approach has its own advantages and disadvantages. Using a pool pump, for instance, might be quicker but also more expensive. Although renting a pool drain vacuum might be less expensive, it also takes more work to operate.

A pool pump is an alternative method for draining a pool, but it requires a large volume of water to operate and might not be the best choice for smaller pools. As you must connect hoses to the pump and direct them to the proper drainage area, using a pool pump necessitates more setup and preparation.

A pool drain vacuum, on the other hand, is a less complicated option. This gadget uses suction to draw water out of your pool and attaches to the skimmer. It’s a fantastic alternative for people who don’t have access to a pump or don’t have a lot of water to pump out. It’s crucial to remember that using a pool drain vacuum can be challenging and may involve more work than using a pool pump.

Maintenance and Preservation

The process of draining an in-ground pool shouldn’t be done frequently. Your pool’s regular upkeep and maintenance can help reduce the need for frequent draining. This entails preserving the proper chemical balance, cleaning the pool and its filters frequently, and carrying out regular inspections. You can extend the life of your pool and lessen the need for frequent draining by keeping it clean and well-maintained.

Additionally, purchasing a pool cover can help keep the water in your pool from evaporating, lowering the frequency of draining and refilling. In the long run, a pool cover can help you save time and money by lowering evaporation and keeping debris out of the pool.

It’s also crucial to keep in mind that draining an in-ground pool may have an effect on the neighborhood, especially if the water is being dumped into a natural body of water. It’s critical to think about the potential effects of draining your pool and take the necessary precautions to reduce any unfavorable outcomes. Before draining your pool, you might want to consult with regional or environmental authorities.


Although draining an in-ground pool may seem like a difficult task, it is manageable with the right planning and information. Always put safety first, and before beginning the process, turn off the electricity to the pool. Locate and prepare the main drain and skimmer valves correctly.

Check the pool’s water level and look for any potential issues. Consider enlisting the assistance of a professional if you’re uncertain about any step in the procedure. Additionally, keep in mind that routine maintenance can lessen the need for frequent draining.

Finally, it’s critical to keep in mind that draining an in-ground pool is a serious undertaking. To ensure that the process is carried out safely and effectively, it requires appropriate planning, knowledge, and the appropriate tools.

You can make sure that your pool is properly drained and that any potential issues are dealt with before they turn into bigger problems by following the instructions provided in this article.
