A Guide to Main Drains: Are They Required for an Inground Pool?

Updated: May 15

When it comes to installing an inground pool, there are several important factors to consider, and one of the most crucial is the need for a main drain. A main drain is an essential component of any inground pool, as it helps to circulate water, maintain proper chemical levels, and prevent the buildup of debris and contaminants. However, some pool owners may wonder whether a main drain is truly necessary or if it's simply an optional feature.  In this article, we'll take a closer look at the importance of main drains for inground pools and explore some of the reasons why they are essential for maintaining a safe, clean, and functional swimming environment.

Do I Need Main Drains for My Inground Pool?Yes, main drains are necessary for inground pools. Here are some of the reasons why:

1. CirculationA main drain is responsible for pulling water from the bottom of the pool and circulating it through the filtration system. This helps to distribute chemicals evenly throughout the pool and prevent stagnant water from forming.

2. Debris RemovalWithout a main drain, debris and contaminants can accumulate on the bottom of the pool, making it difficult to clean and maintain proper chemical levels. A main drain helps to remove this debris and keep the pool clean.

3. SafetyMain drains also play an important role in pool safety by preventing suction entrapment. Suction entrapment occurs when a person's body or clothing becomes trapped by the suction of a pool drain, leading to potentially dangerous or even fatal consequences. Main drains are designed with safety features to prevent this from happening.

4. ComplianceIn many areas, main drains are required by law for inground pools. Failure to install a main drain could result in fines, legal action, or even closure of the pool.

How Many Main Drains Are Necessary for Inground Pools?It is recommended to have at least two main drains for inground pools for safety reasons. This helps to prevent suction entrapment in case one of the drains becomes blocked or covered. However, the number of main drains required may vary based on local regulations and the size of the pool. It is important to consult with a professional pool contractor to ensure compliance with local laws and best practices for pool safety.

Benefits of Having Main Drains in Your Inground Pool?

1. Improved CirculationMain drains help to improve the circulation of water in the pool, allowing the water to be filtered and treated more effectively.

2. Enhanced Pool HygieneMain drains help to remove debris and contaminants from the bottom of the pool, ensuring that the water remains clean and hygienic.

3. Prevents Suction EntrapmentBy having multiple main drains, the risk of suction entrapment is greatly reduced. This is important for the safety of swimmers, especially young children.

4. Compliance with RegulationsMany areas require main drains to be installed in inground pools to comply with safety regulations. Failure to do so could result in fines or legal action.

5. Improves Pool MaintenanceMain drains make it easier to clean and maintain the pool, reducing the need for manual cleaning and upkeep.

ConclusionMain drains are a necessary component for an inground pool, as they play a significant role in ensuring the pool operates efficiently and safely. Main drains help to prevent stagnant water, and debris buildup, and ensure proper circulation and filtration of the pool water. Without main drains, the pool water could become contaminated and pose a health risk to swimmers.  Therefore, it is crucial to ensure that main drains are installed correctly and maintained regularly to keep your pool clean and safe for use. While there may be alternative options available, such as skimmers or bottom vacuums, they cannot replace the function of main drains in a pool. So, to enjoy a hassle-free and safe swimming experience, it is always recommended to have main drains installed in your inground pool.
