Understanding Main Drains in Inground Pools: Two vs One Drain
Welcome to the Super Pools blog! Today, we're diving into a crucial aspect of inground swimming pools: main drains. While main drains are not required, especially if your pool is small and there is constriction on the plumbing space, our pool packages do come with them. Specifically, we'll explore the difference between having two main drains versus just one, the laws surrounding this issue, and why it matters for your pool's safety.
Why Main Drains Matter
Main drains are the openings at the bottom of the pool that draw water into the filtration system. They help keep the water clean and properly circulated. However, they also present a potential safety hazard, especially if not properly designed or maintained.
The Legal Landscape
In the past, many pools were built with just one main drain. Unfortunately, this setup posed a serious risk of entrapment, where swimmers could become trapped by the suction force of the drain. Tragic accidents occurred, prompting calls for stricter safety regulations.
In response to these incidents, laws were passed to require multiple main drains or other safety measures in new pool construction. The Virginia Graeme Baker Pool and Spa Safety Act (VGB Act), passed in 2007, mandated that public pools and spas have anti-entrapment drain covers and other safety devices to prevent accidents.
The Case That Changed Everything
The VGB Act was named after Virginia Graeme Baker, a young girl who lost her life in a pool accident in 2002. She became trapped by the suction of a faulty drain cover, despite efforts to rescue her. Her tragic death spurred her family to advocate for stronger pool safety regulations, leading to the passage of the VGB Act.
Two Drains vs. One Drain
One of the key provisions of the VGB Act is the requirement for multiple main drains or other anti-entrapment devices in new pool construction. This reduces the risk of entrapment by dispersing suction across multiple outlets, making it much safer for swimmers.
While some older pools may still have just one main drain, it's advisable for pool owners to consider upgrading to comply with current safety standards or stop using the drain. Adding a second main drain or installing a safety vacuum release system (SVRS) can significantly reduce the risk of entrapment and enhance overall pool safety.
Main drains are a critical component of inground swimming pools, but they also pose a potential safety risk. By understanding the importance of having multiple drains or other anti-entrapment devices, pool owners can take steps to enhance safety and prevent accidents.
