LA Pool Plumbing: Sizing & Circulation Requirements Explained

Effective pool plumbing isn’t just a pipe dream. If your pool plumbing isn’t up to par, you’re likely facing high energy bills, frequent repairs, and potential safety hazards.

What is the Virginia Graeme Baker Act?

Pool_Plumbing_Sizes_Circulation-BLOG 3The Virginia Graeme Baker Pool and Spa Safety Act (VGBA) is a federal law enacted to eliminate the hazard of swimming pool and spa entrapment. Signed into law on December 19, 2007, this act directs the Consumer Product Safety Commission to protect the public from risks associated with pool drains, which are classified as consumer products under the ANSI/APSP/ICC-16, 2017 safety standard.

Compliance with the VGBA is crucial for pool owners to ensure their pools meet federal safety standards, preventing accidents and ensuring peace of mind. This regulation impacts pool plumbing, requiring specific standards to be met.

Who sets the plumbing and circulation requirements in the first place?

Pool plumbing must adhere to industry standards set by key organizations, such as the Pool and Hot Tub Alliance and the International Code Council (ICC).

These standards vary based on the pool's water volume, ensuring consistent filtration needs. Knowing these entities' roles is key for builders, designers, and pool owners to assure compliance with proper plumbing standards.

Why Specialized Knowledge in Pool Plumbing Matters

Pool plumbing is a specialized field that goes beyond regular mechanical engineering. While mechanical engineers can handle various system calculations, they might not be familiar with specific pool industry regulations and health department requirements.

Involving a licensed plumber with expertise in pipe sizing, circulation systems, and equipment specifications is crucial for the success of your pool project. Their specialized knowledge ensures that all aspects of your pool plumbing meet industry standards and safety regulations.

TURNOVER RATE

To ensure that pool water stays clean and safe, the circulation system must complete a full cycle of circulating all the water through the pump and filter within a specific time frame or turnover rate.

According to industry standards, the circulation system should be designed to circulate the entire pool water at least once every 12 hours. The system size should match the manufacturer's specified maximum flow rate of the filter, ensuring efficient turnover with a clean filter.

DOE REGULATIONS

Per DOE Regulations, pumps are now rated based on power, not just horsepower. Properly sizing pool plumbing is essential for long-term planning and potential pump replacements. Finding an exact match might be tough if the pump breaks or needs replacing, leading to a mismatch with the existing plumbing.

A smart solution is installing a variable-speed pump to control water flow and meet requirements, even if the pump's capacity exceeds the original design. Proper sizing of pool plumbing ensures safety and efficiency.

To better understand this concept, think about when you're washing your car and the water hose can't reach it. You put your finger over the hose to increase the water pressure and make it reach the car. Plumbing systems operate in a similar way. If the pipes are too narrow for the water flow, it moves too quickly, which can be hazardous.

For instance, imagine swimming in a pool with undersized pipes. As you turn around, the forceful water flow strikes and hurts your eye. Preventable injuries like these can range in severity, but they stem from wrong plumbing sizes. 

Code Compliance and Safety

Pool regulations prioritize safety. Having a dual drain is not enough; the entire plumbing system must meet specific requirements to prevent entrapment hazards and ensure pool safety. Plumbing codes set limits on water velocity and pressure to prevent accidents and ensure good filtration. 

To guarantee a safe swimming environment, it's essential to have a proper plumbing design with controlled velocity and well-sized drains.

CONSULTING A PLUMBER DURING CONSTRUCTION PLANS:

It is very important to have a plumber involved in the early stages of pool construction. They plan the number of pipes, their sizes, and where to put them.

Working with experts like plumbers, mechanical engineers, and experienced pool contractors helps to communicate plumbing needs effectively, including specific pipe sizes, equipment room capacity, and filtration considerations. This personal approach ensures a smooth construction process that perfectly matches the pool's size and specifications.

THE ROLE OF PLUMBING IN DESIGN

Pool_Plumbing_Sizes_Circulation-BLOGAlthough design usually happens before pool construction, involving an experienced individual who understands pool construction is essential. 

This expert will ensure that the design is both visually appealing and functional. By addressing potential issues early on, they can avoid problems like water splattering or inadequate containment, resulting in a well-designed pool that meets your expectations.
