When and How to Drain Your Pool in Arizona

Plaster pools in Arizona typically need to be drained every 3 to 5 years. However, the exact frequency can depend on several factors, including:

Factors Influencing Draining Frequency:

  1. Total Dissolved Solids (TDS):
    • Over time, TDS levels in pool water can rise due to the accumulation of minerals, salts, and other dissolved substances. High TDS levels can affect water balance and make chemical treatments less effective.
    • Test TDS levels regularly and consider draining the pool when they exceed 1,500 ppm.
  2. Calcium Hardness:
    • Arizona's hard water can lead to an increase in calcium hardness over time, which can cause scaling on pool surfaces and equipment.
    • Drain the pool when calcium hardness levels exceed 400 ppm.
  3. Chemical Imbalances:
    • If maintaining proper water chemistry becomes increasingly difficult, it may be time to drain and refill the pool.
  4. Algae or Contamination:
    • Severe algae infestations or contamination from organic matter or chemicals may necessitate draining the pool to effectively clean and reset the water balance.
  5. Water Clarity and Quality:
    • If the water becomes consistently cloudy or difficult to clear despite regular maintenance, draining and refilling can help restore water quality.

Seasonal Considerations:

  • Avoid Extreme Temperatures: In Arizona, it’s best to drain the pool during the cooler months (spring or fall) to avoid damage to the pool structure from extreme heat.
  • Monsoon Season: Avoid draining during monsoon season to prevent issues with ground saturation and hydrostatic pressure, which can cause the pool to lift or crack.

Steps for Draining:

  1. Plan Ahead: Ensure the weather conditions are suitable and you have the necessary equipment.
  2. Coordinate with Local Regulations: Check with local authorities for any restrictions or guidelines on draining pool water.
  3. Proper Disposal: Direct the drained water to a suitable location, such as a sewer clean-out, and avoid draining onto streets or neighbors' property.

Regular Maintenance:

  • Regular testing and balancing of pool water can extend the time between draining. Use proper filtration, regular brushing, and vacuuming to maintain water quality.

By considering these factors and maintaining regular pool care, you can determine the best schedule for draining your plaster pool in Arizona. If you need help or have questions, give our Pool Shop pros a call at (602)996-8100.
