Protecting Your Investment Through the Cold

In Northern California, our winters might be mild, but they still pose a threat to your swimming pool. While your pool may not be getting much use right now, walking away from it until spring is a recipe for expensive repairs.

At Legendary Pools, we believe your "dream oasis" deserves year-round care. Whether you’re in Palo Alto or the surrounding areas, following a few proactive maintenance steps and ensuring your pool heater is functioning properly can avoid the "green pool" surprise and equipment failures that often greet neglected pools in March. Here is how to keep your pool in legendary shape this winter.

1. Maintain Consistent Water Levels

It is a common myth that evaporation stops when the sun goes away. In reality, dry winter air and wind can accelerate water loss.

  • The Risk: If your water level drops below the skimmer, your pump will suck in air, lose its prime, and potentially burn out the motor.
  • The Rule of Thumb: Check your water level every two weeks. Ensure it stays at the midpoint of your skimmer opening to keep the system running safely.

2. Invest in a Quality Pool Cover

Think of a pool cover as an insurance policy for your water quality.

  • The Benefits: A professional safety cover does more than keep out dead leaves; it acts as a barrier against evaporation and helps maintain more stable water temperatures.
  • Professional Installation: If your current cover is torn or or you don't have one, Legendary Pools offers a variety of high-performance safety covers. Our technicians provide professional installation to ensure a perfect, debris-tight fit.

3. Keep the Water Moving

Stagnant water is an invitation for algae blooms and mineral scaling.

  • Circulation is Key: We recommend running your filtration system for at least a few hours every day (or a minimum of a few hours a week) during the winter.
  • Freeze Prevention: This circulation is your best defense against water freezing inside your pipes. Moving water is much harder to freeze, protecting your plumbing from catastrophic bursts during a cold snap.

4. Regular Water Testing is Non-Negotiable

Chemical balance doesn't take a vacation. Even in cold water, pH and alkalinity can shift, leading to corrosive water that eats away at your pool plaster.

  • The Safe Zone: Continue to test your water regularly. If you aren't sure about your winter chemistry, you can bring a sample to Legendary Pools for a detailed professional analysis and adjustment.

5. Vigilance Against Winter Leaks

Winter temperature fluctuations cause pool shells and plumbing to expand and contract. This movement can create new leaks or worsen existing cracks.

  • What to Look For: Keep an eye out for unusual wet spots in your yard or water loss that exceeds 1/2 inch per week.
  • Expert Detection: We specialize in professional leak detection using advanced pressure and dye testing. We can pinpoint and repair issues before they become major structural disasters.

Start the Spring with a Splash, Not a Repair Bill

By staying proactive this winter, you ensure that your backyard paradise is ready the moment the first warm day of spring arrives. Whether you need a winter health check, leak detection, or a new safety cover, the team at Legendary Pools is here to help.
