Keep the Pool Cool

By Joshua Clinton, CPO Advisory Council

Servicing pools in climates with extreme heat can be very challenging. As we approach the peak summer season in the Northern Hemisphere, it's important to know ways to mitigate the impacts of high heat on your pools.

Let’s look at Phoenix, Arizona, where average summer temperatures are 110°F or higher.

1. Dehydration

According to the CDC, people who work outdoors—especially in severely hot climates—are at an increased risk of dehydration.

What can we do?

Drink plenty of fluids especially those that contain electrolytes. Avoid drinking alcohol or drinks with large amounts of sugar. Wear a brimmed hat and lightweight clothing. Take frequent breaks to get out of the sun

2. Evaporation

The average evaporation rate in Phoenix is approximately 6 feet per year! The average pool evaporates its entire volume of water in a year!

What can we do?
One of the best things you can do to prevent or slow down evaporation is to install a pool cover.

3. Chemical Instability/Algae Blooms

Heat and UV rays cause pool chemicals to break down faster, which affects the water quality and can lead to issues like algae growth and cloudy water.

What can we do?

It is essential to the health of your pool to monitor your water chemistry and balance it accordingly. Besides this, brushing your pool routinely plays a huge role in algae prevention.

4. Equipment Maintenance

High temperatures can also break down the protective insulation in pool pump motors. UV rays can cause degradation on PVC plumbing.

What can we do?

Painting pipes and creating a shady environment for pool equipment will be incredibly helpful to protect the pool equipment. Totally Enclosed Fan Cooled (TEFC) motors also add an extra layer of protection to increase the life of your pump.

5. Maintaining a cool water temperature

Warm water can be less than refreshing and promotes algae growth if your chemistry levels are not in balance.

What can we do?

You can run your pool pump at night when temperatures are lower. You can also add shade structures such as pergolas or umbrellas that can reduce the UV exposure. One thing you will see on most pools in Phoenix is aerators that will aid in cooling the surface of the water.
