The Las Vegas summer climate

When summer arrives in Las Vegas, pool owners often find themselves checking the water level more frequently and wondering whether the water is still properly balanced. The National Weather Service’s 1991 to 2020 climate normals show why summer maintenance deserves attention. July has an average high of 104.5 degrees Fahrenheit and an average low of 82 degrees. About 78 days each year reach 100 degrees or warmer, and about 47 nights stay at 80 degrees or warmer.

With long stretches of hot weather, regular visits give a technician a chance to check the water level, test the chemistry and look over the equipment. A pool can appear fine while its readings tell a different story, so testing should remain part of the routine rather than something reserved for visible problems.

Evaporation in the heat

Water loss is one of the practical issues of owning a pool in Southern Nevada. The Southern Nevada Water Authority estimates that an average in-ground pool loses 48.6 gallons per square foot per year through evaporation. For a typical 470 square foot pool, that can amount to as much as 22,842 gallons annually. A pool cover cuts evaporation by about 90 percent.

When water needs topping up, the local supply is worth keeping in mind. The Las Vegas Valley Water District describes valley tap water as very hard, with 280 parts per million of total hardness, or 16 grains per gallon, and 75 parts per million of calcium. The minerals come from the Colorado River through Lake Mead. Topping up with hard water raises calcium over time, contributing to scale at the tile line, in heaters and on salt cells.

Maintaining chlorine and stabilizer

Clear water is not a substitute for checking the chemistry. The Centers for Disease Control and Prevention recommends keeping pH between 7.0 and 7.8, with free chlorine at least 1 part per million in pools, or at least 2 parts per million when cyanuric acid is used.

Cyanuric acid, also known as stabilizer, can build up when tablets are used. The CDC notes that high cyanuric acid makes chlorine work more slowly. Lowering an elevated level requires a partial drain, so testing helps identify when the water needs more than routine chemical additions. When a pool needs draining, the Las Vegas Valley Water District and Southern Nevada Water Authority require the water to go into the sanitary sewer, usually through the home’s sewer clean-out, never into the street or a storm drain.

Equipment wear and hard water

Summer is also a useful time to pay attention to equipment condition. Hard water leaves calcium scale in heaters and on salt cells, as well as along the tile line. InterNACHI and the U.S. Department of Energy report that pumps and filters commonly last around 10 years, heaters around 8 to 11 years, and salt cells around 3 to 7 years, depending on run time and water balance. These are typical lifespans, not a timetable that automatically means equipment needs replacing.

For pumps, federal efficiency standards for new pool filter pumps have applied since July 19, 2021. In practice, this means variable speed pumps for most residential pools. A repair or replacement decision should take account of the equipment’s condition, parts availability and repeated failures, rather than age alone.

How Kingfisher Pool & Spa helps

Kingfisher’s weekly maintenance visits include testing free chlorine, pH and total alkalinity, with cyanuric acid and calcium hardness checked monthly. Salt is also tested on salt pools. The water level is checked on Full Care and Full Care Plus plans, and routine chemicals are added as the readings call for them.

After each weekly visit, we email a report with water readings, chemicals added, tasks completed, technician notes, equipment observations and a pool photo. If testing or an equipment inspection points to additional work, Kingfisher provides a written estimate before that work begins. Homeowners can then review the findings and the proposed next step.
