If your pool lost water overnight and it is more than the quarter-inch due to evaporation, you probably have a leak. Evaporation accounts for a minor amount of water lost each day. Losing a half-inch or more overnight indicates a problem.
The differential that occurs between the pool water temperature and the air temperature on late summer nights causes water to evaporate at an accelerated rate. In some cases you might see a water level difference of 1-3 inches overnight. Depending on the size of your pool, that can be over 500 gallons of water loss!
Losing more than ½” of pool water per day indicates you likely have a leak in your pool's structure or your pool pump system. You should call your pool service for a thorough leak inspection. You might not be able to keep up with refilling your pool at this point.
Typically, pools lose water for one of two reasons: Evaporation or a leak. Evaporation naturally occurs in any body of water, but it may increase under certain conditions, such as hot, humid weather. Leaks, however, indicate a bigger problem that a professional may need to address.
If the water loss is larger when the pump is running, the likely culprit is the underground return line. However, a leak in the return or jet fitting will also leak at a greater rate when the pump is on (there is pressure in the system).
If the water went down a similar amount in the pool as well as the bucket, then you lost water due to evaporation. If it went down more in the skimmer and not much at all in the bucket then you have a pool leaking.
Look closely at the filter, pump, heater, and pipe valves, which is where leaks often tend to occur. If you have a vinyl pool liner, look for tears or separations around the fittings, lights, steps, and corners.
On average, swimming pools lose about a quarter of an inch of water each day, yet variations in wind intensity, humidity and sunlight can drastically change water loss rates. Some of the strongest and most intense wind in the country can be found in mountainous regions.
How often should I have to fill my pool? This will vary depending upon several factors including: weather, if the pool is covered or not, bather load, and if it is heated or not. With pools that are covered, a good rule of thumb is that they should not have to be refilled more often than once every 2 weeks.
As a result, most evaporation actually occurs at night. This might seem counter-intuitive, but the reason is that at night the pool water is relatively warm, but the air temperature has dropped. What is this? Therefore, the difference between the air and water temperatures is greater – thus, more evaporation occurs.
As the temperature of your pool's water gets colder, the differential pressure between the water and the air increases. This speeds up the rate of evaporation. In addition, lack of humidity and wintertime dry air can also increase evaporation rates. The humid air during the summer keeps more water in your pool.
Lower Your Water Temperature
As the temperatures drop, the warm water evaporates even faster. In warm water, molecules turn into mist, which evaporates quickly. This process accelerates when the temperature of the pool water is higher than the air's temperature. Cold water is more resistant to evaporation.
Most pools experience between 3mm - 7mm of water loss each day, depending on where you live.
Pumps and motor problems can cause a swimming pool leak. General wear and tear on the pool surface can cause leaks. Broken plumbing beneath the pool deck can saturate the ground. Loose fittings on railings, tiles and other accessories lead to leaks.
Evaporation occurs whenever you expose wind or air to the surface of your pool. So in short, this applies to every pool, all the time. Water molecules rise to the surface, form into a vapor and eventually get released into the air.
Quick answer: You can expect to lose between 2 mm to 2 inches of water in your pool per week due to evaporation, depending on the various factors we'll get into in this article.
The warm temperatures during the day heat your pool up, then the cooler temperatures at night cause the water to evaporate. This happens throughout the evening, until the sun comes out to warm the pool water again. Humidity: When humidity levels are high, evaporation is low.
The rate of water evaporation varies depending upon location, temperature, humidity and wind, but it isn't uncommon for an uncovered swimming pool to lose 5mm of water per day on average. The most accurate way to determine how much water your pool loses through evaporation is with a bucket test.
Generally, pool water needs to be replaced once every five to seven years. This should be done during mild weather so that your pool surface is not at risk from strong sunlight and heat. Your pool maintenance company can recommend when it is time to drain your pool.
But did you know there's an easy way to reuse the water that's already in the pool? All you have to do is recycle it! Meet reverse osmosis — the best way to purify your swimming pool water. It works by pushing the existing water through semipermeable membranes that hold off any impurities, particles, and buildup.
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
Every pool must turn over at least once a day, so most pool pumps should run approximately 8 hours a day. But here's the thing: you don't have to run your pool pump consecutively. You can choose to run it for three hours in the morning before you leave for work and another 5 hours in the evening.
Chlorinated water, such as that from a pool is not suitable for watering plants. High levels of chlorine are toxic to plants.
