Whether you are losing more than a quarter of an inch per day in a humid climate or one-half inch per day in a dry environment, you should check to see if your pool is leaking. Leaks can be caused by damage below the surface of the pool that cannot be seen easily. For example, a missing piece of fiberglass insulation could allow cold air into the pool area. The insulation would cause the temperature of the pool to drop each night, but without any other changes being made, it would be difficult to detect this problem from outside the pool.
Leaks can also be caused by problems with equipment such as heaters, filters, and skimmers. These devices are needed to maintain the quality of the water in your pool. If any of them are not working properly, they could allow contaminants into the pool that will eventually lead to water damage elsewhere in your home.
Leaky pools can lead to serious problems for both your pool and your house. Damaged pool walls and floors can result in wallbanging--when objects hit the side of the pool directly above a leak. The force of these collisions can cause serious damage to plaster, wood, and concrete. Over time, water may also find its way into areas of your home where it doesn't belong. This can cause structural damage or even cause houses to collapse due to excessive weighting.
Evaporation causes a 1/4-1/2 inch loss of water every day in most pools. This equates to 2–4 inches every week. For a typical-sized pool, evaporation will result in a loss of 25,000 to 50,000 gallons of water each year. The amount of water lost through evaporation depends on several factors such as temperature, humidity, and other sources of water loss.
Water that has evaporated can't be replaced so any measures that reduce evaporation would help maintain pool quality. The main cause of evaporation is the sun's heat, which dries out the surface of the water. Evaporative surfaces such as white sand or blue foam reduce the amount of water that is lost through evaporation. These additives cost more than plain old black sand but they are worth it if you want to keep your pool clean. There are also products available for sale at swim spa shops and online that claim to reduce evaporation. Some work better than others so try a few before you buy a new one for your pool.
Water that has evaporated can't be restored so make sure that you account for this loss when calculating how much to add to your pool. If you don't add enough water, then the area around the edge of the pool may become depleted of water due to evaporation. This could lead to problems with algae growth in an otherwise algaeclean pool.
How Fast Does It Evaporate? Pool water loss should be expected to range between 2 millimeters and 2 inches each week due to evaporation. Swimming pools can lose up to 1 meter of water through evaporation each year.
This is usually not a problem unless you live in an area that experiences excessive humidity. In this case, you will need to add more water to ensure the pool remains at its desired depth. If the water level drops too low, it could lead to problems with your pump.
Evaporation is caused by heat and sunlight. The faster these factors increase, the more water will be lost. Temperature influences how quickly water vaporizes. Warm temperatures cause water to evaporate more rapidly while cold temperatures cause it to move into ice crystals or gels. Sunlight also has an effect on water loss. More light means higher rates of evaporation.
Water evaporates from swimmable pools in two ways: transpiration and leakage. Transpiration is the loss of water through the plant life surrounding the pool. This is normal and to be expected. Leakage is when water escapes from around the edge of the pool - either through ground cracks or sewer lines for example.
The rate of water evaporation varies based on location, temperature, humidity, and wind, but an open swimming pool can lose up to 5 mm of water every day on average. A bucket test is the most accurate technique to measure how much water your pool loses due to evaporation. You should perform the test at least once a year and more often if necessary.
Water evaporates because it is a product of heat and air movement. The higher the temperature, the faster water will evaporate. So during hot periods, when it is 95 degrees outside, your pool will lose water faster than during cold periods when it is 50 degrees out. Heat also causes moisture in the air to change into water vapor, which is why it is important not to leave any containers full of water or other liquids outdoors during hot weather.
Swimming pools lose water through evaporation not only from the surface of the pool but also from within the water. As water evaporates, the amount of dissolved gases such as oxygen and nitrogen increases, which can cause pain for those with asthma or other respiratory problems. It is therefore recommended that swimmers take a break from diving every four hours to allow time for their lungs to re-inflate after going underwater.
Wind also plays a role in how fast your pool loses water. If you have windsock markers around your yard, you will know exactly how strong the wind is by how many times it spins.
