What is the evaporation rate of a pool?
Usually, pools lose water at specific rates depending on the weather conditions and pool chemicals. However, the standard rate of evaporation is 20mm per day. Of course, the amount varies based on many factors like climatic conditions and pool size.
How much water evaporates in a swimming pool?
There’s a large range regarding how quickly pool water evaporates—it can be as little as two millimeters to as much as two inches per week. Climate is the biggest factor that determines how quickly pool water evaporates. However, there are other factors that you have some control over.
How much water evaporates from a pool every day?
about a quarter of an inchIf pool owners or maintenance workers are constantly filling up the pool, there may be a leak. 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.
How much should a pool evaporate in 24 hours?
Even though these circumstances have a lot to do water loss, they should not have a drastic effect on your water level. Most pools experience between 3mm - 7mm of water loss each day, depending on where you live.
Why does my pool water evaporate so fast?
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. Heated pools on cool nights experience evaporation more rapidly.
How do I know if my pool is leaking or evaporating?
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.
How often should you need to add water to 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.

How much water will evaporate from a pool in the winter?
about a quarter-inchAn uncovered pool will lose water in the winter to evaporation in the same way it does during the summer.

What happens to a pool when it evaporates?
Evaporation is when liquid turns into a gas or vapor. This process happens to almost any body of water under the right conditions, including swimming pools. This means, as a pool owner, you lose a measurable amount of pool water every day through evaporation. Several thousands of gallons of water per year for an average residential pool, in fact.
Why does water evaporate faster in a pool?
Temperature. Heat increases the rate of evaporation (yes, even at night), so you should expect your water to evaporate faster if you live in a warm climate, and slower if you live in a cold climate. Humidity. Air can only hold a certain amount of liquid vapour, so, unlike temperature, the more humid the air is around your pool, ...

How to prevent water from evaporating in a pool?
Here are some “evaporation prevention” measures you can take: Use a regular pool cover. A pool cover or even a safety pool cover will do a great job blocking water evaporation since water particles can’t escape through solid material. Use a solar pool cover (or blanket).
How to fix a leak in a pool?

So, testing for the evaporation rate requires the pool owner to use a practical procedure. What you have to do is take a portion of your pool water and fill it in a bucket of medium size.
Is it bad to lose pool water?
Losing pool water through evaporation is not good. So, ensure that your pool is not directly exposed to the sun. Additionally, create windbreakers around the area. Think of incorporating an automatic pool cover that protects the pool when it is not in use. In fact, pool covers are essential features that are compulsory in several states.
Can windbreakers cause evaporation?
There are many possible causes, and they can cause harm to the pool. Fortunately, pool owners can prevent high evaporation rates through pool covers. Also, they can install windbreakers around the surrounding area. Ultimately, they should make sure their pools experience average or fewer evaporation rates.
Pool Water Evaporation and Temperature
Water can and will evaporate over a broad range of temperatures—meaning, even cold water that hasn’t frozen. Any time that the water molecules at the surface of your pool are moving quickly enough, they’ll split from the other molecules and transform from a liquid into a gas.
How Much Water Loss in a Pool is Normal?
First, you’ll need to know how much water your pool holds. This will help you monitor water loss, whether that’s occurring strictly through pool evaporation or also because of a leak.
