Why Does Pool Water Level Drop

If you own a pool, you know that it is as much responsibility and work, as it is a luxury and amenity. Apart from skimming it every day to keep the water clean, you also need to make sure that the water chemistry is just right.

However, there is another thing you need to pay attention to which is not mentioned as often as these previous two points. Water levels can fluctuate a lot over the year, and you need to make sure that there is enough water in your pool, too.

Pool experts at Kona Labs share some ways you can figure out why your pool water levels vary so much.


Well, the simplest solution, and the one which is responsible for the loss of water in the majority of a pool, is simple evaporation.

Your pool is a large surface of water left out in the open in the sun. If the day is warm as much as 2’’ can be lost every week just to evaporation. This is, of course, a high estimate, but if this is the amount of water you lose every week, you might be just experiencing evaporation.

Various Features Cause Water Loss

Do you have a water slide? Or an infinity pool, or a waterfall built in your pool? If the answer is yes, the amount of water you might lose each week increases, as these features cause a lot more water to be lost, either to evaporation or spilling.

Other Factors That Contribute to Water Loss through Evaporation

There are some factors which can contribute to increased water evaporation and make it reach the 2 inches we mentioned as the peak value.

The first factor is exposure. That is, what percentage of your pool is directly exposed to the sun, and for how long. Additionally, the temperature difference between night and day can have a serious impact on the amount of water you lose to evaporation.

Finally, the air humidity is probably the most important factor which will determine how much water will evaporate. If the air is humid, it is already saturated with water, and the evaporation rate will be lower than in drier climates.

Leak in the Pool

A more serious matter is if your pool is losing more water than is normal. In that case, you might be facing a leak.

Depending on the complexity of your pool and the rate of water loss, you may be able to locate and fix the leak yourself, or you might have to call in professionals who have pool leak tools which help locate leaks much more effectively and quickly.

Why Do Pool Leaks Occur?

Did you have a custom pool made by a company such as SoCal Custom Pools & Spas? Do you have a water slide? Or an infinity pool, or a waterfall built in your pool?

There are different reasons why your pool may leak, but all of them need to be taken seriously and repaired as soon as possible to avoid any further damage to your pool and other property.

The ground where your pool is located might have settled, causing a leak, or it could be something as simple as a faulty fitting or a seal.

How to Find the Leak

Start with the plumbing around your pool. If you spot any wet spots or actual leaks, you may have located your problem.

However, if the plumbing is sound, and you are losing water at a constant rate, it is more likely that you are experiencing a crack in the shell or the vinyl cover of the pool. If the crack is small, you can use a caulking agent like putty to seal it. Alternatively, call your pool maintenance company to send someone to help you.

Ensuring that your water levels are constant goes far beyond saving money on the water bill. It is also important because you are protecting the structural integrity of your pool and its components.
