How to Level an Above Ground Pool with Water in it

The best time to level your above-ground swimming pool is before you set up your pool.

That said, there are times when you’ll want to level your pool with water in it.

The most straightforward way to level your pool is to drain the water and level the ground. But you may not want to unnecessarily drain all your pool water if you believe you can resolve the issue without wasting all your pool water.

To help you best tackle this problem, I will share several tips that you can use to level a pool with water in it.

Let’s get started.

Steps to level your above ground pool with water

Before you start the leveling process, it’d serve you well to put ratchet straps around the legs of your above-ground pool. This will help ensure that your pool legs don’t slide or crumble as you level your pool.

1. Partially drain water

The first step is to drain your pool water partially. You will have to physically lift your above-ground pool during the leveling process, so draining a little bit of water will help reduce workload.

The amount of water you’ll want to drain depends on the water capacity of your pool. As a general rule of thumb, I recommend draining your pool water until the pool is about half-full.

If your above-ground pool has a large water capacity, you might want to drain a bit more water.

2. Take out leveling blocks and replace them

You now want to take out leveling blocks from the lower side of your pool that you placed beneath the slabs when you first set up your pool.

Next, use your shovel to dig under the slabs and press it down to lift them up.

Alternatively, you can also use floor jacks along with a 2 by 4 to elevate the lower side of your pool. Make sure there’s sufficient space between the ground and your pool bottom so you can slide in your pavers.

If you plan to manually lift up the pool, you’ll need to get someone to help you replace the leveling blocks while you are lifting up the slabs with your shovel. It’s also a good idea to use a hammer to get the blocks under the slabs.

Go ahead and completely replace all of the leveling blocks on the lower side of your pool.

3. Use soil to fill up the hole

Lastly, there’s likely a hole on the side where you lifted up your above-ground pool. You’ll want to fill that area up with soil.

When should you level your above-ground pool?

Less than an inch

If your pool level is off by an inch or less, it’s usually not a huge problem. This slight unevenness will likely cause your pool water to splash out more frequently, which is a bit wasteful.

But you generally don’t have to worry about your above-ground pool experiencing any serious issue with such a minimal unevenness.

More than a few inches

Things start to get a little more problematic when your pool level is off by more than a couple of inches. When the water level is significantly uneven, it starts to put a lot of strain on one side of your pool.

The more water pressure that your pool wall has to ensure, the more like it is to falter.

If your pool wall has to bear a significant amount of water pressure, it’s just a matter of time before it collapses. So it’s important you promptly level your above-ground pool when there’s a significant degree of unevenness in your pool.

Why should you level your pool?

There are a couple of reasons why you’d want to ensure your swimming pool is leveled properly.

First, it’s just not visually appealing to look at a lopsided pool. An uneven-looking pool will ruin the visual aesthetic of your backyard.

Second, an uneven above-ground pool can hamper the ability of the filter to work properly. This is important since you don’t want to be swimming in a pool full of bacteria and viruses.


As said earlier, the best time to level your above-ground pool is before you set up your pool. But if you’re determined to level your pool water without draining the entire pool, you’ll want to take a more strategic approach.

If the level is off by an inch or less, then it’s often not a big deal, and you likely don’t have to worry about any severe damage.

But if the level is off by more than a few inches, you will want to promptly fix the issue at hand, so you can prevent any potential damage.

I hope this article provided you with a clear direction on how to level an above ground pool with water in it.
