Steps On Leveling the Above Ground Pool Already Up

To complete the work, you need the following tools:

  • Hammer
  • Grovels
  • Garden hose
  • Shovel
  • Wheelbarrow

Tip: It is best to work slowly and persistently to make sure that your surface will get even as much as you can. By doing this, you will achieve a more durable and stable ground pool.

Having this in mind, below are the steps on how you should properly level an already-up pool.

Identify Where the Problem Originated

One of the possible causes of having an uneven pool is due to some external factors. So, before you start leveling your pool, it is best to determine the primary cause of the problem first. Some of the causes may include a washout from under the pool. The legs could be not on the center or a rodent problem.

Drain The Pool Halfway

Now that you know the root of the problem, you can start the work of releveling the above-ground pool. Draining the pool is the first step you need to do—good thing you don’t need to drain all the pool water. Removing around 50% of the water pool is enough to make it easier to handle since it will become lighter.

Remove the Leveling Blocks

After draining the pool, the next step is to identify the side that lowered and remove the blocks underneath that you use in leveling. The blocks are responsible for keeping the pool level. So, if you have an unbalanced pool, you have to hold up the blocks a little.

Prying Up the Wall Level

With the use of the shovel, pry up the wall from the very bottom of the leveling blocks. Continue prying up until you achieve the preferred level.

Placing the Blocks Back On

After achieving the preferred level, you can place the blocks back on. If upon returning the blocks, you notice that it is not yet on the level you want, take out the blocks again and pry even more. After prying more, place the blocks back again and check.

Perform This For All Sides

Repeat all steps for all the sides.

Add More Soil

After completing the process on all the pool sides, you need to add soil to cover the blocks. Add enough soil to make the ground stable. Then, add some water to harden the soil.

Fill the Pool with Water

Fill the pool with water up to the desired level. Then observe the pool and check if it is still lopsided.

How Level the Pool Should Be?

An expert on installing a pool will tell you that they can do everything to keep your facility as level as possible. It is easy to obtain when installing an above-ground pool.

In spite of having all the knowledge and the right tools, it can be a hard task to get it level. The right level of the pool is within ⅛ inches. A pool with the right level is safer and will last for many years. It is thus vital that your already up above ground pool is leveled.

The Causes of Unleveled Pool

There are lots of things that can make your best above ground pool uneven. Some of them are discussed below:

Pool Set Up on Uneven Ground

Placing the pool on the unleveled ground will put a lot of pressure on the lower side. You can either leave the pool on that position and hope it will not get damaged, but it might worsen in the future. The best thing to do is to level the ground without removing the pool down.

Variation from Leg to Leg

If you don’t solve this issue, there could be more pressure on one leg. But, you can correct this issue without taking the ground pool down. You can use a bubble level to check the level of the legs if your pool is about 3 inches full. Then recheck it after filling it with water.

Washout Under the Pool

For the sloped backyard, water can run under the pool and wash the soil out. If this is the case, reset the pool by making sure that the ground is even out.


It is best to keep in mind that the bottom track is level and not the surface within your pool. Your pool is safer and will look great if you can get that track level, and it will last for several years.
