How to Level an Above Ground Pool with Water in It

Nothing matches the cool refreshment of getting into the best above ground pool during the hot days. However, this refreshment is only possible if your pool is installed correctly, level, and nice.

An above ground swimming pool needs to be placed on a level surface or it might end up having an unwanted shallow end. In addition to being unsightly, an uneven pool is shaky. 

Also, you will be risking the safety of both the bystanders and swimmers in case it collapses due to the uneven nature. This is why you need to take your time and level your above ground swimming pool.

What Makes a Pool to Be Uneven?

One thing that might make your pool to look uneven is the development of wrinkles in its liner. Another one is if the pool is misshapen or its uprights aren’t vertical. 

Your pool might also be leaking or the skimmer or the return fitting might not be secure making the surface wet and sinking the pool. Lastly, DIYer can install the pool on an uneven surface without noticing it. 

All these reasons will make your pool to be uneven and should be corrected as soon as possible. However, the biggest sign of a poorly installed pool is if it is “off level”. 

How Level Should Your Pool Be?

Professionals go a lot to ensure that your above ground pool is as level as possible. But you should note that there is no precise level that you should install your pool, making it a tall order to get a 100% level pool.

Despite all the knowledge, quality equipment, and desire to level a pool, pool professionals are pretty satisfied with a pool that is an eighth of an inch off level. For oval shapes, a quarter of an inch off level is accepted.

If you are a DIY person, pool manuals often recommend you to level your facility within an inch off level. This won’t cause any structural problem but you can easily notice that your pool is “off level” when you view the waterline.

How to Level You Existing Pool

Usually completely “off level” swimming pools should be taken down, leveled, and then installed again. If you do that, you will need to buy a new liner as it is not advisable to reuse the old one.

If your pool is slightly off than it should be, you can easily change this without taking down, but it is hard. A majority of professional pool installers even cannot do this.

What do you do?

  • Drain your pool (but not all the water).
  • Remove the leveling blocks (those under the uprights on the low end of the uneven pool). 
  • Use a shovel to pry up every wall from the base connectors to the right level and return the blocks.
  •  Do these for all low end of your pool. 
  • Pack and add earth under all the places that you have raised the wall. 
  • Refill your swimming pool.

You shouldn’t try to lower the high part of your pool. 


Now you can easily level an above ground pool with water. Good luck!
