Don't let an uneven pool ruin your summer fun!

Assessing Your Pool's Level

Before you start leveling your in-ground pool, you need to determine exactly how unlevel it is and in which areas. Neglecting a thorough assessment can lead to incorrect adjustments and further problems.

Tools You'll Need:

Level: A long level (at least 4 feet) is essential for accurate measurements. A laser level offers even greater precision.
Measuring Tape: For taking precise measurements of depth and distances.
Marker: To mark areas that need adjustment.
Notepad and Pen: Keep track of your measurements and observations.

Steps to Assess Pool Level:

Check the Water Line: Carefully examine the waterline around the entire perimeter of your pool. A consistently uneven waterline is a clear indication of an unlevel pool.
Multiple Measurements: Take multiple level measurements at various points around the pool, both along the walls and the bottom. Record these meticulously.
Identify Low Points: Note the points where the waterline is significantly lower than the average. These are your target areas for leveling.
Photograph Evidence: Pictures provide a helpful visual record of the pool's current condition.

Methods for Leveling a Pool with Water

There are several ways to level an in-ground pool while it's filled with water. The best method depends on the severity of the unlevelness and the type of pool you have.

Method 1: Adjusting the Pool's Structure (For Minor Unlevelness)

This method works best for pools with only minor deviations from level. It involves carefully adjusting the pool's structure itself to bring it back into alignment.

Tools and Materials:

Jacks (hydraulic or screw): These are used to lift and support sections of the pool wall. The size and number will depend on the pool's size and construction.
Wood Cribbing or Concrete Blocks: Provide a stable base for the jacks.
Gravel or Sand: Used to fill gaps or level the base beneath the pool.

Steps:

Locate Low Points: Precisely determine the points where the pool is significantly lower.
Position Jacks: Strategically place jacks under the low sections of the pool wall, supporting them with cribbing or blocks.
Lift and Level: Carefully raise the low sections using the jacks until the pool is level, checking with your level frequently. This is a slow process; avoid jerky movements.
Fill Gaps: If there's a significant gap, fill it with gravel or sand to provide a solid foundation. Remove excess material as needed.
Monitor for Settling: After leveling, closely observe for any settling. If this happens, repeat the process as necessary.

Method 2: Adding or Removing Water (For Slight Unlevelness)

For very minor discrepancies, strategically adding or removing water can help achieve a more even waterline. This is a less labor-intensive method.

Steps:

Identify Low Spots: Determine the sections where the waterline is the lowest.
Selective Water Addition/Removal: Carefully add water to low spots using a hose, and remove water from high spots with a submersible pump.
Monitor Waterline: Constantly monitor the waterline after each addition or removal of water to ensure even distribution.
Repeat as Needed: Repeat the process until a relatively even waterline is achieved.

This method is only effective for very minor unleveling.

When to Call a Professional

If your pool is significantly unlevel, or if you're uncomfortable attempting the above methods, it's best to call a professional pool contractor. Attempting to correct major structural issues yourself could damage your pool.

A professional has the expertise, equipment, and experience to properly diagnose and correct leveling problems. They can also advise on any underlying issues causing the unlevelness.

Preventing Future Leveling Issues

Regular inspection and maintenance of your pool's structure can prevent future leveling problems.

This includes:

Annual Inspections: Inspect the pool's structure for any signs of shifting or settling.
Proper Drainage: Ensure that the area around the pool drains properly to prevent water buildup.
Soil Compaction: Maintain good soil compaction around the pool to prevent settling.
Addressing Cracks Promptly: Any cracks in the pool structure should be repaired immediately to prevent further damage.

By following these steps and seeking professional help when needed, you can keep your pool level and enjoy it for many years to come. Remember safety first! Always prioritize your safety and the structural integrity of your pool.
