Site Preparation

As you embark on the site preparation phase of your above-ground pool installation, it’s essential to pay close attention to detail. Proper site preparation not only ensures a stable foundation but also contributes to the longevity and safety of your pool. Let’s dive deeper into each step:
1. Clear the Area
Thorough Debris Removal: Start by thoroughly clearing the chosen location of any debris, rocks, or vegetation. Imagine creating a clean canvas for your pool to rest upon. Remove all obstacles that could hinder the pool’s stability or damage the liner.
Pro Tip: If manual labor isn’t your thing, consider renting a small excavator or hiring a landscaping service for efficient debris removal, especially if the area is significantly overgrown or contains large rocks.
2. Choose the Center Point
Determining the Center: For round pools, pinpoint the center of your pool’s future location. Pound a sturdy stake into the ground, ensuring it’s secure and level. Attach a string to the stake, with its length equal to half the pool’s diameter. As you walk in a circle around the stake, mark the ground with spray paint to outline where the pool will sit. This will give you a guide on where to clear the sod and debris.
Adding Extra Space: To provide ample room for assembly, maintenance, and safety, add an additional 6 to 12 inches beyond the marked outline. This extra space ensures you have enough room to maneuver around the pool.
3. Remove Sod
Thorough Sod Removal: Prior to installing your pool, it’s crucial to remove the existing sod or grass from the designated area. This step serves several purposes:
- Prevents Weeds and Roots: Eliminating grass, weeds, and their underlying root systems minimizes the risk of vegetation growing under your pool, which can damage the liner over time.
- Promotes Level Ground: Sod removal ensures the pool’s base rests evenly on the soil, preventing lumps or unevenness that could affect the pool’s stability.
Tools for Sod Removal: To make the task easier, you can use either a shovel or a sod-cutter. Ensure that you remove the sod and grass down to the bare soil.
4. Level the Ground
Ensuring a Level Surface: Achieving a level surface is a critical aspect of site preparation. Use a builder’s level or a laser level to assess the evenness of the ground. Pay close attention to this step, as any discrepancies can lead to an unstable pool. Use a 10-foot long 2×4 and drill a vertical hole through one end. Put a 43-inch fencing spike through it on one end and into the center of your pool site.

Attach a cord to the other end and tape a carpenter’s level to the top of it. Drag the 2/4 around in circles while watching the level, in order to level out your spot. Add leveling sand as necessary.

Adjustment as Necessary: If you notice areas of unevenness or slopes during your level assessment, take the time to adjust the ground. You can achieve this by adding or removing soil as needed. Tamp the soil down firmly to create a stable base. Put a weight on the 2×4 in order to hold it down, if necessary.

5. Create a Base
Cushioned Foundation: Lay down a suitable pool base material, such as sand or foam pads, to provide a cushioned surface for the pool liner. This critical layer not only protects the liner from potential damage but also ensures a comfortable and safe swimming environment.
Long-Term Consideration: For those planning to keep their above-ground pool for an extended period, consider more permanent base options, such as pouring a concrete slab or laying down patio bricks. These provide exceptional stability and longevity to your pool’s foundation.
6. Install Ground Cloth
Additional Layer of Protection: To further safeguard your pool liner, place a ground cloth or pool floor padding on top of the base material. This extra layer acts as an additional buffer, reducing the risk of abrasions or punctures to the liner.
Pool Assembly
With your site well-prepared and the groundwork laid, it’s time for the exciting phase of assembling your above-ground pool. This is where the dream of your personal aquatic oasis begins to take shape. Having a few friends by your side can make the process smoother, especially when dealing with the pool frame components, which can sometimes be a bit unwieldy.

1. Lay the Liner in the Sun
Preparation is Key: Before you start assembling the pool, lay the pool liner in direct sunlight for a short period. This helps the liner become more pliable and easier to work with during installation.

Smooth Out Wrinkles: While the liner is sunbathing, inspect it for any existing wrinkles or creases. If possible, smooth them out to ensure a wrinkle-free fit when you install it inside the pool frame.
Position the Liner: Once it is warmed up, lay the liner at the center of your site. Position the holes for the filter pump at the right location. This may require rotating the pool liner until the filter pump inlet and exit holes are pointed toward the side where you want the filter pump to sit.
2. Assemble the Top Rail and Liner
The Framework Takes Shape: Begin the assembly by connecting the top rail components. The top rail forms the upper edge of the pool and provides support for the liner.

Attach the Liner: As the top rail takes shape, slide the supports through the corresponding loops in the pool liner.

Pro Tip: Enlist the help of your friends to hold the frame and liner in place as you attach the top rail. Their assistance ensures the liner remains properly positioned during this critical step.

3. Install the Support Legs
Adding Structural Integrity: Now, it’s time to install the support legs. Connect the legs to the top rail and secure them in place.
Uniform Spacing: Ensure that the support legs are evenly spaced around the pool’s perimeter. This uniformity helps distribute the weight of the water evenly.

4. Place the Legs on a Sturdy Base
Setting a Solid Foundation: Before you proceed, make sure the legs have a sturdy base to rest on. This is vital for the pool’s overall stability. We used 5″ x 5″ pieces of decking material under each foot to help distribute the weight and make sure that the legs didn’t sink.

Solid Ground: The ground should be level and well-compacted beneath each support leg. Use a builder’s level to confirm that the legs are resting on a flat and stable surface.
Pro Tip: For added support and longevity, consider placing concrete pavers or patio blocks beneath each support leg. This prevents settling and helps maintain a level pool.
5. Install the Filter System
Strategic Positioning: Place the pump and filter system in a location near the pool that is both accessible and stable, but not in the way of eager swimmers, usually this means rotating the pool so that the pump is at the “back.” Ensure it is level and securely mounted.
Plumbing and Electrical Connections: Carefully connect the plumbing from the pool to the pump and filter system, following the provided instructions. If electricity is required, adhere to electrical safety guidelines during installation and ensure proper grounding.

Pro Tip: To maximize energy efficiency and maintain water quality, consider adding a timer to your pump system. Regularly clean and maintain the filter to ensure efficient water circulation and filtration.

Filling with Water
With your above-ground pool structure assembled, it’s time to bring it to life by filling it with water. This phase of the installation process requires some patience and attention to detail. Here’s how to go about it:
1. Water Source
Connecting the Hose: Begin by connecting a garden hose to your water source. Ensure that the hose is long enough to reach your pool comfortably.
The Waiting Game: Be prepared for a bit of patience, especially if you have a larger pool. Filling an above-ground pool can take some time, and the duration depends on several factors, including your water source’s water pressure.
Estimating Fill Time: To estimate the fill time, you can use a simple calculation. The average garden hose provides a flow rate of approximately 12 gallons per minute. Use our Pool Volume Calculator to calculate the number of gallons your pool will hold, then divide by 720 to get the number of hours it will take to fill your pool.
For example, a round pool 18ft in diameter and 4 ft deep holds around 7,500 gallons of water, and So, for a 7,500-gallon pool, it may take approximately 625 minutes, or just over 10 hours, to fill it completely.
Pro Tip: Consider purchasing water from a reliable source. Pool water companies exist that will bring a tanker truck to your home and fill your pool with chlorinated water in a matter of minutes!

2. Monitor Water Level
Keeping It Even: As the pool fills, keep a vigilant eye on the water level. The fact that the filling process takes so long can make it easy to forget or neglect. Make sure the hose is secured and won’t fall out of the pool while no one is watching.
Smooth out the Wrinkles: It can be almost impossible to create a flat surface in the liner without any water in it. Fill the pool to about 2-3 inches deep, then get inside and smooth the floor liner to remove any wrinkles. The small amount of water will keep the liner smooth and in-place.

Pro Tip: Once the pool is full of water it will be nearly impossible to smooth out wrinkles in the floor. Smooth the wrinkles before the pool is completely full.
Adjust the Support Legs: When the water is about 1 foot deep, go around the outside of the pool and adjust the position of the support legs. Make sure the legs are straight, not crooked, and pull them out slightly, as the weight of the water will naturally force them outward as the pool fills with water. Once the pool is full, it will be almost impossible to adjust the position of the legs or the support pieces under the feet.

Continue filling the pool until it is full of water, to about 6 inches below the blue/brown line on the inside of the pool.

First Running the Pump
Congratulations, you’re almost there! It’s time to start up the pump and get your pool ready for swimming:
1. Prime the Pump
Ensuring Proper Circulation: Follow the manufacturer’s instructions carefully to prime the pump. Priming involves filling the pump and filter system with water to ensure proper water circulation.

Proper Priming Steps: Typically, priming includes the following steps:
- Open the pump’s air relief valve, or loosen the filter basket cover, to release any trapped air.
- Ensure all valves are set to the correct positions for circulation (open).

- Turn on the pump and allow it to run until you see a steady flow of water from the return jets.

2. Turn on the Pump
Initiating Filtration: With the pump primed and ready, it’s time to switch on the pump and filter system. This marks the beginning of the pool’s water circulation and filtration.
Initial Run Duration: Allow the pump and filter system to run for several hours during the initial cycle. This period helps filter out any impurities or debris that may have entered the pool during the filling process.
Pro Tip: If you have a sand filter, be sure to run a “Backwash” before allowing the filter pump to pump water into your pool. Why? The first time you run a sand filter, it will shoot sand into your pool! Run a Backwash and Rinse step to ensure you keep your pool free from loose sand.
