Although above ground pool liners tend to have a life of up to 10 years, there are occasions when it will need to be replaced. In addition to knowing what is required, being aware of the process necessary to replace will ensure that it lasts for another 10 years.

Step 1 – Preparation

Begin the process of replacing the above ground pool liner by undertaking the relevant preparations. Check the existing liner to determine what it is made from. Though many are constructed from vinyl, there may be occasions when other materials are used. It will also be necessary to ensure that you obtain a liner that is of the correct size. Without removing it, you should peruse the manual that came with the pool to determine what size is required. In addition, you should ensure that the conditions are suitable for the work. Undertake the work in fine weather when the temperature is above 75 degrees F, which will ensure that the liner can be properly manipulated without becoming damaged. Gather all the tools and equipment that you will need to complete the process.

Step 2 – Drain

Before you can change the above ground pool liners, you will need to drain it off all the water. This process can be undertaken with a submersible pump or with a water hose, which will allow you to siphon the water out.

Step 3 – Disassemble  

Once the water has been completely drained, you will be in a position to remove the above ground pool liner. There are likely to be rails holding it in place, which will need to be removed to access the liner. This is likely to be held in place with clips that you can simply remove by hand. Follow this by removing the rail at the top edge of the pool, where the liner is being held in place at this point. All of the clips and fasteners must be removed to enable you to remove the liner easily. Once the liner has been removed, it will be easier to measure to confirm the dimensions needed for the replacement.

Step 4 – Rectify

Without the above ground pool liners in place, you will be able to undertake any repair work required to the surface beneath the liner. In some instances, it may require nothing more than smoothing out with a trowel and, in other circumstances, you will need to add more sand or similar material.   

Step 5 – Replace

The replacement liner will need to be fitted in the same way that the old one was removed, ensuring that there is no air between the surface and the liner. Refit the clips and the metal band at the top edge of the pool to secure the liner in place. If necessary, use a vacuum during the process of refilling the pool with water to remove any air that might remain.
