An above ground pool is useless without its liner. The pool liner is basically a large bag made of vinyl that is designed to hold water within the pool's frame. It is the most important part of above ground pools and has the potential to be the most frustrating. Liners must be handled carefully and installed properly to avoid damage to the vinyl. Our basic guidelines for liner installation will help you do it right, whether you're just setting up a new above ground pool or replacing an existing liner. Click for Above Ground Pools
If your liner is being installed on a new above ground pool, you should have completed creating the cove at this point. The cove is a wedge of sand or pre-formed foam that keeps the liner from slipping under the pool wall and also provides a protective layer between the liner and the metal frame of the pool. If you are replacing a liner in an existing pool, be sure to inspect your cove and build it back up if necessary. This is an important step that should not be overlooked.
Since the liner is the most delicate part of the pool, we recommend inspecting it first. Open the box containing your liner very carefully - do not use a sharp object. Unfold the liner and spread it out, making sure the ground is clear of anything that could puncture it. Check for any holes or tears and examine the seams to make sure they are properly sealed. This is very important as you do not want to discover a defect after you’ve filled the pool.
After your liner passes inspection, spread it out in the sun. The sun's heat will warm up the vinyl, making it more pliable and easier to work with. Refer to the manufacturer’s instructions regarding preparing the liner. Your owner’s manual should give you details about installing the liner, including punching out the skimmer and return holes. Remember, above ground pool liners are not meant to bear any of the weight of the water so they must rest on the ground in all areas. Properly installed, there should be no air space between the liner and the ground, and no downward pressure on the liner. How you hang the liner on the pool wall will depend on the style of liner (overlap, beaded, or j-hook) so refer to the instructions provided with your above ground pool and/or liner.
Air between the liner and the above ground pool wall can contribute to wrinkles. To decrease this, you can use a vacuum hose, inserting it through the skimmer hole in the pool wall behind the liner. Use masking tape and cardboard to seal any gaps around the skimmer hole and vacuum hose. Turn on the vacuum and gently adjust the liner while the vacuum is running. You can turn the vacuum off periodically if you reach any areas where the liner becomes difficult to adjust.
The vacuum can continue to run as you fill the pool but be sure to keep the hose above water level at all times. You can fill above ground pools with a common garden hose, or hire a water truck which is much faster. When the water is no more than 1 inch deep, check for levelness. If water runs to one side, pull back the liner and make the ground level. When level, continue to fill and adjust the liner.
