Installing an Above Ground Swimming Pool’s Overlap Liner

Installing an Above Ground Swimming Pool's Overlap LinerReady to jump into your refreshing above ground pool, only to realize that your liner is in desperate need of replacement? Never fear! Follow these steps and you’ll be back to making a splash in no time!

The Prep Work
• There are a few things you need to do before you get down to the replacement phase. Firstly, you’ll want to measure your pool. You’ll want to measure the length and width before shopping for a new liner to ensure that you purchase the right size.
• Once you’ve purchase the new liner and drained the pool, you need to get the old pool liner out. With a knife, box cutter, or sturdy pair of scissors, cut the liner about 1.5 – 2.5 inches below the top edge of the pool. Don’t worry – we’ll get rid of this scrap later.
• Once the old liner is out, do a quick checkup on the ground of the pool area. Level out low or high spots that may have developed and ensure that any rocks or debris is removed. Looks good? Alright, let’s get to the installation!

The Installation
• Carefully remove your new liner from the box and check that it is free from flaws and that it is the correct size.
• Alright, take off your shoes and let’s get down to business! Get the new liner (and yourself) inside of the above ground pool frame. Unroll it and line the seam at the bottom of the liner with the edges of the pool. Regardless of the shape of your pool, line up the seams of the liner with the pool edge as evenly as you can. Thoroughly smooth the floor of the liner.
• Starting at the wall joint, take off three of the pool’s top rails and copings. You can also pull out and pitch the little strip from the old liner that we left in earlier. Before you start attaching the new liner, keep in mind that it will be very loose during this phase so you’ll need to take care that you don’t tear any areas. Pull up the new liner and attach it to the frame with the copings to hold it in place. You can also use plastic clips, wooden clothes pins, or anything that won’t damage the liner if you’d like to reinstall all of the copings at the end. Continue around the perimeter of the pool. It is easiest if you skip a rail once in a while to avoid stretching the new liner and ending up with an excessive amount of liner at the end. Once you reach the end, go back and remove the skipped rails until all of your pool railings have been removed and the new liner is completely in place. Carefully smooth out any large wrinkles.

The Refill – Phase 1
• Slowly, begin refilling the pool. Carefully stretch out any wrinkles or folds on the pool floor as it fills. Stop refilling when the water has reached 5 to 7 inches in depth. Now you are ready to finish up with the liner!
• Smooth the liner up from the bottom around the entire pool. You will probably need to stretch, tighten, and adjust to remove extra liner as you go around. Just remember to be careful not to tear your liner as you do these readjustments. When everything looks nice and tight, you can replace all of the top rails around the entire pool.

The Refill – Phase 2

• OK – turn the water back on and continue filling your pool. Each time that you reach an area where the liner needs to have an opening cut out (such as a skimmer, filter, light, return, etc.) Stop the water a little ways below the area and install the fixture. Do not cut the liner from these spots until the fixture is completely reinstalled! If the fixture, such as the return, can’t be reattached without cutting the liner, cut it extremely carefully. If they aren’t the perfect size, you’ll have leaks and there’s NO FIXING A MISTAKE. When everything is reattached, and the liner has been removed from inside the fixture areas, you are ready to continue refilling the pool! Fill that baby up! Carefully check for leaks as the pool refills, especially around all of the fixtures and make any little adjustments needed.

The Fun

• You don’t need any instructions for this!
