A familiar sight each season for many vinyl-liner pool owners is sags or gaps at the track that holds the liner in place. Constant fluctuations in temperature over the winter can cause the vinyl to stretch and pop out at certain spots—most often at corners or where there is plastic trim in a concrete deck that meets with the pool coping. In many cases, the vinyl can be pulled up and snapped back into place in just a few minutes. Dive in!
Steps
-
Boil a kettle of water. It may take several kettles, depending on the size of your liner. [1] X Research source- Slowly pour the hot water directly on the sagging vinyl below the top edge. Use a kettle or can with a long spout, such as a watering can.
- Do not pour onto the very top edge of the vinyl, but just below the top, because you next have to grasp that top edge.
- Pour slowly back and forth across the vinyl.
-
Pull the vinyl up. As the hot water softens the vinyl, grasp the top edge and firmly pull the vinyl up and above the track, so that when released it remains just above the track. [2] X Research source
- It may take several cans of water before you can pull the entire edge up sufficiently.
- It may also be necessary to lower the water level 6 inches (15.2 cm) or so to increase the amount of vinyl you can stretch.
- This task is easier if one person pulls up while the other pours the hot water. But one person can do the job alone if necessary.

Re-track the vinyl. Starting on one end, firmly twist the top edge horizontally and push it into the metal track. [3] X Research source- The top underside of the vinyl has a V shaped groove which should slip into a similar V groove in the top metal track.
- You should feel the edge of vinyl slip into the groove, which is supposed to keep it in place.
-
Hold the vinyl in place. Use a large, wooden paint stirrer to help push and hold the vinyl in the track as you pull the vinyl up and into place. [4] X Research source- Be very careful not to tear through the vinyl.
- For longer splits use wooden clothes-pegs broken in half and placed along the split every few inches.
-
Finish up. Upon completion of stretching and tucking, get several special short (1/4 to 1/2 inch long) plastic jamming pieces from your pool supply store, and jam them into place between the top of the plastic and the underside of the metal pool rim. This will help ensure the plastic liner stays in place. [5] X Research source
-
Use an extension cord and a hair dryer or heat gun. [6] X Research source- Heat an area of the liner to stretch by holding the blow dryer a couple of inches from the surface and at an angle. Keep the dryer moving so you don't burn the liner. You don't need to superheat the liner—just get it warm enough to make it pliable.

Note: Be careful that no one is in the pool while using electrical appliances, as dropping it in the water could be deadly.

Tips
- Always start in the center of the area to be put back into the track and then work to halfway around each side, until the liner is completely back in place.Thanks
- It helps if you can have someone else pour on the boiling water, while you pull the liner into the track.Thanks
Warnings
- Most pool professionals would not consider using a heat gun or hair dryer to heat a liner. Boiling water on the liner is not dangerous if you are careful and does not pose any risk to the liner. Any heating element has the ability to create a red-hot ember that could potentially land on the liner and melt a hole in it.Thanks
- Blow dryer method: electricity and water are not friends - if you drop the dryer, do not reach for it, unplug the extension cord from the wall.Thanks
- Remember that you are using scalding hot water! Be careful where you pour it.Thanks

About This Article
Vinyl swimming pool liners can often sag or slip out of position, but luckily you have several simple ways to repair them. Try pouring boiling water onto the affected area of vinyl, making sure to leave 1 to 2 inches at the top so you can grab hold of it. Alternatively, you can heat an area of the vinyl by blow drying it from about 2 inches away. Once the heat from the boiling water or hair dryer has softened the vinyl, pull it up from the top to stretch it out. Fit it back into the metal trap around the top of your pool, which is designed to hold the vinyl in place. If you're concerned about the vinyl coming loose again, add several plastic jamming pieces, which you can buy at a pool supply store. For tips on how to put a patch on your vinyl, read on!
