Inground Pool Liner Installation Instructions


  1. Remove old In-ground Pool liner.
  2. Remove all debris from inside pool and around pool deck.
  3. Standing pool water must be removed from the bottom of non-porous pool shells.
  4. Inspect pool shell for irregularities. Make any repairs if necessary.
  5. Using duct tape, cover all seams and sharp edges of pool shell. If pool walls are rusty or splintered, use protective pool wall foam.
  6. If the pool bottom is sand, it should be dampened, leveled and tamped. For best results, pool liner should be installed while sand is still damp.
  7. Proper installation requires at least four people.
  8. Pool liner should not be installed in temperatures under 70 degrees F.


  1. Placement of the pool liner should be done from the deck of the pool to avoid making marks on the pool bottom and possibly puncturing the pool liner.
  2. Place the pool liner in the middle of the pool deck on the deep end of the pool.
  3. Remove the pool liner from the carton and unfold across the width of the deep end.
  4. The pool liner should now be positioned so the top section marked “WADER” is exposed.
  5. Pull top section marker “WADER” toward shallow end.
  6. Lower the pool liner into the pool, taking care that the top corners do not fall into the pool shell.
  7. Corners should be tight against the sidewall. Verify that the hopper portion is in the deep end and the shallow portion is in the shallow end. Also make sure the pool liner is right side up.
  8. Locate the exact position of the corners on the beaded pool liner. Each corner is marked on the underside of the pool liner sidewall near the top directly above the bottom corner. Both the top and bottom corner must be positioned in the middle of the shell corner.
  9. Insert the pool liner beading into the locking channel corner pieces. You must insert the beading with finger pressure in order to prevent pool liner damage. Do not use tools or sharp objects to perform this operation.
  10. After corners are locked into position, move to the center of either pool sidewall or endwall. Start inserting the bead into the receiving channel working toward the corner.
  11. Once complete, double check all corners to see that they remained in the proper position.
  12. Continue by gently easing the pool liner so that the bottom fits exactly into the shell. The bottom should be flat without any excessive folds. Complete as much of this operation as possible from the deck, as it is possible to indent footprints into the floor. Never wear shoes in pool.
  13. In order to hold the pool liner in position during the next step, place water tubes in the shallow end at the point where the sidewalls intersect the bottom. Also place water tubes around the bottom rise of steps if your pool is so equipped. This will assure a professional fit and reduce the possibility of liner damage due to over stretch.
  14. To remove air from behind the pool liner, which prevents wrinkles, loosen 6” of beading form the locking channel within 12” from any corner. Insert a vacuum cleaner hose behind the pool liner until it reaches the bottom of the sidewall. To minimize vacuum loss, seal the opening around the hose. This may be done by using either masking tape or wet rags. Any accessible openings, such as pool skimmers or water inlets on new excavations, can be sealed off with cardboard and masking tape to increase the efficiency of the vacuum.
  15. Turn the vacuum cleaner on. It will normally take 20 to 30 minutes before the suction will completely draw the pool liner into place. While the vacuum is running, you should be adjusting the pool liner with short tugs to eliminate wrinkles. If you have trouble shifting the pool liner into position, shut the vacuum off for a few minutes. You should then be able to adjust the troubled area before continuing with the vacuum. Do not start filling with water until the pool liner is in perfect position.
  16. Once the pool liner is positioned properly, begin adding water with a garden hose while the vacuum is still running. Water should be turned on gently in the deep end first. Once the pool water begins to accumulate in the deep end, the water pressure can be increased.
  17. After 8”-12” of water have been added to the deep end, it is necessary to install the main drain faceplate. With your hands pressing on the pool liner at the main drain opening, locate the screw holes and puncture them with a sharp nail or ice pick. Install the top gasket of the  face-plate making sure that the faceplate is screwed tightly in place. Do not cut out the opening until plumbing lines have been installed. C
  18. Continue filling the pool and working out wrinkles. The vacuum cleaner should also continue to run until water level nears the top. Make sure to keep vacuum cleaner hose above the water level at all times.
  19. Remove water tubes when water level reaches 6” in the shallow end.
  20. Do not install face plates, inlets, light fixtures, etc. until water reaches 3” below the opening. Premature installation might result in the pool liner tearing away from the opening due to stretching as the water level increases.
  21. Proceed filling pool until water reaches desired level.

WARNING: Pool liner should be stored at room temperature for at least 72 hours prior to installation.

Recommended Items Needed for Installation
Items needed include: screwdriver, sharp nail or ice pick, water tubes, tamping tool, staple gun (if installing an overlap liner), shop vacuum, utility knife, 2” gray duct tape with non-asphaltic adhesive, masking tape or rags, garden hose, broom, possibly gaskets and gasket cement.
