      Rated 4 out of 5 by from Liner came as advertised, easy to install except getting it unfolded in proper position was a challenge, not fault of supplier, just my inexperience. Pool looks good, holds water, couple wrinkles, but again my fault

      How can I find a leak in my liner?
      – Take some food coloring and go to where you think there might be a leak, if so the food coloring will be drawn to it.

      How many pieces of coping strips do I need?
      – Multiply pool size by 3.14, round it up and divide by 2, this equals number of pieces needed.

      What is the lowest temperature to install a liner?
      – 60 degrees for a beaded liner and 50 degrees for an overlap liner.

      What is the measurement on an overlap liner?
      – An overlap measures 53.5” and is used for both a 48” and 52” wall.

      Can I stretch a liner to fit a larger size pool?
      – No, you have to match up your pool size with the same size liner. We do have custom above ground liners to accommodate any size above ground pool.

      What if my pool is larger than 48” or 52” deep?
      – We stock expandable pool liners that can accommodate a pool that dishes out in the center 60” or 72” deep. If your pool goes from shallow to deep you would need to fill out a 6-01 measuring form.


      Installation Instructions

      RECOMMENDED ITEMS NEEDED FOR INSTALLTION

      • 2” gray duct tape with non-asphalted adhesive
      • screwdriver
      • garden hose
      • sharp nail or ice pick
      • industrial vacuum or household vacuum (filter bag removed)
      • tamping tool
      • masking tape
      • utility knife

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

      PREPARATION OF POOL BOTTOM

      1. Spread a 2” layer of brick sand over the entire pool foundation area inside the base rails. Use a rake to make the brick sand flat and smooth. Tamp sand to help reduce footprints. In place of brick sand, you can use “Soft Step” Floor Padding. Cut the sheets to fit and join them with duct tape along the whole length of each seam.
      2. With the brick sand, make a curved cove about 4” high and 4” wide all around the bottom of the pool wall on the inside. Pack firmly into shape. Pool Cove can also be used.

      LINER INSTALLATION

      1. Place the closed liner carton in the center of the pool.
      2. Open the carton. Do NOT use anything sharp to open the carton.
      3. Unfold the liner and spread it out in the sun to warm up.
      4. Inspect all seams and surfaces for holes.
      5. Spread out liner. The curved seam should be centered on the cove at the base of the wall. The other seams will form straight lines across the bottom of the pool. If seams appear to have flaps, check to see if correct side is up.
      6. Smooth out all wrinkles in the bottom.
      7. If you have a beaded liner, fasten the liner in place by lifting the sides of the liner and inserting the beaded edge into the liner retainer on the top edge. If you do not have a beaded liner, lift the sides of the liner and drape them over the top of the pool wall. Fasten liner to the top of the wall with plastic coping. Let the liner hang slack for now. Do NOT pull liner tight.
      8. Start filling the pool with water. As the pool fills, work out the wrinkles and smooth the liner to the wall. Remove the plastic coping around the top edge of the wall one piece at a time and adjust the liner. Keep smoothing out the wrinkles.
      9. Do not install faceplates, inlets, light fixtures, etc. until water reaches 3” below each opening. Premature installation might result in the liner tearing away from the opening due to stretching as the water level increases.
      10. Proceed filling pool until water reaches desired level.

      OPTIONAL STEP TO ELIMINATE WRINKLES

      1. To remove air from behind the liner, which prevents wrinkles, insert a vacuum cleaner hose through the skimmer hole in the pool wall behind the liner. To minimize vacuum loss, seal the opening around the hose and the water inlet using cardboard and masking tape.
      2. Turn vacuum cleaner on. While vacuum is running, you should be adjusting the liner with short tugs to eliminate wrinkles. If you have trouble shifting the liner into position, shut vacuum off for a few minutes. You should then be able to adjust the troubled area before continuing with the vacuum.
      3. Start filling the pool with water. The vacuum cleaner should continue to run until water level nears the top. Make sure to keep vacuum cleaner hose above the water level at all times.
