    Replace your own In-ground pool liner and save thousands of dollars, joining thousands of other handy homeowners who replaced their own inground liner. 

    STEP ONE: Follow our easy to understand inground pool liner measurement instructions and online form. Fill-in the measures and your liner pattern choice, and hit submit! A helpful liner tech will review your measurements and follow-up with your in-ground pool liner price. 

    STEP TWO: Drain the pool completely, to a downhill location or storm drain. Remove all wall fitting and step screws and faceplates. Cut-up and roll-up the old liner. 

    STEP THREE: Prep the floor and walls. Clean off the walls, sand and paint any rusty spots. Fill-in any cracks or divots in the floor with our Palmetto Vermiculite

    STEP FOUR: Install the new liner. With 1-2 helpers, spread the liner over the pool and lock the liner bead into the track at the top of the wall. 

    STEP FIVE: Set-up the Cyclone liner vac, to draw out the air from behind the liner, sucking the liner tight against the walls and floor. Install main drain covers.

    STEP SIX: Fill the pool! Run the vacuum until water covers the shallow end floor by 3-6". Screw on step cover plates and continue to fill the pool until full. 

    STEP SEVEN: Install the skimmer and return faceplates and gaskets, along with the pool light ring and gaskets. Turn on the filter pump, and balance the water!

      Pool liner
      Liner was exactly what I thought. Solid, easy to install, and looks great. I used the bead and the remove of the extra J-Hook wad as simple as making a small cut and pulling the whole top off. Would recommend to anyone.

      Just ok
      Pool liner looks great however it was a little big . Had to be reworked after install in the chanell . Maybe pool walls had moved in a little or something. But overall good liner for the money. Yes I did have it put in by an installer .

      Great product
      Take your time and installing is easy. Makes pool walls so much softer

      Well Worth The Extra Investment
      Four cans of spray really was enough to go around the perimeter of my 15X30 Pool, with a permanent adhesion.

      A must
      Perfect way to keep the liner bead in place. I used some silicone spray lube. Sprayed the bead lock and the coping. Makes this a much easier install. I also used the handle end of a hammer to push the lock in. Looks nice!

      Exactly what we needed
      Purchased this recently for our above-ground pool. The liner is new, but the pool is old and we were having trouble getting the liner to stay in the track. This provided the perfect solution.

      Works Great!
      Installed this around my whole in-ground pool, because from time to time the liner would come down in some spots. The first time i called the company that installed my liner, they fixed it for free. The next summer, they wanted to charge me $200! I asked them how long they stand behind their installation, and they said just 1 season. When they fixed the first time, they put little but pieces of the insert just where needed.... when they originally installed, they did it in all corners and a ... read more few other spots... now i feel very confident that i have solved this problem for good. It takes some time to do the whole pool, but once done, it looks so much better as well!
