When the liner is totally adjusted (and if an overlap liner, the plastic coping is secured), push the primary stabilizer rail (also called high rails) over the plastic coping or pool wall in order that it suits snugly (beginning on the wall bolts is normally a good suggestion).

PRO TIP: Go away one finish of the stabilizer barely raised in order that the subsequent stabilizer can interlock. Relying in your pool’s model, you’ll have alternating stabilizer rail sizes.

Preserve the vacuum on till the water reaches just under the Store Vac hose on the wall. Flip off the vac, take off any tape you added, and take away the Store Vac hose. Proceed filling the pool, stopping to regulate the liner if any wrinkles develop. It would be best to modify these as you go, because the liner can’t be shifted after the skimmer and return holes have been lower.

Don’t set up faceplates, inlets, lighting fixtures, and so on. till the water reaches 3” under the particular opening.
