Now what!? Fixed the holes, pool collapsed!

Farmgirl - I presume your reply is meant toward my comment, just so you know, I did not say "AG pools DON'T come with...", I said - "usually used in IG pools - AG pools mainly use j hooks or overlap." primarily because it's the most common way of doing a vinyl lined IG pool, and the least common way of doing an AG pool. I would hazzard to guess less that 10% of all AG pools come with a beaded liner, 20% with j hook (this number is increasing fast) and the rest are overlap - primarily due to it's cost savings.

My J hook liner was also really easy to install, the nice thing with J hook and beaded is that your print is nice and square and everything is straight.

Yes, Matt,.....but again, i did not mean to be a pain. I just did not know that beaded liners were that rare in above ground pools. Thanks for sharing that info.

Farmgirl, you are by no means a pain. You were just making an observation. When beaded liners fit correctly you and Matt are both correct, they are very easy to install and very pretty. When they don't fit right, ouch.

I agree 100% with Matt's percentages. That's exactly what we see here in Arizona.

I sure wish we would here back from Newbie. It is so rare for this to happen in this way, I just have a lot of questions. Most of the time the liner will simply slip out of the coping, leaving the wall upright. I have seen this happen under the skimmer where the liner can't slip out, once in a while. I hate unsolved mysteries.

Correct me if i am wrong, but can't ANY liner slip out of place? Mine seems Ok, though perhaps not perfect. It is pretty great looking considering DH and I installed the pool ourselves, from the ground up, with very few written instructions to follow. We had NO experience, just made up our minds and did it! I had wanted a pool all my life, and he did all the ground prep for me. Fortunately, he works for a marine construction company, and could borrow all the equipment we needed for free, AND he knew how to use it!!! LOL! But liners age, and do not stay "stable" for their entire life span right? I mean, ground shifts, water shifts, temperature changes.......won't they all affect how the liner "behaves"??? I would think most liner problems would come with old age (ahem!) and shrinking when pool is dry. Am i on the right path here?

Farmgirl, congrats on your pool install, enjoy something you have wanted for so long. Yes, all types of liners can pull loose. Beaded liners are well known for coming out of the bead reciever. Special plastic inserts are made to keep them in place in touble areas. Because the bead reciever is also a strong retaining rod the liner will usually pull out of the bead, or tear just under the bead, before it brings the wall down. A j hook liner is held in place by a good retaining rod also. That might be a tough pull as to what would give first. Overlap liners usually pull free of the wall but some retaining rods have an extra tight grip and the walls will pull down.

The number one lesson learned. There is only one reason to drain a vinyl liner pool, if you are going to change the liner. All vinyl liners will shrink when left empty, even for a day. refilling could be a problem.

A very informative thread....sad, but informative. I just recently finished our AG and learned quite a bit, especially about temperature and vinyl. Because the pool face east/west, only 1/2 gets sun and I installed the liner in mid winter. I'll tell you this, "NEVER AGAIN!" It would not stretch and when I did get it to fit...barely, it started to buckle the sides. I waited 3 weeks for a day to exceed 70 degrees and what a difference several degrees made; it stretched like Saran Wrap and no issues what so ever. This was a J-Hook system.

I will ask this however: If for whatever odd reason a person needed to lower their AG water, how low would you say one can do this safely without running into a situation such as liner shrinkage?

Bob-i wish i could help you with this answer, but i know some of our pool veterans will.....i have never had my water level below that which we drain for winter closing. about 5 inches below the skimmer.
