Above Ground Pool Installation Mistakes

Read This Before You Install The Pool

Are you about to install an above ground pool and wondering how to avoid the most common above ground pool installation mistakes?  In my fifty years of installing above ground pools I have seen them all.  You see, when people make an above ground pool installation mistake, here in Arizona, they call me to fix it.

It is hard to know where to start, there are so many.  Not leveling the ground would be a good place to begin.  The most important part of installing an above ground pool is that it must be set on perfectly level ground.  When installations are attempted on unleveled ground the results are never good.

Attempting to install a pool on a base of sand is an installation mistake that is made a lot.  The sand is a cushion for the liner only, the frame needs to sit on firm, level ground.  If there is sand anywhere near the bottom rail when the wall is being installed it can become a real mess.  The rail fills up with sand and the wall will not go in the way it is supposed to.


 

pool wall blew down
An above ground pool installation mistake I see a lot is letting the sidewall stand without support.  New sidewalls start looking used real fast when they are allowed to blow over a few times.  Sidewalls left with no support, or held up with string or tape, will usually fall over a time or two.  Every time they fall over they get dented, scratched and creased.  If you build the pool frame as you install the wall it will never be left unsupported.  It is also helpful to plan your installation so that when the wall goes up you have enough time to finish with the liner installation.  The pool is only completely stable when it has water in it. This can also happen at liner changing time as did the one in the photo.

Attempting to install a used liner has been the downfall of many do-it-yourself pool installations.  Everything is going fine until that shrunk up used liner does not fit, things can go downhill fast at that point.  At this point walls can blow down, or be pulled down from a liner that is too small.  No matter how good the job was so far it can all be ruined quickly by trying to install a liner that will not fit.  Used liners are hard enough for us pros to deal with, they should never be used by a home owner. But if you really want to know I will tell you how I do it. Used Liner Installation  Do yourself, your pool and your family a favor, buy a new Pool Liner.  (#ad)

oval pool parts
Oval pools are an installation mistake waiting to happen.  The side braces can be very complicated and if they are not done correctly disaster can happen.  You need to seriously consider your building skills before starting this type of installation.  Be sure you have instructions and be sure they are followed.  We get called to finish oval pools all the time because they are that hard.  It is OK to say this might be over my head, let's hire a professional. If you feel up to the challenge read these pages first.

Oval Pool Installation Mistakes

 

nuts and bolts for pool wall
Another one I see a lot is not starting the wall behind an upright. This photo shows how not to do it and the next photo is the correct way. Doing this incorrectly can lead to bad things as you will see. Not building the entire pool before installing the liner makes this mistake go unnoticed at times.


 

starting the wall behind an upright
This is the correct way to start the wall. This insures the skimmer and return openings are not behind uprights, the only thing behind an upright are the nuts and bolts holding the wall together. They are not that great to look at anyway, why not hide them. The two photos below show what could happen when the wall starting place is not behind an upright. In the thousands of pools I have installed over the years I have seen one pool where starting in the middle of a footplate ended up with a skimmer opening behind an upright. We had to take the wall out and start between uprights, nothing else we could do, and I felt bad because it is just not a good look. The wall was made wrong, this should never have happened.

space between preformed pool cove
I see this one on occasion when doing liner installations. If you are using the pre-formed pool cove but them up tight and then duct tape over every joint. It is very possible for the liner to sink down into every opening, not a pretty picture. Butt them up and tape them, you will have a much better end result.


 

bottom rail gap
A few things can go wrong here. It has to do with what I call the bottom rail gap, meaning the little space between the bottom rail and the stop button. Some instructions are specific about this but most are not. To start with my bottom rails are connected using a tape measure from a center point so the pool will be perfectly round. The gap is set either with my best judgment or the instruction manual. Here is where this can go bad quickly. You unroll the wall and it is six inches short of meeting at the ends, and this does happen. So you go back a few rails and butt them up in the footplates. Now the wall fits but you have a pool that is not round and your top rails will not fit properly in this area. The proper way to fix this is to remove the wall, re-gap all the bottom rails, make sure it is round and start again. It's a real pain but worth your time to do it right. If I get to the end with only an inch or two off either way I can go back maybe a third of the pool and make some small adjustments but keeping it close to the same works.


 

unibead liner excess
Installing one of those uni-bead liners can be a problem also. You get to the end and this happens. Or maybe you don't have enough liner. In Arizona with a temperature over a hundred degrees it is easy to pull on the liner a little too much and end up like this. You take it all out and start over. Vinyl can be either pushed back or pulled forward depending on your needs. The important thing is to make your changes uniform around the entire pool. Just like the sidewall not fitting, don't try to adjust in a short area, take the time to do the whole pool.


 

pool inground backfilled
Let's talk about your above ground pool installation in the ground. How far can you sink it? My recommendation is always have the water level well above the backfill. The pool wall alone will not support the weight of the dirt, it's the water that does that. I see big problems here when it comes to liner changing time. When the pool is drained the chances of the wall caving in are great, causing major expensive problems. You are much better off with the pool at least a foot out of the ground, or six inches at the least. With six inches you can be sure your water level is above dirt level, as long as the pool is always full. With a foot out of the ground you have more leeway in regards to water height. Each to his own but this is not the way I would do it.


 

rocks around in ground above ground pool
One more thing when it comes to above ground pools sunk in the ground is the landscaping around it. This looks nice and is not a bad thing. The pool is out of the ground a bit so it is not going to cave in and will stay like this for many years, but at some point you will need to change the liner. Before you drain the pool pull all the rocks back away from it. The dirt will have packed solid but with any movement on the pool wall during the liner installation and those rocks will start getting in behind the wall. This can start an entire mess of rocks and dirt caving in the wall. Avoid that problem and move the rocks, they can be put back in when the new liner is installed and the pool full of water.


 

rusted pool wall on above ground pool
Not really installation related but we were talking about new liner installation time, right? If your pool ever has a leak, find it and fix it. Leaks can lead to big time wall rust. Dry rot around the top of the liner, the part above the water level, is inevitable and can cause this kind of thing from happening. When you see this starting it is time to replace the liner.

The photo above could lead to this. If you are doing a liner change and your pool wall looks like this take some time to make it pretty again. You can sand it, paint it and make it look like new again. You can even reinforce any areas that you feel are week or thin. Take your time and make it solid again. I have seen many pool walls last another ten years or more if treated right. Now is a good time to take care of it.


 

My personal favorite installation mistake is too many friends and too many beers.  The scene is always the same.  The yard is nothing but pool parts and beer cans everywhere.  The first hour is spent finding and sorting the pool parts and getting rid of the beer cans.  We can then start to undo, and redo, what took a group of men all weekend to accomplish.  Two people can easily build an above ground pool.  This is a case where the more is not always the merrier.

This page, Above Ground Pool Installation, shows you how two people can build a pool without any of these big time pool building mistakes.
