Thread: Level Issues

  1. Back To Top    #1

    Level Issues

    I just installed a 24' round pool, and I leveled the ground per the instructions with a 2X4 and level. Florida is flat ground, but it was a lot of work. I worked for weeks to get it right before we installed it, and moved a ton of dirt. Well it is now filled, and I notice the water is higher in certain points, based on the line on the liner. Not sure if that is a good measuring stick or not. But it is about 1" or less i would say, maybe 1.5". It is like one of the 16 pillars is lower than the others, and not a whole side. I don't see any bulges, the skimmer works fine and it is barely noticable. But being the perfectionist my wife is, she mentions it, and i notice it too. So I would like to know:

    -How do you measure "out of level"?
    -What is a good range of out of level...from 0" to a max of X" is OK?
    -If so, how can you fix it without draining the pool? Can you jack up one side and shim it with something?

    Any thoughts and comments are much appreciated. Thanks!

    Re: Level Issues

    You say it's just one let a little lower but the pool, in general is level? I wouldn't touch it. You're good. Can you post a pic?

    That being said, that one leg can be raised if you want to do it.

    Re: Level Issues

    After 3 years mine is about 3/4 inch out of level (it was within 1/4 when I filled the pool). I measure this by measuring the distance between my top rail and the water level at each leg.

    How much is too much is hard to define and depends if it is getting worse or not. For installs, 1 inch out of level is considered the limit of acceptability, but that does not necessarily mean the pool will fall over. 1.5 inches makes me uncomfortable, but if the wall is straight in then I would leave it. At 2 inches I would definitely consider draining and fixing. I am not aware of fixing a permanent agp without draining.

    Re: Level Issues

    In this case his "out of level" issue is a little different. From what I understand, his pool is level, but at one point one leg is lower (like a dip in that spot - correct me if I'm wrong). There are posts here (one for sure with pictures) where the owner jacked up the rails and shimmed under the leg without issue. But if his level issue is what I'm interpreting it to be, I would leave it alone.

    Re: Level Issues

    I think that thread was on a intex style and not a permanent agp?

    Re: Level Issues

    Well pictures aren't coming out that great, but I measured the water line to each pillar. Here is what they were. I numbered from each side of the ladder.

    1 - 4"
    2 - 4"
    3 - 4"
    4 - 3.75"
    5 - 3.75"
    6 - 3"
    7 - 3.25"
    8 - 3"
    9 - 2.99" It was very close to 3, but not quite
    10 - 3.75"
    11 - 3.75"
    12 - 4"
    13 - 4"
    14 - 3.5"
    15 - 3.25"
    16 - 3.75"

    Seems the patio block stage under each pillar was not quite exact. Being the stats nerd I am, the results are:


    Results:
    Total Numbers: 16
    Mean (Average): 3.5775
    Standard deviation: 0.39594

    The data set indicates that the average is 3.5775 +/- 0.40 inches. Two standard deviations is over 95% confidence, so 3.5775 +/- 0.80 or 2.775 to 4.3775.

    So in other words, none of my measurements are statistically significant enough to be outside of the 95% confidence interval. And my variability for 95% confidence is less than an inch. I think i am good....hopefully, lol.

    Personally I'd leave it, keep an eye on it over the years, I suspect you'll be fine.
