    Well, today I have to review an above ground 25 mil liner pool which is 4 feet in height. But they want to put it inground. The manufacturer provide aluminum wall supports and panels. The installer is saying that they have of course done this before and the only change they have ever made is that the panels are required to be preservatively treated. The aluminum frame is left exposed on outside like a skeleton and backfilled against the plywood attached to inside of skeleton. Liner is then applied and filled with water.

    Anybody seen this before? I did find a youtube video on one but that guy actually built a timber retaining wall and left space between the wall and pool.

    We did a permit 2 years ago for someone installing one from this company (not an advertisement) - International Swimming Pools, Inc.

    It looked a lot like an above ground pool, steel frame and vinyl liner, set below grade and back-filled.

    rktect 1,

    Can you obtain the manufacturer' installation requirements for this critter? They may or may not

    allow it to be installed below grade.

    It will in fact lose its warranty from the manufacturer if buried. But homeowner was sold on idea to do this so that if they ever move they can take the pool with them. ??????

    And they can't take the pool with them if installed above ground?

    rktect 1,

    I too would be concerned with the loads of the soils surrounding the
    pool skeleton when / if installed below grade. If they (the homeowners)
    are headstrong on installing it below grade, does the AHJ have any
    policies in place to address this (can you say .."variance"?), or to do
    as you have indicated in Post # 1, ..have a space between the pool
    skeleton and the surrounding soils? The soils ARE going to move
    and settle against the skeleton at some point. Not sure engineering
    this ($$$) is going to satisfy the homeowners. They're already buying
    a Cheapo product, voiding any warranties by installing it below grade,
    and now adding engineering costs to the equation to add more money
    to this "proposed" debacle. Really?

    Do the homeowners have that much money to waste? :eek:
    As we all know though, ..people with money do not worry about such
    trivialities as shifting soils, and structural loads.

    Does the manufacturer' instructions allow this? Doesn't matter with or without
    a warranty.

    Some people do have a penchant for tempting fate. Eh?

    I would say its the service that needs to go underground now, not the pool

    Hi guys, I need an advice. Has anyone of you already heard about swim spas? I was thinking about installing one of them in the backyard. Any personal experience?

    Thanks in advance!

    Dealt with one in a resort where they also used it as a hot tub. Too hot to use for swimming and took to long to cool it down or heat it up. The swim jets were not adjustable for stronger and weaker swimmers. They gave up with the swimming and just use it as a hot tub.

    But that was 20 years ago. There may be improvements now.

    In this way when you place them in the ground, they can collapse from the heaviness of the earth, yet just when they are unfilled.

    Swim spas are a big thing for sale at The Pomona Fairgrounds, they run ads on TV all the time. Installed in ground but due to depth are they bound by fencing requirements?

    If the pool is a listed "above ground (onground) pool", I don't think listing of the pool allows burial at any depth. However, I am vaguely familiar with liner pools that are intended to be installed in a hole. Again, back to the manufacturer to see how they intend for the pool to be installed. If the manufacturer will not stand behind it, then you know it shouldn't be done. And by the way, fiberglass shell pools can't be emptied either! They have to fill those as they are backflilled.

    I'm glad they call them "Onground Pools" now. I never did see a pool floating above the ground.
    I see a lot of onground pools partly buried where there are slopes in the back yard. It' probably better than fill to level it. Also I have reads a few manufacturers installment manuals and never seen anything saying not to do do it. If it voids the warranty that is not my problem. The warranty is usually just for short time anyway and I don't think anything would happen to a partly buried pool in that amount of time.

    Many decades ago we depressed the center of our 48" high Doughboy pool 18", leaving a 36" level ring inside and sloped from there to the center.
    Used it for years, great fun. Ran and high jumped the side wall to enter the pool. Liner held up great.
