- DON'T BUY THE LIE!!!!! Find out WHY fiberglass pools don't just pop out of the ground. This is physics 101 as it applies to in ground swimming pools. Don't buy the lie propagated by vinyl pool installers that they pop out of the ground. Think about it and make your own decision.
See a concrete pool pop at • concretepoolpopping
Basically your first experiment failed so you switched to unrealistic poolception mode
We have a fiberglass pool and yes it did pop out of the ground, the whole length of the pool on one side. the pool is a san juan luxor grand and the pool was just drained to just below the jets and the lights to ensure no water was in the lines for the winter. pool been in the ground about 9 years and this spring was the first year. So they do pop up and we have pictures and bills to prove it. The key is to ensure that the individual that comes in to install the pool, goes the extra mile and ensure that the work and the material around the pool is done right. Problem is you don't find out if done right until you have a problem which is years later.
what material was backfilled with ur pool? around the pool
You're talking utter nonsense. If your contractor has to 'go the extra mile' just to give you what you're paying for, you should never have employed them.
It's like saying all fibre glass pools pop out of the ground. You probably didn't maintain it properly
Thanks for your comment. You obviously had more water on the outside of the pool than IN the pool. Im sorry that happened to you. The point here is that if there is water in the pool and that water matches the water around the pool the pool will not float. Not enough buoyancy is created to lift it. You can demonstrate the same thing in your kitchen sink. Place a casserole bowl in the sink. Fill it. Fill the sink to the same level. It will not float.
If you are a pool professional I am sure you are familiar with the bucket test. The bucket is placed on the top step with the same water as the pool. It doesnt float off. MORE water around the vessel, bucket, boat, or pool - YES there is buoyancy. The myth is that fiberglass pools pop out because they are fiberglass. That is certainly not that case.
so drain the pool.. and repost
love to see what happens when you drain the pool . Some how or some time it has to crack and or need repainting .
for this to be a valid "scale", you'd have to shrink the molecules. buoyancy is a net effect, plus the outer container gives way first, thus no pushing up
A more effective demonstration would be to drain the pool model and keep the ground water level up. Then, you could show people why you should never drain a pool without expert supervision (as the model pool will float). The real issue arises when someone inadvertently drains their pool when the water table is high. If the pool is fiberglass or concrete, it will likely move and float. If it is a liner pool, the liner will float and move but the pool structure will not be affected. All situations would require repair but the liner repair would be in the hundreds of dollars and not tens of thousands like a fiberglass or concrete pool.
as long as u keep water in the fiberglass pool nothing will ever happen
So what would happen if you lowered the water level in the pool?
Boat
Why didn't you actually drain it? I mean, your "experiment" wasn't at all to scale. To be so, you would have to have about another three feet of gravel under the pool, but you still could have drained it to see what happens.
Boats are made of fiberglass and they float just fine. Gunite pools will float if the underground water pressure is greater than the weight of the pool.Your demonstration is flawed.
Just had one pop out of the ground. Want to see the pics?
If you wanted to build a skyscraper, would you use fiberglass, vinyl, or concrete? Just because you can build a pool with all three materials doesn't make them equal.
What if you need to paint the fibreglass pool because the coat has worn
I love your idea and your video. Great way to show hydrostatic pressure, but I would say that pools do need to be emptied out about 5 to 7 years because the water no longer holds the chlorine after that amount. I learned the hard way, my pool was green no matter how much chlorine a I put. I would love it if you re did this experiment with a glass container instead of a tupper wear that gives out.
then show how if you use the sump pump to drain the water in the gravel, you can empty the pool completely and it would not pop out. :)
Thanks for your comment. When you need to lower your pool water to get of CYA, it is important to only lower it to the point you are able to that is still above ground water level. If you are able to remove and pump away the ground water that is ideal and the safest. If you are only able to lower the pool to half way for example you can do that twice effectively changing 75% of the water. Half and refill...Half and Refill.
i have a calcium issue with my fiberglass pool. I would love to drain it but I'm worried about it popping out. I have a sump pump...but still worried.
Mythbusterrs you are not...so are you trying to claim that fiberglass pools can not pop out of the ground? Do you have the internet? Pictures are everywhere. Its obviously possible since...you know...it happens.
hi you work at yatla dont you
+tyler Scales no, and i don't know what a yatla is. what I do know is that the guys in this video do not know anything about physics, swimming pools or how to conduct a scientific experiment.
In any fiberglass pool there will be blistering to the gel coat, sooner or later. The water will need to be drained to repair. That is the main reason to drain a fiberglass pool. The area that the pool is in will determine the risk, the size, the depth, the duration it will be empty. And yes there is a risk associated with a fiberglass pool.
I believe they pop out here in Canada when the ground water freezes and expands
Happened in Ottawa in the floods a few years ago. It was all over the news.
Never drain a Fiberglass pool? Yeah right, how about when the gelcoat thins and it needs resurfaced? My pool is less than 9 years old, it's white which has now stained and looks like crap. There are thin areas as well...
So funny, just watched a video of a pool popping out of the ground. Not because of material. Just craftsmanship.
The problem is when they get empty without venting the ground through the drain
If it does not pop then it will fall apart in 5 years like the container. These pools should never be sold. I hate telling my customers that I can not fix their pool because this product should not have been sold to them in the first place
I'm sure that you have seen many bad and cheap pools out there. All fiberglass pools are not created the same. Nor are installers. There is a good chance you have not seen a quality fiberglass pool because there are not reasons to have service done. A quality fiberglass pool (like boat) will last for decades and decades.
PLEASE send me one of those mini swimming pool
living in a place with that much water to pop one of these out you dont need a pool.
Where can I get one of these mini demonstrative pools? I am trying to find something like this for an animal habitat that is about 5 feet long and this deep. I appreciate any help !!
I vinyl pool isn't a shell like gunite and fiberglass,it will not float, but ground water will ruin the floor.
There are reasons to drain a fiberglass pool. I am getting a lot of calls to refinish someones fiberglass pool. Now if there is never a reason to drain a fiberglass pool
then how are we to repair the pool. The fiberglass walls have bubbles on the inside walls, and the pool need to be sanded and re finished on the inside. Well here is how to repair the pool, but we have to drain it. So here is what we do. When the pool is drained down 2 feet below the normal tile level. We place a brace against the walls of the shallow end of the pool. If the pool is 16' wide (pretty standard) some are 14' wide. What ever the width a flat board is placed against the wall from top to
where the radius starts to form the the bottom of the pool shell. Then we take a 2'x4" and cut it just enough so it can be wedged against both boards on each side;
These braces are placed every 6' apart.
This brace keeps the walls from caving in and relieves any outside pressure on the pool walls. Now as the pool is drained another 2' down braces are placed where the walls have a lot of space for out side pressure to collapse. This take s little common sense. While draining the pool, we also drain the water from the bottom of the pool by placing a small water whose in the over flow pipe that is at is at the main drain.
When all the braces are in place we take a brace and place it beside the main drain with a back up board underneath the so not to damage the shell and then we
nail it to the cross brace to keep the bottom of the pool from rising up and causing a belly in the shell. When there is about 2' of water in the pool we pull the plug so any water can seep in the drain and come in the pool. This way all the pressure is removed from the pool. Thus the pool is not floating. I have never seen a fiberglass pool float. But I have seen a gunite pool float 3' above the ground. I have seen a fiber glass rip in half after it was installed. I poured the deck around it and the pool and 2 weeks later the new pool ripped apart in the corner. This was a rectangle pool. I have been in the pool business since 1970 and I may have just seen it all.
How do I edit the misspelled words in the blog above
There is no need to drain a fibreglass pool to make small repairs, gelcoat can be applied underwater and will fully cure underwater. The gelcoat will get a milky white surface when cured which can be polished off with a scotchbrite.
For major repairs it is more convenient to drain the pool but not absolutely necessary.
Never back fill with Gravel unless its a very small gravel, because if you use larger gravel, the pressure from the oustside will force the rocks towards the fiberglass and will puncture the shell causing a leak. On the other hand a river sand is used to settle and it packs real fast and easy. And never leaves a chance of puncture holes. Never use just fill dirt eather because it dries and leaves an air pocket between the shell and the fill.

What about draining for winter closures? You need to lower water levels below plumbing.
You don't need to lower the water when you winterize. Another myth that the pool industry hangs onto. A fiberglass pool should be left full at all times. Most manufactures warranties require it.
@@LuxuryPoolsandLiving -40 degrees celcius in winter over here. Plumbing/skimmer would expand and crack immediately. I think you live in southern US??
it all comes down tot he level of the ground water compared to the level of water in the pool. if the ground water is higher than the water in the pool it will push it up. obviously a fiber glass pool will be more susceptible to this compared to concrete. it may as well be a boat filled with water...
Yeah but the earth isnt surrounded with a plastic sterlite tub.
pools need to have cleats and such lips for the dirt to for around to prevent the lift.or sump pump
box on the outside in a gravel bed
The power and lift force generated from buoyancy would blow threw any cleat or as some of the manufactures have named 'rino rods' and different hold down systems with cute names. Buoyancy will lift a concrete pool 4' out of the ground. There is no hold down that will prevent that if a pool is drained.
@@LuxuryPoolsandLiving I guess well agree to disagree.
Dear Lo or should I call you hung? His information is just not complete and he is not providing all the data. I totally agree on your observations about hyrdostatic pressure. This is why sales guys should not do technical briefings :-)
Drainage is the key to a lasting pool build of any kind. My belief it is the number one thing done wrong... that or maybe not teaching customers about water balance.
But it does happen
what about freezing? won't that push up on the pool?
Below grade the temp is much higher than 32 degrees so no it would not freeze
Basic buoyancy, a boat is going to float. You fill a boat with water it's going to sink. He drains that pool with water in the ground it's going to pop out of the hole.
question about gunite pool---is it normal for water to leak into the pool where the pvc pipes stick out? we have had heavy rains and i see water coming in under the pvc pipes on the side of the pool. the gunite was put in 2 weeks ago. my pool builder says its fine....??? i posted a video. you can see the dirt stains under the pvc pipes....thanks for your advice.
If the pipes haven't been epoxied in properly yes
Plaster will seal that.
I understand that concrete and fiberglass pools pop out of the ground, but in most cases, why would there be an equal amount of water be outside
Pools, boats, septic tanks, etc dont float because there is equal water in the vessel than out.... they float because there is MORE water outside than inside... thus buoyancy. Where the ground water comes from and why varies from site to site but having a sump tube or drain to daylight is how you insure that the ground water can be removed and keep the pool safe.
I don’t get it. Your demonstration seems flawed. Maybe I just didn’t understand you properly. In your demonstration, You don’t have significant hydrostatic pressure for the water that’s right outside of the fiberglass. This is because the plastic tote relieves pressure by bowing out. But the earth won’t give so much and therefore you will definitely have a spike in hydrostatic pressure with a little bit of water outside of the fiberglass and no water inside the pool. And yes, it will be like trying to hold a balloon underwater.
in my opinion either would pop out of ground, if the water in ground and pressure are right. I suppose my meaning if pool is located near a hill after a rain in gets drained to remove mud and debris that is mostly when it happens. IMO.
:20 they can't take you to one, they can't show you one - nuff said
If ghis was sized up to scale i doubt thar much rain would fall and if it did it would be disbursed
Gravel bed and concrete collar will cover that
Totally drain the pool dude that is the whole point!!!!
That's why they are installed with "GRAVEL" around them, not mud!
Such a poor test. These pools pop out like corks. Even concrete.
When you winterize the pool you only take out as much water as necessary below the Jets! Plus the pool is being serviced you never drain your pool.
If you happen to have to replace your liner which is usually every 10 to 15 years. That depends on how well you keep up on your chemicals! Anyways replacing the liner only takes three hours. Give or take! This guy is just worried because his pool sales were down because he knows their shit. I will videotape an update on the next house that I go to that has a fiberglass pool with all types of problems. Always stick with vinyl! Concrete at worst never use fiberglass
That made no sense.
Lots of this happens in Florida because of their water content in the grounds. If in California 90 percent you are ok
This is not accurate why would they put it in a plastic tray not install it in the ground where it goes than seal off with some cement?
The point is that water AROUND an object (vessel) with water also IN that object does not create buoyancy and float. Water around an object with not water in that object, buoyancy is created and the pool can lift. Thus - DONT DRAIN a pool without professional help. They will not just 'POP' out of the ground on their own for no reason.
If the stone is a messier material than in real life, then the recreation is pointless.
A real one has a concrete collar
Just trust me, im a professional (says the used car salesman 😂😂😂🎉🎉🎉)
Richard has no clue of what he is talking about.
It the owner who drains the pool to clean it out.
This is misleading information
So I take it you sell fiberglass pools? You never drained the water out of the pool. Do that and make a video! If you drain that pool all the way it will float instantly this is a joke and so is the demonstation of nothing.
Why would you build a pool in a pool.
When sand gets wet it turns to liquid.
It does. It is also what pushes on the walls - Hydrostatic pressure
You say you never have to drain a fiberglass pool, correct? What about New Jersey in January? When that freezing water turns to ice, something has to give, your liner!!
I seen ice crack car engine block. This is when your pool can pop out of the ground, when you have to drain it, to prevent cracking. Insurance companies require special coverage for fiberglass pools, because of the popping out of the ground problem. Your video is so lame, Take all the water out of the pool, then add the ground water!!!!!
Richard- You NEVER drain a pool. Period. As for 'Freezing' you must have never mad ice with an ice cube tray. Ice will expand up.
PS- if there is water around the pool AND water IN the pool....NOTHING HAPPENS.
thanks,
Luxury Pools and Living Ohio i have a fiberglass pool 5900 gallons and i have a calcium issue. i cannot get rid of it. my installer said the only way is wet sand paper. I have triedchemicals to no avail. please advise. walls are white floor is getting white and pool is blue. im sick.
I've had a fiberglass pool for 25 years now... no popping out of the ground... that said. We were told to NEVER drain the pool completely, sooo, we never have! At my pools age it has faded though and I'd love to be able to re-color the surface.....
Audio too bad
It's not gonna pop out when it's full of water,its if you drain it that's the problem.
THis os so unscientific. The level of the water in the "pool" is higher than the water in the tupperware could ever be (it would flow out). Therefore it will never "pop up". Drain some water out of the "pool' and itwill pop up for sure.
Exactly the point Kevin- If there is water in the pool- it will not just pop out of the ground. Unlike a liner walking a fiberglass pool is stable at even equal water levels.
Cheers!
Great video...very informative regarding pools. Always nice to see what everyone is talking about.
This is false and the reason why I say it is because I’ve had first hand experience with it . Installed a pool was full and backfilled with gravel just as the illustration and the pool rose six inches at the shallow end . So therefore this is fake news not to scale. I’ve known other installers to have same issue. Must keep pump in well point till deck is poured.
Jason- Thanks for your comment. The point here is that if there is water in the pool and that water matches the water around the pool the pool will not float. Not enough boyancy is created to lift it. You can demonstrate the same thing in your kitchen sink. Place a casserole bowl in the sink. Fill it. Fill the sink to the same level. It will not float.

See the you tube LINK inthe description above.
Friend.....Get educated. ANY ANY ANY pool will lift or pop when empty with ground water. Physics 101
Lol. I understand the point of the video but "you never have to drain a fiberglass pool"??!! How do you repaint it/refinish it when the gelcoat/paint/coating wears down to the fiberglass?!!
"Fiberglass pools don't just pop out of the ground" ... Here's one for you:
hi nice comment
Please what do you mean? Do they or don’t they? I am in between buying Fiberglass or Kayak and I know nothing....please I need a lot of help....🙏🏻 need to make a decision now. Thanks so much!
It makes sense, I see it happening if you build your pool on the Louisiana Swampland..Pure Sales Pitch Quackery.
Let's try increasing the size of that plastic container that the scale model fiber glass pool sits in and expand it to about 5 to ten times the area of the pool (this would be more accurate to an actual in ground pool). Then completely fill the container (until the water level in it surrounding the model fiber glass pool matches the top rim of the model fiber glass pool) with water and then drain the water from the model fiber glass pool. While draining the water from the fiber glass pool you will undoubtedly notice the model fiber glass pool begin to lift. This will occur because the water in the model fiber glass pool as it is displaced will no longer be equal to the surrounding water area of the plastic container to which it is contained in. Your video demonstration does not account for complete water displacement from the model fiber glass pool and inaccurately depicts equal water area ratio between the model fiber glass pool and the surrounding water within the plastic container to which the model fiber glass pool resides in. This whole video is a misrepresentation and misrepresents the scenerio you are describing in your video.
Expand it 5-10 times the area of the pool? Where on earth did you ever see an installer dig that much to put a FG pool in? My pool was dug out no more than 2-3 ft around the side walls of the pool. From a scale standpoint, this video depicts almost exactly what my experience was based on my builders install.
Wow very scientific simulation. 🤣
137/137 thumbs up/down
I have the swing vote
Any pool can pop out of the ground due to hydrostatic pressure. I grew up in a neighborhood in which every house had a pool and I cleaned them, done research, seen different methods etc. a hydrostatic relief valve and groundwater pump near the pool to remove groundwater when draining is normal. Very important: replace the relief valve regularly to keep it functional. Always get a second opinion and do your own research and come to your own conclusion because it's you who can be stuck with a pool popped out of the ground.

BS!
Thanks for the comment Joe......So you saying water around a vessel with air inside will cause buoyancy? Nice! I would tend to agree with that observations. Like a boat!......LOL...The real question is WHY do you need to drain a fiberglass pool? to change the liner.....Nooooo...To resurface it or paint it?....NOooooo. I give up. WHY would you need to drain a fiberglass pool?
well how do you repair all those blisters and fix where the gelcoat has worn away on my 34 year old pool? i live in florida and if you dig more than 6 feet you will hit water where i live. i also dont see anywhere where there is a pressure relief pipe. anyone that can help please let me know thanks
Here is a Viking pool we TRIED to pop and could not. search 'Viking pool removal' by Leisure pools Ohio
He's a salesman. Fibreglass pools do need draining from time to time. Gelcoat degrades over time and is not maintenance free.
If a quality fiberglass pool is cared for it will not need drained completely. If the need does arise its not that big of deal IF YOU have a sump tube / well point installed.
ruclips.net/video/r980exBfzb0/видео.html
I cannot agree with so many of his assertions, In order for the pool to pop out, it most likely due to water UNDER the pool v. the weight of the water IN the pool. I live in FL and the water table is high, and any type of pool is prone to poppling out if it is left empty or low on water for any amount of time, and heavy rains will further raise the water table under the pool and will "float" the pool out of the ground. I have Pebbletec surface on my 30 year old pool and with proper chemistry maintenance the water never needs a complete change. Always choose Pebbletec for your inground pool surface
It work in California...Move to California.....
Freezing does not have anymore effect on a fiberglass pool than ice does on an ice cube tray....See Fiberglass Pools Freezes in Winter - What happens when your pool freezes?
Lol 😂 didn’t work
