If you have water behind your vinyl in ground pool liner, you should first lower the water in the pool to normal levels if it is over-filled. Make sure that the vacuum pipe is clear, unclog it if it is not. Once it is unblocked let the water from behind the liner flow out.
You don't! Water must be emptied, liner reset in place and pool refilled
Probably ground water or condensation. The liner cannot leak unless it has hole in it.
Try using very hot water to heat the liner..
I HAVE THIS PROBLEM. THE POOL PRO I SPOKE TO SAID IT IS A PROBLEM AND IT NEEDS TO BE REMOVED. A GARDEN HOSE ATTACHED TO A PUMP BEHIND THE LINER IN A CORNER SHOULD DO IT ACCORDING TO HIM. IF IT IS A PERSISTENT PROBLEM YOU NEED TO DO IT WEEKLY. Had a vinyl liner pool 21 yrs and always have water behind liner after a major rain or water the flowers too long. We installed a PVC pipe in the corner with a cap on the end with pencil size holes drilled in the cap.Then cut a hole in the steel wall and under the walk way around the pool and attached a water hose to the end coming out with a water hose and use a utility pump to pump the water from behind the liner to a drain pipe running in a ditch away from the pool. It's a pain..but the water weight in the pool is not surpose to allow the water behind the liner to rise, but guess what?... is does. Only thing we can come up with is we have clay all the way down and have sometype of pooling to the hole. We are installing French ddrains around the pools sides this summer.Good luck with your problem with water behind the liner!
By the liner bulging, I assume you are refering to water behind the liner due to excessive hydrostatic pressure. To correct, you need to remove the excess water. You need a pump and a length of smooth flexible hose, spa flex is best. 1. Unhook the liner from the bead receptor in shallow end of pool 2. Place hose into the water behind the liner (towards the bottom of the pool wall) 3. attach hose to front of the pump 4. Attach another hose to the discharge side of the pump 5. start pump and send discharged water back into the pool. 6.use a pool brush to carefully smooth the liner back into place. 7. When water recedes slowly pull suction hose from behind the liner. Note:You do not want to remove all the water just the majority of it. Otherwise it will be difficult to remove the hose. The remainder of the water behind the liner will disipate as the ground dries and the liner watyer pressure pushes it out..
1. determine where your pool is leaking (liner or plumbing) and repair.
sounds like there is ground water getting in there somehow
it is the water ouzel
Either your liner is floating because of water is behind it, which will evaporate away as long as it is a minimal amount. If you do not have liner lock in the coping it will pull out from the wall by breaking the seal. Pull the liner back to the coping insertion to lock it back into the coping and install the liner lock ( T-shaped poly bead that slips into coping beadlock) Cheap Cure!! Or, unfortunatly, your liner is giving way and it is taking on water.
so that they can push the water behind them and move
One cause is a leak.. A small hole/tear in the liner allows water to get behind/under the liner. Now, without the water pressure pressing against it (or, with equal pressure above and below), the liner 'floats' away from the ground/wall. If you see an increase in the number or severity of the wrinkles, you likely have a small hole somewhere...
If water is getting behind the liner, sorry to say you have a leak. This will also cause wrinkles. Check around main drain if you have one.
How are you planning on making the pool water tight? If you want to use a Vinyl Liner, you should consult the dealer you are planning on ordering the liner from. A lot of Vinyl Liner manufactures will not make a liner for that pool.
Fiberglass pools are less susceptible to having problems with the finish if your water chemistry is off. They do tend to have some problems with warping that you won't have with a cement pool. The fiberglass liner is usually cheaper also.
In the water, see it swimming. Animals were hiding behind the rocks Ya
He is kind of swimming in the water behind the waterfall Shock him Magikarp comes out of water. This place is also in a shady area.
I've heard that the liner needs the water to prevent it from drying out. Also keeps the pool upright with the water weight. Wind can't blow walls down when filled.
They have really powerful muscles in the hind legs, helping them to push through the water. They have webbed feet to help in pushing the water behind.
Some types of bacteria and fungus found in the soil can actually penetrate through a vinyl liner and cause stains to appear on the liner. Usually they will start off as spotted or cloud-like formations on the liner. Algaecides used in the pool water have little if any effect on the stains caused from bacteria, since it doesn't get to the source of the bacteria in the soil. If a pool is known to have a problem with bacteria staining the liner, the ground underneath the liner may be treated with a solution of one half household chlorine bleach and one half water. Mix the bleach in the water and mist the floor of the pool with a small garden sprayer three or four times prior to dropping the new liner in the pool. After the last application of bleach solution, wait several hours before dropping the liner; making sure the solution has been absorbed into the ground.
Rain. It's normally just ground water that takes a while to drain away. You may also have a hole you haven't detected. It happened to me. I will agree to the leak answer but not the rain. There are a few scenario's to think about. If you have an inground pool and your pulling the liner out of the track and you see water actually behind the liner, and im not talking just because the wall is wet, im saying if there is actually standing water behind the liner, you have a leak, and most likely its a hole or holes in your liner. Now if you feel water under the liner on the floor, which should only be in the deep end, then you could either have a hole or holes in the liner, and the water hasn't soaked into the ground which if you have a concrete bottom then most likely its not gonna soak up anywhere unless it makes its way torwards the pool walls. And besides if you have an inground that is FULL of water, its impossible for any ground water or water from leaks to stand behind your liner. There is more pressure from a full pool of water then what is being pushed up from ground water, therefore your pool water will push all that water in the ground and you wont feel a thing. The ONLY way your gonna know if you have high water is either A: you know for a fact that you do or B: you start to drain your water out of the pool and you see the liner starting to float on the deep end floor. But you shouldn't be draining your pool completely out if you have liner anyways. The water is whats holding that liner in place and if you drain it out, your risking that it moves, and you cant get it back into place and you end up with wrinkles everywhere or worst case it rips by chance. Any company that installs liners uses special vacs to hold liners in place while its filling and stretching to the shape of the pool. Now your WORST nightmare of draining your pool out is if you do have high water and you drain it out, your risking the high water breaking the bottom of your pool floor and even the slopes ultimately leading to your pool quite possibly caving in. I've worked on pools and installed pools for 10 years and trust me I've seen it happen. But the best answer to your question would most likely be you have a hole or holes that is causing it. Simple way to find out but is time consuming is get some colored die, doesnt matter which, and dive around the area where you know you see the water behind the liner and die test the liner and see if any of the die goes through any holes. You found the problem then. There are pipes running next to the pool. Some of which pull the water to the pump for filtration or vacuuming . Others bring the water back to the pool through the jets. There could be cracks in the pipes causing the problem. Around my pool there were two pipes that were cracked and the water made its way behind the line. It was obvious that the pipes were broken for a long time because the water had created a underground cavity right next to the pool. So that is something else you can look into.
The size of the hole will be the determining factor but a small hole or cut can be patched with a vinyl repair kit which will work under water.
The water table in you area has risen above the normal level and ground water made the liner float, when the water table went back down your liner did not go back the same as it was
You could try spraying straight bleach from a spray bottle, and then rinse with either reverse-osmosis or distilled water.
The symbol for a swimming area (on Google Earth or likewise) is a human figure, torso up, arm up as if breathing in freestyle, behind a wavy line that signifies water.
