I'm assuming that you have an inground vinyl lined pool. This is a chronic problem with inground vinyl lined pools, and is due to ground water being higher than the level of the water in your pool. The pressure of the ground water is greater than the pressure exerted by your pool water, and the liner floats. A half baked solution, is to wait until the ground is no longer saturated before removing water. The real solution is to provide a way for the ground water underneath your liner to be removed. This can be a passive system with a small pipe going under your liner and allowing the ground water to drain off (but this only works if you can keep all parts of that pipe below the level of the water in the pool-which depends completely on the pitch of the ground in your yard), or an active pumping system which pumps the ground water out to a drain.

What causes a pool liner to float?

A vinyl liner floats because of excessive ground water. This usually happens because of extreme weather conditions such as rain or snow. A broken pipe, proximity to bodies of water i.e. creeks, ponds, and lakes are also causes of floating liners.Also if the pH value of the pool is to low (to acidic) because the acidic water will eat away the stuff in between the tiles of the pool.

How do you get wrinkles out of a pool liner?

Wrinkles in Swimming Pool LinersHere is advice: I ended up with a few large wrinkles in our new IG pool. We had a bad winter and a wet spring. The water table rose and left wrinkles. I waited for a good rain to bring the water table up a bit. I then gently used a wooden handled red rubber toilet plunger. I plunged right next to a wrinkle and gently pulled up and away. Took some time but a lot less then a liner reset from the pool place by me ($525). Worked like a charm.What I did is to heat the pool to about 92 degrees or higher to make the liner softer. Then, I used my rubber "broom" on the squeegee side and started smoothing from the center toward the edge. Note: my wrinkles were not tightly pinched together so I had some movement still possible. I got the rubber "broom" from one of those home shows where they demo it as a better broom for carpets and floors. Mine has a straight edge opposite the bristles that acts as a squeegee. The whole edges are a soft rubber that won't scratch the liner, and I used care in the operation to make sure nothing got ripped.You can try to remove them with a broom, squegee, or your foot. The only way to do it right is drain the pool,use a big vacuum cleaner between the liner and the pool frame and let the vacuum do it's work. Then make sure that ground water doens't get between the liner and the base during the winter. I had to construct a french drain all the way around the pool and pump ground water all winter to keep this from happening. (Built pool on under ground spring, I think).You can actually pull the vinyl liner away from the coping and use a vacuum smoothing out the wrinkle - this is the way that pool are initially installed - not a big problem - don't worry.You might try using a regular bathroom type plunger. We recently had a new liner placed in our pool and the guys who installed it told us that we could do that if we ever got a wrinkle.AnswerIf it is fairly new liner empty the pool put a blower between the liner and outer area to lift the liner, Then reverse the process. While deflating in your stocking feet push pull and tug gently to get the wrinkles out. Kinda like making a big bed.

Is there an automatic pump ssytem to drain a pool with a liner if it fills too much?

Use your winter pool cover pump and mount it to the top step. I only use this when I am leaving town and expecting rain.

When having a vinyl liner replaced are a few small folds and wrinkles in a corner acceptable?

This is more of a judgment call then a question. If you feel that the contractor didn't do a good job have them come back and correct the wrinkles, but small folds and wrinkles can easily be worked out if you spend a few minutes playing with them. We didn't have folds at first but after the first heavy rain we had some water under the liner in the shallow end and after the water subsided we were left with pretty hefty folds. These folds collect any and all bits of "dust" and small bugs or whatever else lands in it. It doesn't "hurt" to have the folds there but it is unsightly and isn't great to have to walk on it when swimming. Would you except folds in carpet after a new carpet was installed?? The installer or builder should remove or replace at his cost.. If the liner had no wrinkles at install then it was a good install. The installer should have a good idea of soil content or drainage in the yard. The wrinkles were not due to bad install. They were due to the water weight in the soil out weighing the water in the pool. Either the pool was not completely full or the yard has a serious drain issue. Either way the wrinkles will continue to come back after a heavy rain storm if the drainage issue is not addressed. The first time is FREE. The second time is a nice gesture. The third time and any time after that is on the homeowners expense.

What does rain do to the pH of a pool?

Rain if it is acidic can lower the pH of a swimming pool.

Can you swim at swimming pool after rain?

Yes, not a big issue in this. You can swim in swimming pool even after rain but it is good to avoid swimming in pool during rain and thunderstorm because of lightning.

What would cause water to keep getting behind an inground pool liner?

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.

Can you empty and then refill your dirty vinyl pool?

YES, PUMP IT OUT AND THEN USE A SHOP VAC OR A SUMP PUMP TO DRAIN THE NASTY STUFF ON THE BOTTOM. WE DID NOT OPEN OUR POOL FOR A SEASON AND DID NOT COVER IT FOR THE FIRST WINTER, BUT WE COVERED IT THIS WINTER. WE JUST OPENED IT UP AND USED THE ABOVE TECHNIQUE AND WE ARE UP AND RUNNING NOW. WE HAD TO USE A PRESSURE WASHER TO CLEAN SOME SPOTS BUT WITH ALOT OF HARD WORD AND IT IS OPENED.WE HAVE SOME STAINS BUT WE ARE HOPING THEY WILL LIGHTEN WITH THE SUN AND CHEMICALS OVER THE SUMMER. Was told not to but we were at wits end, this past winter the pool didnt get covered and the pool was real nasty we tried expensive chemicals just a waste of money, today we drained the pool and then diluted Clorox bleach in a bucket cleaned the vinyl liner (looks like new)and now the pool is getting refilled as long as you have time and patience a shop vac and a sump pump you can do it..... good luck & happy swimming It is not advised to drain your vinyl liner pool, or allow it to leak out below the level of the walls. The water in the pool holds the liner tightly against the walls and floor. If the water is removed, the liner must be reset with a vacuum to suck the liner into place while filling. Otherwise, large wrinkles may appear when filling a loose fitting liner. In addition, an empty liner pool may allow rain water to seep in under the walls, washing away and destroying the specifically contoured shape of the floor. There also exists the risk of a wall collapsing or caving in. If you decide to temp fate, you still may want to consult a local professional for assistance or advice.

Is it problematic to have water get behind 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!

What are unique characteristics of the forest?

excessive rain, a thick canopy.

Where do wildcats get there water from?

Rain, pool, beach

What should you do to your pool after it rains?

Nothing in particular. The chlorine in the pool should take care of the rainwater in the pool. But, rain or no rain, be sure to keep checking your pool water for chlorine, acidity, alkalinity, etc.... in order to maintain safe and clean water. The sun does as much damage to pool water as rain. You MUST be didligent in checking the chemistry of your pool. Good luck!
