I've owned an in-ground vinyl pool for many years. I have used several pool companies over the years. Each pool person I have talked to recommends draining no more than half the water at any time. This is something that is typically done for the winterization process. It was explained to me that the weight and pressure of the water in the pool provides structural integrity, preventing any chance of the walls collapsing.

On the other hand, there are times when you need to completely drain a pool because the water just has too many dissolved solids in it after years of chemicals, or sometimes, a pernicious algae condition can only be solved by draining the pool, scrubbing it down, and refilling with fresh water.

If you need to drain a pool completely and refill it, the whole process should be completed as quickly as possible. I don't think, given all the variables, how specific I can be, but personally, I wouldn't want to see my pool without water for longer than 24 hours.

New HeadlineOnce filled and used, you do not want to drain an in ground vinyl lined pool. I made this mistake once and recently saw my neighbor make the same mistake on a two year old liner. Over time the liner seems to become less pliable and when the pool is drained the liner contracts. When you refill the pool the liner does not expand to the previous shape and often rips. This is an expensive error.

Why does a pool liner get wrinkles after excessive rain?

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.

Why does an inground pool have wrinkles on the bottom and sides?

Hydrostatic pressure or poor water chemistry. If the watertable is high the liner will float and when the water recedes will create a suction and pinch the liner. If your alkalinity and stabilizer levels are low the sanitizer will not have any molecules to attach to so it goes after the vinyl. The pulls the plastizer out the vinyl and causes it to prematurely fade and wrinkle.

Do inground vinyl liners frequently float?

The liner should not float at all. The pressure or weight of the water is what holds it down. There has to be either a leak where water is getting under or behind it or maybe ground water is forcing it up. This is sometimesa problem in the southern states where the water table is closer to the ground surface.

Can an inground pool be saved when the vinyl liner was removed and there is a groundwater in the deepest point in the pool?

yes it can be saved. You will have to put points in the ground and rent a diaphragm pump or buy one and dewater the pool. Most instances the diaphragm pump has to run while the liner is being put in because if you turn it off and you have a high water table in ur area, any water it sucked out of ur pool will begin to fill up again.

Is it safer to Drain an inground pool for winter?

Never drain an inground pool, ever. The pressure from the gound water will either pop it out of the ground (with gunite or fiberglass), or cause the liner to pull off the walls and floors and float (vinyl). You need to make sure the ground water is pumped down before taking water out of the pool. Even if you did empty the pool down already and it "seems" okay, by the time all the snow melts in the spring, and the ground water rises, you could be royally screwed.

To cut down on heating costs will an inground vinyl liner pool with a dark-colored vinyl liner be noticeably warmer than one with a light-colored liner?

A darker color will absorb and retain some of this heat/light, most will be absorbed or reflected by the water. Solar heating panels that circulate the water through the panels then back to the pool or alternatively a solar cover will do much more to heat the pool water.

You can probably find the plumbing to step down to the right size but the pool pump will have more water flow then a garden hose can safely handle. Your going to ruin either the pump or yourself.
