The answer is always NO. Above ground pools need the weight of the water in them to provide an optimal level of stability. Without water supporting the wall you run the risk of the pool wall coming out of the track. Also without water in the pool the liner can shrink and no longer fit your pool.
Once water is removed (and subsequently, the interior hydrostatic pressure), if there's an influx of groundwater, it will push the pool up and out of place. As a general rule, you shouldn't keep any pool empty for longer than it needs to be. Get the work done that you needed to do and refill it as soon as possible.
An empty pool (or as little as 1/4 filled) and an exposed liner on a hot day can cause the liner to shrink from the heat and deem the liner useless. An empty pool is also susceptible to collapse. Especially, in high winds and/or bad weather.
Why shouldn't you drain a pool? Swimming pools are designed to be filled with water. They get used to the heavy weight and pressure of the water over time, so if that's taken away, even for a short time, it can cause serious damage to pool walls, floors and liners.
You'll need to keep draining water off the cover with a pump or siphon to protect it from damage. Important: Never drain an above ground pool completely when winterizing. Your vinyl liner can dry out, shortening its life considerably.
If the pool ever needs to be drained to replace the water or to maintain the plaster, it should never be left empty for more than eight to ten days at the most. More than this may cause the plaster to dry out and crack. Keep your pool full for best results.
Whether you drained yours partially or completely, the rules for refilling an above-ground pool are the same. At the end of the day, a pool is designed to be full of water.
Much of this rain water penetrates into the ground, raising the inground water table, which creates a lot of hydrostatic pressure pushing up on the pool. After the water table raises enough, the pool may float or pop up out of the ground.
Filling your pool with dirt is the fastest and most affordable way to get rid of a pool because there's no need to remove your concrete or metal shell. This saves on both labor and hauling costs. However, filling a pool with dirt is still a delicate process that requires careful preparation, drainage, and demolition.
While there are many myths about fiberglass pools, the one thing you should NEVER EVER do is DRAIN your fiberglass pool without professional help. Let me say that again, NEVER drain your fiberglass pool for any reason. In fact, we recommend NEVER letting the water level drop more than 2-3 inches below the skimmer!
Above-Ground Pools
If you have an above-ground pool with a vinyl pool liner, drain the pool to about 1 inch below the bottom of the skimmer mouth. It's acceptable to drain the pool a few more inches below that if you live in an area that gets heavy precipitation during the winter months.
While you may think the best thing to do to prepare for winter is to drain the pool, a vinyl-lined pool should not be drained under regular circumstances. Since the water secures it to the pool, draining it can cause the liner to lose elasticity. The liner can shrink causing tears and rips upon refilling.
Shock and Chlorinate Your Pool
Shocking kills any bacteria that might linger in your pool during the winter. We recommend shocking a few days before you close the pool. If that is not possible, make sure to shock the pool the night before you close it for winter.
It is best to close your pool when the temperature of the water is consistently below 60 degrees. Once the water temperature drops below 60 degrees, microorganisms and algae cannot grow and become dormant for the winter season.
Close the pool for winter – but don't drain it.
In winter, the water in your pool is still your friend. Especially when properly winterized, it helps to protect the pool liner, keep it clean and prevent unnecessary damage from debris, harsh weather and other factors.
White vinegar can be used as an alternative to other chemicals when cleaning your above ground pool liner. Since it is a mild acid, it will help to remove stains and debris from the liner. Like you would with bleach, apply the vinegar with a sponge, put it all over the liner, and then scrub it with a brush.
At an average of $0.004 per gallon, city water is the most inexpensive and most popular option. For 15,000 to 30,000 gallons, you'll pay between $60 and $120.
Pools Waste Water
A well-maintained swimming pool that does not have any leaks should not have to be drained or refilled every year—even every two or three years.
