I would definitely leave the water in the pool in order to avoid the actual pool shell from popping out of the ground due to lack of water pressure. The water in the pool acts as a downward force...you don't want your pool shell to pop out of the ground under any circumstances...and any pool going through a foreclosure is going to need a professional cleaning anyway, so leaving in the water is not a problem at all.

What is the best way to clean a algae laden green pool resulting from a house foreclosure and sitting empty for months on end?
Drain the pool, acid wash it, refill, apply proper chemical levels, easy as that!
Can you just drain your pool and start fresh in the spring?
You can. but you should not leave an in ground pool empty for any period of time. Ground water building up around it is capable of even lifting an empty concrete pool out of the ground.
How do you locate the leak on an easy set swimming pool when empty?
If the ground on the outside of the pool is is reasonably wet you may find that water will seep into the pool where it leaks. Be careful with an empty pool ground water can make them float up and out of position if you do not have a hydrostatic valve in the bottom.
How long can an in-ground pool remain completely drained?
The pool should stay empty for as short a time as possible. When the pool is empty the walls are subject to relativley extreme changes in temperature, compared with the stable temperatures of water. Shrinking and expanding (with temperature changes) of the pool wall surface will result in cracking. You then face the joys and expense of repairing the cracks. The bottom line is: Empty the pool only when you need to, do whatever you intended to do while the pool is empty - and start refilling it immediately. Just wanted to add that a pool left empty can "float"..that is to say it pops out of the ground, rising above ground level several inches or more. The ground surrounding the pool, especially if it is wet, is heavier than the pool surface, and puts pressure on the pool walls, which could cause tehm to crack, or "float" the pool. Having said that, I had my pool empty for a long time before I had it re-plastered and nothing happened to it. :)
If a gunite pool is empty for extended period of time what damage if any will there be to the plaster etc?
If a pool is left empty, it will lift partially out of the ground due to moisture under the pool after a heavy rain.
Why did your fiberglass pool pop out of the ground?
The pool has popped out of the ground because it was was forced up by ground water. If a pool is left empty ground water can build up underneath it causing the pool to start to float, Whenever a pool is drained a way of getting rid of ground water has to be set up otherwise there is the risk of this happening.
Can a concrete pool pop?
If you mean can a concrete pool pop up out of the ground then the answer is Yes it can. All you need is an empty or partially empty concrete pool and a lot of ground water around it once the ground water around the outside of the pool builds up enough the pool will start to float. I have seen it happen several times over the years. To avoid this happening most pools have a hydrostatic valve fitted in the bottom of the pool to allow ground water into the pool when there is a build up of water pressure outside the pool it flows into the pool to stop it from floating.
If an in-ground plaster pool is left empty for years can there be damage to the deck or pool?
Yes. Suggest you inspect pool and drain closely for cracks or other damage.
Drain very bottom of pool no working why?
Perhaps it is not a drain but a hydrostatic valve. These are fitted at the bottoms of pools to let ground water that has built up under an empty pool into the pool in order to stop it from floating out of the ground.
Where is the hydrostatic drain valve?
The Hydrostatic valve is usually on the lowest part of the pools floor. The hydrostatic valve is there to protect the pool from being lifted by ground water in the event that it is empty. it allows the ground water under the pool to get into the pool thereby stopping it from floating out of the ground on top of the ground water.
Can you empty and then refill your dirty gunite pool?
* Yes, you can drain it. DO NOT leave it empty, however, but refill promptly. If the pool is empty and there is a lot of water in the ground soil, it could cause the pool to float and crack. == == * I have had this house for 4 years and have drained my gunite pool every spring, acid-washed it and refilled it. So far no problems. It does need resurfacing, but not because of what we did. It needed that when we bought the house. I understand that the cost of that is about $10,000. Which means... it might rather be a pond, or a cemented area with an above-ground pool. * Pools should not be drained completely unless the water table is low. Otherwise water table pressure can damage an empty pool. I never drain my in-ground pool more than 18" below the deck, and keep chlorine tablets in floaters in the pool all winter, which cuts down on brackishness. Removing cover & cleaning in spring just means brushing & vacuuming everything to the filter, then backwash. Sparkling water in one or two days. * When I lived in Texas, people with this problem installed plastic liners. Some of the ones I saw looked like a tiled pool.
Is it true that an inground pool may 'pop up' out of the ground when drained?
Yes it is true. if you empty a pool and the ground-water level is high enough, the pool turns from being a 'pool', to being a 'boat'. I have personally witnessed the event. A 45ft concrete (gunite) pool while being emptied, with the discharge water being pumped out close to the pool - and whammo!!. It was like the second coming of Christ!. A huge noise, and the pool reared itself out of the ground. We were inside the house and heard the noise and only knew what happened when we looked outside and saw the pool angled out of the ground, 4 ft higher at one end than it started out at.
