Let a pool pro. do it for you. Or you will be paying for a new pool.Never empty a pool unless you have some type of well point system, de-watering system around you're in ground pool. If You're pool installer encountered water,clay,any kind of surface water, they had to put a de-watering system to install you're pool.A Good pool co. will leave the system in when they are finished. But, do not drain until you call the installer.

You can but be careful that there is not a great deal of ground water around the outside of the pool if you have one make sure the hydrostatic valve at the bottom of the pool will allow water from below the pool to enter the pool as it is supposed too. if there is a great deal of ground water the danger is that your pool will float out of the ground.

Should the hydrostatic valve be left open when it is raining?

A "relief valve" can only be accessed when the pool is empty, and no swimming pool should ever be left empty. The only exception is when absolutely necessary due to repair or resurfacing, and that should be completed within the shortest possible time. Any pool that is empty, and that has a relief valve, should have the valve removed for the entire time, regardless of the weather forecast. A "hydrostatic" relief valve opens and closes when needed as it attempts to equalize the pool water pressure with the ground water pressure. Human intervention is not involved because the pool is still filled. Hydrostatic valves are great in theory, but seldom work after a few years.

How does a hydrostatic valve work?

A Hydrostatic valve is basically a plug that stop water coming down out of the pool, but when the water pressure under the pool gets higher then the pressure in the pool it will let water into the pool from underneath in order to stop the pool from floating in ground water.

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.

What would cause a lump at the bottom of a fiberglass pool?

The most likely cause is hydrostatic pressure from underground water. This can be a very dangerous problem for the pool and I would contact the installer immediately for an onsite consultation. If it is hydrostatic pressure and is not relieved, the pool can be permanently damaged.

When is it safe to drain an inground pool?

When draining an in ground pool you must always be sure that groundwater surrounding the pool is not high enough to cause the pool to start to float. Even a concrete pool Will float if the groundwater under it is too high. Many pools are fitted with a hydrostatic valve in the deepest part of the pool to allow ground water into the pool if the water pressure on the outside of the pool gets too high.

I want to repaint my 12ft inground pool. Can i empty it without any problems?

make sure u remove the plug in the drain at the bottom of the pool,this allows any water that may have accumulated under the pool from seepage to evaporate and equalizes the pressure that may be created by emptying ur pool. You will need to go to Lowe's or Home Depot and buy a high power pump to empty the pool. Also you will need an unclogged drain near the pool for all the water to empty into.

I think it is not advisable to leave the swimming pool empty during winter times. Snows and falling branches of trees and leaves can harm your swimming pool. There are some pool covers that you can use and designed for winters like Pool Leaf Covers and Winter Covers.

Can you empty an in-ground pool when closing for winter?

Probably not a good idea. an empty pool is always in danger of floating if ground water gets under it. If you do keep it while it is empty make sure the hydrostatic valve works and that no water is able to build up under any part of the pool.

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.
