Wait for the right time to empty your shell pool

Emptying your entire pool is not a trivial act for the structure of your pool . Done in the wrong season, the latter can come out of its foundation, under the pressure of waterlogged ground. This is the reason why it is better to avoid autumn and winter and wait patiently for the good weather to undertake the emptying of your shell pool .

However, be sure to check the weather forecast beforehand so as not to choose days that are too sunny. Indeed, the sun can quickly irreversibly damage the coating of your shell pool.

Once emptied, do not wait more than 24 hours to refill your pool; this could cause damage to the structure of your pool.

Warn your neighbors a few days before emptying your shell pool

This may seem obvious, but emptying thousands of m3 of water is not without consequences for your soil and that of your neighbors (risk of flooding, infiltration through the ground). For this reason, it is imperative, as a first step, that you notify your municipality : the latter will give you the arrangements to take to evacuate the water without risk. Secondly, notify your neighbors of the date of your emptying so that they can check that no infiltration through the ground occurs at their home.

Once your municipality and the neighborhood have been notified, remember to stop all treatment of your pool water at least 10 days before emptying to avoid soil pollution .

Some steps to follow on the day of the oil change

Are your floors dry? Are your neighbors and your municipality notified of your emptying?

Great! You can now start emptying your pool in several batches. This way, you will give your ground time to absorb the water and drain it away. This will avoid any risk of flooding and infiltration through the ground.

 Once your pool is emptied, you must absolutely prevent the structure from coming off its base, at the risk of it cracking or breaking. To do this, remember to leave at least 20 centimetres of water inside your shell pool. Use beams – installed widthwise – to support the shell of your pool for the entire duration of the emptying. In order to protect the coating at the contact points, place cardboard sheets or any other smooth surface between it and the beam.

Finally, don't delay in refilling your pool; the less time it spends without water, the better it will be!
