How to protect the pool in winter

Swimming pool, it’s time to close

With the end of the summer we have to deal with one of the most hateful tasks: close the pool for the winter. A sad moment, because it marks the end of the summer, of afternoons in the sun, carefree baths, happy days spent soaking with friends.

However, it is an operation that must be done well, in order to preserve the pool at its best during the cold season, so that it is perfect when it is time to reopen it. In short, hard work, but someone will have to do it!

So how do you proceed? First, before analyzing how to close the pool it is good to understand why it is important that this operation is done in a workmanlike manner and above all how to intervene in the best way for the pool cover.

Why prepare the pool for winter

First of all, we must start from a premise: the cold season causes several danni to the tank if it is not protected in the best way.

The main risks are obviously related to bad weather: the possible frost that characterizes many areas of Italy, as well as the rpond of water in fact, in the pipes they can cause considerable damage to the structure.

For those who live near the sea, there are also the damage caused by the saltiness.

Pool to clean
One of the main questions to answer is: the should the pool be emptied in winter?

According to experts, it is never convenient to empty the tub during the winter, or at least not entirely. The advice is therefore to always leave at least half the pool full.

This is because the cold and the sun can cause considerable damage to the coating if it is not protected from water. Another decision to make will be if cover it or not. Definitely use a good one pool cover will allow you to protect the tank even better, avoiding the thermal shockthe high and consequent damages.

Furthermore, unpleasant deposits of dirt on the bottom will be avoided.

Not to mention that I don’t use a pool towel it means having to keep the filtration system active throughout the winter, which is definitely to be avoided if the climate tends to be particularly cold in the bad season.

Not to mention the energy expenditure that this entails: a factor to be taken seriously into consideration, especially in the face of the increasingly pressing price increases on domestic users.

How to close the pool: preliminary operations

When proceeding with the closed in winter with a pool towel, it is necessary to take into account some fundamental steps, parameters that must be respected in order for the result to be perfect. The first is that the water must be clear, free of algae and with a completely clean bottom.

This is because the dirt during the winter would have time to penetrate into the PVC, the material of which the pool is made, staining it in a way that is then difficult to clean, and the water would end up being cloudy. In short, a swimming pool must be thoroughly cleaned before closing.

Secondly, you will have to keep an eye on the PH or the acidity rate, which must be between 7 and 7.6. Chlorine is also a parameter to keep an eye on: it must be between one and 1.5 ppm. Finally, it will be necessary to clean the filter thoroughly before removing it or putting it to rest.

This is so that during the winter it does not accumulate limescale or encrustations, which reduce its efficiency. But also to be able to reuse the sand that composes it.

The pool cover

At this point it is essential to switch to the pool cover.

You will need to use a pool towel winter type, which must have pitches of about 1 meter per side, so as to be able to guarantee its anchoring to the edge and thus make it stable.

This operation will obviously be different depending on whether you need to cover an inground pool or an above ground pool.

In the first case, for example, sausages filled with water or sand are very useful, which hold it firmly at the edges while in the second case, cables or elastic rods are the ideal choice.

Choose the types of cover sheets

Of course the pool covers they can be of different types.
There is the non-airtight sheet, made of a dense net, or the PVC one, which completely isolates the water.

Mesh sheets filter rainwater but prevent leaves from entering.

On the one hand they have the advantage of renewing the pool water, on the other hand they also allow access to dust, pollen, sand, spores, which can lead to the formation of algae. And of course, they let the water get dirty.

The hermetic ones, in PVC, in addition to having a longer duration over time, prevent the formation of algae and the passage of pollutants. They also keep the chemical characteristics of the water unaltered, which will remain clear upon reopening.

Of course, for this to happen, it will be essential to prevent the cover from sinking into the pool due to the accumulation of rainwater.

For this, it will have to be emptied periodically with a submersible pump. Furthermore, when reopening, you must be careful not to let the dirt accumulated on the sheet fall into the pool water

The closing of the swimming pool

Once the water parameters have been estimated and the cloth has been purchased to close it, before the actual coverage, the so-called wintering products or wintering pool.

These are products with very precise dosages, indicated on the instructions, which must be followed to the letter.

Cleaning the pool
Once the wintering product has been added, the filter selector must be placed in the recycle position, so that the water does not remove any encrustations from the filter, which would pour into the tank. The filter will then need to be run for an hour or two before moving on to cleaning the filter system.

Cleaning the filter

The last step will be the maintenance of the filter. This is an operation that allows you to disinfect the sand inside the filtering system.

It will be better to use acid-based disinfectant products, or directly buffered hydrochloric acid, as well as of course an anti-algae product.

These products will be inserted directly into the filter, after having closed all the valves, in order to isolate it from the pool.

Then you will have to drain the water it contains. This will preserve the sand for the following season.

If, on the other hand, you decide to change it, the best thing will be to completely empty the filter, throw the sand, wash it and put it to rest, ready to be used again next year.
