If you've left your pool unused for several years, the structure is likely in an advanced state of disrepair, making it unusable. Therefore, you'll need to carry out a series of necessary actions to be able to use it again.

Restore the old swimming pool

Check that the electrical panel is in good condition. If the system has a salt chlorinator, you must examine both the electrical panel and the cell.

Avoid starting the filtration pump if it hasn't been used for several years. If you don't want to buy a new one, you should dismantle the pump house and its components, check their condition, carry out any necessary repairs, and clean each part inside and out. Seek professional help from an electrician to check that the pump isn't making any unusual noises and that the fan blades are functioning correctly.

Use a leaf skimmer to remove larger debris floating in the water (leaves, insects, sticks, etc.). 

Brush the walls of the water glass with a hand brush or sponge to remove any dirt stuck to the lining. If the glass is empty, use a hose to help remove the dirt.

Vacuum the debris from the bottom of the pool using a pool cleaner  (manual, hydraulic, or electric). The use of these cleaning robots is recommended for pool maintenance, so it's necessary to manually clean the pool basin before using a pool cleaner to prevent premature wear and tear on the equipment.

Once the pool is clean, check for any damage to the pool shell and other components. Take this opportunity to make any necessary repairs. 

In pools tiled with mosaic tiles, it's very likely that some pieces have fallen off or broken, so you should pay special attention to this type of lining. In these cases, we recommend grouting the joints, as this will prevent the growth of algae and other microorganisms.

Over time and due to inclement weather, the other pool accessories (skimmer, lights, jet nozzles, drain, etc.) will experience significant wear and tear that will require the replacement of the trim.

Abandoned swimming pool

In the first few days after restoring an old pool, you should be on the lookout for any leaks in the pool shell. One of the most obvious signs is that the water level always remains below a specific point. 

However, water loss can also occur due to damage to the water circuit pipes, which are caused by reasons as varied as ground movements or having placed chlorine tablets in the pool skimmers.

If you are unable to raise the water level due to evaporation caused by high ambient temperatures, we advise you to use a thermal blanket to cover the pool water and reduce evaporation.
