1. Which differences are there between a skimmer and an overflow system?
First of all, visually, with a skimmer system we will see that the water level remains about 15 cm below the pool deck, while with an overflow system the water level reaches the pool deck.
Following the phases described above, in the skimmer system water is recovered through openings placed along the upper part of the pool - precisely the skimmers – conveyed towards the filter through pipes, depurated and re-injected through the inlet fittings.
In the overflow system, instead, water that overcomes the border is collected by perimetric channels and conveyed in a balance tank that has to have such a volume as to guarantee the constant water level at the pool deck level and from here taken towards the filter for the depuration end re-injected always through the inlet fittings.
