Probably, for those who want to buy a pool, it will be interesting what kind of overflow pools, how they work, and how the overflow pools differ from pools with a skimmer.
We decided to sort out the question of what kind of overflow pools they are, and found a very clear explanation.
Overflow pools are a type of pool in which an overflow system is used to draw and circulate water.
When water spills over the side of the pool, it does not spread everywhere, but gets into special overflow trays located around the entire perimeter of the pool bowl. Then the water enters the overflow tank, which is located below the overflow trays.
A pump is installed in the pool system, which pumps water from the overflow tank to the bottom nozzles. At the same time, the water is heated, filtered and undergoes full purification. Through the bottom nozzles, the water again enters the pool.
Overflow pools differ from skimmer pools in that in pools with skimmer water circulation, a skimmer is used to draw water, while overflow pools use special overflow troughs to prevent water from splashing out and transferring it to the system.
Overflow pools will delight in the fact that, thanks to the overflow system, they have one water level even when a large number of swimmers bathe.
Since the contamination strip is located in the return bowl of water, all small particles of dirt get into the special overflow trays, so that the water goes through a complete cleaning cycle, being filtered and receiving complete disinfection. 
Another advantage that such popular overflow pools have is that pollution does not stick to the walls of the overflow pool bowl.
overflow pools, like a skimmer pool, can be made of polypropylene or some other material. The gutters for overflowing water are covered with a special mesh, which fits harmoniously into the design of the pool.
When modeling the pool, the manufacturers themselves choose which materials the mesh for covering the overflow troughs is made of. Many overflow private pools of any size and any form are equipped with the overflow system today.
Also, the overflow pool has a rather spectacular appearance, more reliable regarding water treatment.
It is overflow pools that are chosen by those who value functionality and external grace. Of course, an overflow pool will cost more than a skimmer pool.
Today in the Russian market a lot of companies offer quality overflow pools.
We recommend that you carefully read the accompanying information from the manufacturer, which characterizes the manufacturing technology, the principles of operation of a pool of a particular brand, as well as familiarize yourself in detail with the scheme of the pool with an overflow system and with the information that is included in the overflow pool system so that you can easily understand the nuances of the functioning of the pool.
