A pool nozzle is a device to which pool cleaning equipment is connected, placed on the pool walls and connected to a pumped vacuum line. The nozzle outlet ends are opened when the pool cleaning equipment is to be used and kept in the closed position when the pool is in use.
The pool nozzle differs according to the size of the pool and the number of cleaning tools to be used. There is a hiding cover on the pool nozzle, which is generally made of hard plastic.
The pool nozzle used in in-pool cleaning serves as removable and attachable apparatus where the connections of the pool equipment are made. Pool nozzle is an auxiliary element during the use of pool vacuum cleaner, pool robot and other cleaning machines.
Many different tools are used in the cleaning and maintenance of pools. It is possible to provide the connection system necessary for the cleaning equipment to be used easily at every point in the pool with a pool nozzle. The pool nozzle, which is a practical connection tool, is mostly available with 2 threads and works at a minimum flow rate of 7000. 
Types of pool nozzles:
Available in various brands and models, the stainless nozzle is not affected by the chemicals in the pool water. The long-lasting and durable stainless nozzle is also protected against abrasion. The non-clogging stainless nozzle model, which can be used in indoor and outdoor swimming pools, is an affordable pool equipment.
Pool vacuum nozzle is a type of nozzle to which pool vacuum cleaners are usually connected. Vacuum nozzles on pool curtain walls are resistant to high and low temperatures. The vacuum nozzle, which is fixed to the pool wall by gluing, has 2 connections.
The overflow nozzle used in overflow pools is fixed to the pool wall like other nozzle types. The overflow nozzle with PVC body is resistant to pool water. The overflow nozzle is used with pipe connection suitable for 75 bar and 90 bar pressure of cleaning equipment.
The jet nozzle model is a preferred pool connection tool for large and large-sized pools. Jet nozzles, which can be used especially at high flow rates, are resistant to deformation and strong. Jet nozzle is one of the nozzle types that are effective in the connection of pool robots.
The pool nozzle is determined according to the pool dimensions and pool type and mounted on the pool walls. The preferred pool equipment for pool cleaning is connected to the connection tool, that is, the pool nozzle. The most preferred pool nozzle type is vacuum nozzle. The pool nozzle, which provides connection with the outlet ends, is very easy to use.
The pool nozzle can be used in certain types of pools. For example
The number of nozzles increases or decreases according to the depth and size of the pool. For swimming pools with a depth of more than 1.35 cm, one pool nozzle can be added per 8 m². For swimming pools with a depth of less than 1.35 cm, one pool nozzle per 6 m² is used.
It is also possible to determine the number of pool nozzles according to the flow rate calculation. By dividing the square meter of the pool and the flow rate, the number of nozzles required in the pool is learned.
