The quality of water in the pool depends largely on the circulation system (the method of water intake and supply to the pool). - Return nozzles - serve to return the already treated water back to the pool. They are usually placed opposite the skimmer or in places where it is necessary to circulate the pool water. The nozzles must be set to circulate the entire pool volume and prevent the formation of so-called "dead spots". The nozzles are made of steel or plastic materials. - Suction nozzle - used for connecting the vacuum hose. Material STAINLESS STEEL: does not undergo changes due to chemical or atmospheric influences.
