The nozzle made of brass fits the set with the Supra filter. The nozzle directs the stream of water to tap the filter. The Supra kit therefore has self-cleaning properties.
The flushing nozzle is installed by making a hole in the Supra filter housing. There is a specific place for this. Next, the power supply line from the water system should be connected to the nozzle.
The material (brass) is characterized by anti-corrosion properties, thanks to which it does not fail for many years. It is a very simple solution, and therefore durable.
