Plastic spray nozzles are prone to nozzle deformation caused by material creep after prolonged use, whereas the yield strength of 304 stainless steel ensures the aperture remains stable. However, the weight of the metal assembly (0.5 kg) necessitates a mounting bracket with a higher load-bearing capacity. The threaded connection features a rubber coating that ensures a tight seal while preventing electrochemical corrosion caused by direct metal-to-metal contact-a composite design that is particularly important in areas with hard water.
Key factors to evaluate include: 1) whether the inlet water pressure aligns with the system's design thresholds; 2) the long-term impact of water hardness on metal components; 3) whether the mounting surface's load-bearing capacity is adequate for the weight of the metal unit; and 4) the effect of the air-to-water mixing ratio on user comfort. In older residential complexes with low water pressure, a booster pump is required, while residents on upper floors should verify the residual pipeline pressure.
