Showerhead (Comfort Wave 1 Mode) Chrome Plated This shower provides both water saving and a moderate stimulating sensation. Lower limit of appropriate flow rate (L/min): 5 Required water pressure for lower limit of appropriate flow rate (Mpa): 0.05 The showerhead is made of plastic. Please be careful not to strip the threads when screwing it in. If the filter becomes clogged, the water flow will decrease, and the function will not be fully realized. Please remove the showerhead occasionally and clean the filter. I am selling this because it came with my home renovation, but I replaced it with a different showerhead. I believe water was run through it for a shower inspection. Please understand and purchase accordingly. I am selling it at a low price, so returns are not accepted.
