This is an extremely corrosion-resistant faucet that does not rust because it is made of brass and the surface is chrome-plated so that it looks like new even after prolonged use.If the water flow is slightly inclined, you do not have to reach under the faucet when cleaning, so that there is enough cleaning room.The bubbler at the water outlet makes the water flow quieter, does not generate noise and does not inject a large amount of water, which can save up to 30% of the water volume.We also provide manuals, no tools are needed, it only takes ten minutes and it can be installed manually. We also promise you a 3-year warranty.
