Here, the manufacturer of Stainless Steel Faucets will share the reasons for the faucet dripping:

1. Causes of water leakage at the water outlet
   That's because the shaft gasket in the faucet is worn. Use pliers to loosen and remove the gland bolt, take out the shaft gasket with a clip, and replace it with a new shaft gasket.
2. The reason for the leakage of the gap in the lower part of the faucet
   That is caused by the wear of the triangular seal in the gland. You can loosen the screw to remove the bolt head, then loosen the gland, then remove the triangle seal shop inside the gland and replace it with a new one.
3. Water leakage at the joint
   Generally speaking, the cap nut is loose, then you can re-tighten the cap nut or replace it with a new U-shaped gasket.
