Minor leaks can be fixed with epoxy putty. Apply a 1/2 inch thick layer around the pipe. Silicone tape works well for small leaks at drain joints.

总是 turn off the water supply before starting repairs. This prevents accidental sink use during the process.

For bigger repairs, replace the entire P-trap. Make sure new parts match your existing components. After installation, check all connections for leaks.

Pro tip: If leaks continue after tightening, try a quarter-turn counter-clockwise. This can ensure a proper seal. Check gaskets regularly and replace worn ones to prevent future leaks⁴⁵.
