Installing new fixtures involves replacing or adding items like light fixtures, faucets, or sinks in a home. This process typically requires basic tools such as a screwdriver, pliers, and a wrench. Before starting, it's important to turn off the power or water supply to ensure safety. Once the old fixture is removed, the new one can be installed by following the manufacturer's instructions. This may include connecting wires for electrical fixtures or securing plumbing for water fixtures. After installation, it's essential to test the new fixture to ensure it functions properly and does not leak.
