Reattach any cabinetry or fixtures removed during the process. Turn the water supply back on and give your new vent one more test-run. Give the area a thorough clean, and preserve documentation of the new installation for future reference or inspections. Once you have reattached the cabinetry or fixtures, it is important to double-check that they are secure and properly aligned.
This will ensure a seamless finish to your installation. After turning the water supply back on, run the vent once more to ensure proper functionality and to address any potential issues immediately. Finally, give the entire area a thorough clean, removing any debris or dust that may have accumulated during the installation process.
