Test the main shutoff valve annually so it turns freely when needed. Avoid pouring grease or coffee grounds down drains, and use drain screens to catch hair. If your home has copper in older homes, PEX dominant in post-1980 construction, consider periodic inspections for corrosion, scale, or movement-related stress.
