The answer to 'how to maintain pipe' is to regularly inspect, clean, and protect your home's plumbing system. This involves checking for leaks, clearing clogs, and taking steps to prevent future issues.
Start by visually inspecting all exposed pipes for signs of corrosion, cracks, or leaks. Listen for any unusual noises that could indicate a problem. Use a plunger or drain snake to clear any slow-draining sinks or tubs. Additionally, treat your pipes with a chemical cleaner every 6-12 months to help dissolve buildup and prevent clogs.
