The answer to 'P-trap replacement frequency' is that P-traps typically need to be replaced every 5-10 years, depending on usage and water quality. P-traps are the curved pipe under sinks that catch debris and prevent sewer gases from entering the home. Over time, they can become clogged, cracked, or corroded, requiring replacement to maintain proper drainage and prevent plumbing issues.
Factors that can affect P-trap lifespan include the type of material (plastic vs. metal), frequency of use, and water hardness. Homes with higher water usage or hard water may need to replace P-traps more often. Homeowners should inspect their P-traps periodically and replace them if they show signs of wear or leaks.
