The answer to 'lifespan of P-trap' is that a properly installed P-trap should last for many years, typically 10-20 years or more with normal use. P-traps are an essential plumbing component that create a water seal to prevent sewer gases from entering the home. They are durable and designed to withstand regular use and occasional clogs without needing replacement.
However, P-traps can become damaged or develop leaks over time due to factors like corrosion, physical impact, or changes in the plumbing system. Homeowners should periodically inspect their P-traps for signs of wear and replace them if any issues are found. Proper maintenance and prompt repair of any problems can help maximize the lifespan of a P-trap.
