Drain pipes have a finite lifespan based on the materials they're made out of. Copper can usually last between 70 to 80 years, while plastic, Galvanized, and Iron pipes may only last 25 to 40 years. Depending on how old your home is and when the pipes were installed, you might need to replace them when things start going awry.
When you notice problems with your pipes, it's time to call a reputable company, like Mike Diamond, to examine them and determine whether it's safe to repair them or if they need to be replaced. Replacing pipes is sometimes recommended, such as if they're too corroded or if you happen to still have lead pipes in your home.
