In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction. It limits the total cumulative angle of pipe fittings before a system requires an access point (cleanout) or must be vented, ensuring proper flow and preventing chronic clogs.

A: Traditional tank water heaters usually last 8–12 years, while tankless units often last 15–20+ years. Q: Should I replace my water heater if it's over 10 years old? A: Often yes. Even if it still works, the risk of leaks and sudden failure increases significantly after 10 years.
