How often should a plumbing inspection be performed in residential systems?

Performing a plumbing inspection at least once every 3 years is considered best practice for maintaining residential plumbing systems. Regular inspections help ensure that potential problems are identified early before they develop into more significant issues. Over time, plumbing systems can experience wear and degradation due to factors such as corrosion, sediment buildup, or even tree root intrusion into drainage lines. By adhering to this inspection schedule, homeowners can maintain efficiency, prevent costly repairs, and ensure the safety of their water supply.

This frequency strikes a balance between being proactive in maintenance while not being overly burdensome for the homeowner. It’s a reasonable interval that allows for monitoring the system's overall condition, leading to enhanced longevity and functionality of plumbing installations. Regular inspections also contribute to compliance with local codes and standards, which can be particularly important when planning future renovations or sales of the property.
