What should you check first when addressing a leak in a water system?

When addressing a leak in a water system, the first step should be to inspect the joints and fittings. This is because leaks often occur at these connection points where two sections of pipe meet. These areas are prone to wear and may become loose or defective over time due to pressure fluctuations, temperature changes, or improper installation. By focusing on the joints and fittings initially, you can quickly identify and potentially resolve the issue without wasting time on other components that are less likely to be the source of the leak.

While checking the pressure gauge, water meter, or main valve can provide useful information about the system's performance and overall health, these components typically do not experience leaks as frequently as the joints and fittings do. Addressing potential leaks at the joints and fittings first is a practical and efficient approach within the troubleshooting process.
