A plumbing inspection should always include which of the following actions regarding faucets?

The process of a plumbing inspection should include testing for leaks, as this is a crucial aspect of ensuring the integrity and functionality of the plumbing system. Leaks can lead to major issues such as water damage, mold growth, and increased water bills. During an inspection, examining faucets for any signs of dripping or water accumulation around the base is essential to identify potential problems that might not be visible at first glance. Testing for leaks also allows for timely repairs which can prevent further damage and maintain efficient water use.

While replacing old faucets may sometimes be necessary, it is not a standard procedure applicable in every inspection. Fully disassembling faucets could lead to more issues if they are not reassembled correctly, and painting faucets is generally not within the scope of a plumbing inspection, as it does not contribute to assessing their operational state. Thus, testing for leaks is the appropriate action to include in an inspection of faucets.
