There are a few plumbing issues that you can take care of yourself, such as unclogging a drain with a plunger, fixing a leaky faucet, or replacing a showerhead. However, for more complex plumbing problems or if you're unsure about how to handle a particular issue, it's best to call a professional plumber. Attempting to fix a plumbing problem without the proper knowledge or tools can lead to further damage and costly repairs.
