What should I do if my water heater is leaking, and how can I quickly ascertain the root cause of this potentially damaging issue? Is it simply a minor nuisance, or could it signal a more profound malfunction that demands immediate attention? First and foremost, should I consider shutting off the water supply to prevent further leakage? Additionally, what steps must I take to assess whether the leak originates from the tank itself or perhaps from the plumbing connections? Are there specific indicators to look for that can help identify the source of the problem? Once I’ve recognized the origin of the leakage, what are my options? Should I attempt to remedy the situation myself, or is it prudent to consult a professional plumber to mitigate any risks? Furthermore, are there preventative measures that can be implemented to avoid similar incidents in the future? How can regular maintenance safeguard against these unforeseen leaks?
