The answer to 'water heater leaking water' is that a leaking water heater is a common problem that can be caused by a variety of issues, including a faulty temperature and pressure (T&P) relief valve, a cracked tank, or sediment buildup. Symptoms may include water pooling around the base of the heater, water dripping from the T&P valve, or reduced hot water supply.
In many cases, a leaking water heater can be repaired by a DIY homeowner. Simple fixes like replacing the T&P valve or flushing the tank to remove sediment may resolve the issue. However, if the tank itself is cracked or the leak is severe, it's best to call in a professional HVAC technician to evaluate the problem and determine if the water heater needs to be replaced.
