The answer to 'water heater leaking water' is that a leaking water heater is typically caused by a faulty temperature and pressure (T&P) relief valve, corrosion, sediment buildup, or a cracked tank. Symptoms include water on the floor around the heater, lower water pressure, and rust-colored water. Solutions may involve replacing the T&P valve, flushing the tank to remove sediment, or in some cases, replacing the entire water heater. It's important to address a leaking water heater promptly to prevent water damage and avoid a more expensive repair down the line.
If the leak is minor, you may be able to DIY the repair. However, for more significant issues or if you're not comfortable working on the water heater, it's best to call a professional HVAC technician to diagnose and fix the problem properly and safely.
