The answer to 'my water heater is leaking' is that there are several common causes for a leaking water heater, including a faulty temperature and pressure (T&P) relief valve, loose connections, a damaged tank, or sediment buildup. Symptoms may include water pooling around the base of the heater, dripping sounds, or reduced hot water supply. To address the issue, you'll need to identify the source of the leak and take appropriate action.
If the leak is coming from the T&P valve or connections, this may be a simple DIY fix. However, if the tank itself is damaged or there is significant sediment buildup, it's best to call a professional plumber to properly inspect and repair the water heater. Attempting to fix a major issue yourself can be risky and lead to further damage or even safety hazards.
