There are several signs that your water heater may need replacing. If you’re experiencing inconsistent water temperatures, hearing unusual noises such as banging or rumbling, noticing leaks around the unit, or seeing rust-colored water, it may be time for a replacement. Additionally, water heaters typically last 10-15 years; if yours is nearing or beyond that age, upgrading to a newer, more efficient model can save you money and ensure reliable performance.
