Southside Virginia is known for moderate to hard water, which causes calcium and magnesium to settle as “scale” at the bottom of your tank. This sediment acts as a barrier, forcing your burner or heating element to work longer, which significantly increases your monthly energy bill and can lead to the “popping” or “rumbling” sounds common in local units.
Definitely don’t plug it! That’s your Temperature and Pressure (T&P) relief valve. It’s designed to leak if the pressure inside gets too high—it’s a safety feature. If it’s dripping, it either means your heater is running too hot or the valve itself has just worn out. Either way, it’s something you want a pro to look at so that a small drip doesn’t turn into a flooded basement.
If you have an electric heater, you likely have a “burnt-out” lower heating element. Your heater has two elements—the top one provides that initial burst of heat, but the bottom one does the heavy lifting to keep the whole tank hot. When the bottom one fails, the water stays “just okay” but never gets hot enough for a good shower. Replacing an element is a quick, routine fix that saves you from replacing the entire system.
