What would happen if the vent on the ground storage tank is clogged while the tank is being filled?

• A. The anodes would dissipate
• B. Pressure would decrease
• C. The tank would fill up with pressure
• D. Tuberculation would become a problem

Answer: (C)

When the vent on the ground storage tank is clogged while the tank is being filled, the tank will fill up with pressure. This occurs because as water flows into the tank, the air inside needs to escape. If the vent is blocked, the air cannot exit, creating a vacuum effect where the air cannot equalize with the incoming water. Consequently, as the tank fills, the pressure inside increases, potentially leading to structural issues or even causing the tank to rupture if the pressure exceeds the tank's design limits. The design of tanks includes vents specifically to avoid this situation, allowing air to escape and maintaining proper atmospheric pressure inside the tank. This helps to ensure the tank can fill and empty correctly without compromising its integrity.
