If a bubbler tube system develops a leak above the liquid level, what alarm would you expect and at what wet well elevation?

• A. Make high water alarm sound - high wet well elevation
• B. Make high water alarm sound - low wet well elevation
• C. Make low water alarm sound - low wet well elevation
• D. Make low water alarm sound - high wet well elevation

Answer: (D)

In a bubbler tube system, the primary function is to measure the water level in the wet well by using pressure sensing. The pressure is transmitted through the bubbler tube, which is submerged in the liquid to be measured. If a leak develops in the system above the liquid level, it can disrupt the pressure being transmitted, resulting in a false reading. When a leak occurs, the pressure in the bubbler tube decreases, leading to a situation where the system interprets this as a lower water level in the wet well. Consequently, an alarm will activate indicating that the water level is lower than it actually is. This alarm typically is a low water alarm because the system is failing to create the proper pressure that correlates with the actual water level. Therefore, if a leak is present above the liquid level, you would expect a low water alarm to sound when the wet well is at a high elevation since the leaking system does not reflect the reality of the water level. This situation presents the operator with an alert to investigate the bubbling tube system and address the leak to ensure accurate readings and proper operation.
