Quick Answer
An over-pressurized bladder tank can cause it to burst, leading to a loss of water pressure and potentially catastrophic damage to the surrounding system and other connected equipment. This can result in costly repairs and downtime. Immediate action is necessary to prevent such an event.
Causes of Over-Pressurization
Over-pressurization of a bladder tank typically occurs when the incoming water pressure exceeds the maximum rated pressure of the tank. This can be due to a malfunctioning pressure regulator, a clogged filter, or a sudden surge in water flow. In residential systems, this is often caused by a faulty pressure-reducing valve or an incorrectly sized tank for the given water supply.
Consequences of a Burst Tank
If the bladder tank bursts, it can release a significant amount of water, potentially causing flooding and damage to the surrounding area. The pressure wave generated by the burst tank can also cause damage to nearby pipes and equipment. In severe cases, the pressure wave can even cause structural damage to buildings or other nearby structures.
Prevention and Solution
To prevent over-pressurization, it is essential to regularly inspect and maintain the water pressure system, including the bladder tank, valves, and pipes. This includes checking the pressure gauge and adjusting the regulator as needed. In the event of a burst tank, the system should be shut down immediately, and the damaged components should be replaced or repaired. If the system cannot be repaired on-site, it may be necessary to drain the tank, replace it, and then re-pressurize the system.
