Localized fire is the most common cause of tank ruptures.

However the most common cause of PRD failures is the simple problem of water getting into the outlet lines of the device. Emcara resolved this problem by developing a complementary vent cap. The vent cap ensures that water does not enter the outlet lines and reduces the number of components required in the current setup, therefore reducing overall cost to the customer.
