What is backpressure in water?
Backpressure is essentially when the contaminated water or liquids are pushed back into the potable water system due to an increase in water pressure. Two ways this can happen are by mechanical means, where one system is connected to another system with higher pressure, like elevated piping or a booster pump. Another way this can happen is due to thermal expansion caused by a boiler or water heater that has malfunctioned. Backpressure is considered direct contamination.
