When it rains, it pours; and when it pours on your outdoor containment unit, you could have a big problem. Weather the storm with the Bazooka trickle filter/automatic shut-off valve. It allows water to trickle out of your containment berm sump at a rate of 20 gallons per hour while absorbing hydrocarbons. Also compatible with rigid secondary containment units, the unit automatically stops the flow of any liquid once 2 liters of hydrocarbons have been absorbed. The valve is replaceable through a threaded union and easily maintained or retrofitted. You can’t predict the weather, but you can prepare for it with the Bazooka Trickle Filter.
