Petroleum Filter Valves for Secondary Containment

Adding an oil water separator to your secondary containment systems is a best management practice that saves your technicians hours of time. It also helps prevent unintended releases caused by drain valves being left open after draining systems following a storm. Drainiac^® Petroleum Filter Valves are self-contained oil water separators that capture oil and petroleum while allowing clean water to filter through. They close off to prevent oil discharges when they have reached their oil-absorbing capacity.
