Cut your secondary containment stormwater discharge costs in half. A secondary containment filter valve that automatically shuts off in case of an accidental spill.

Discover the cost-effective way to stay ahead of sheen water inside of your secondary containment. Filter media automatically swells up and shuts off in case of an accidental spill. Perfect for outdoor, above-ground secondary containment.

Stay in SPCC compliance. Implement as a Stormwater SWPPP Best Management Practice (BMP). Available in the following sizes:

SPL101: 3.5” Diameter x 5.5”L
56.6 gallons per hour flow rate measured while draining from 2” to 1” of head pressure
SPL101-.75MIPT: 3.5″ Diameter x 5.5″L with .75 MIPT Fitting
(Replacement filter valve for portable containment)
56.6 gallons per hour flow rate measured while draining from 2” to 1” of head pressure
SPL103: 6.5” Diameter x 8”L
387 gallons per hour flow rate measured while draining from 2” to 1” of head pressure

Description

Do you have any of these problems dealing with stormwater in secondary containment?

Wasting time manually draining stormwater?
Forgetting to close drain valves?
Hiring expensive vac trucks to haul and dispose of oily sheen water?
Replacing existing, expensive filter valves that are clogged with sediment?
Algae buildup inside containment?
Frozen containment floors in the winter?

Fortunately, there is a better way. The Drainiac^® Petroleum Filter Valve.

A patented secondary containment filter valve that:

Filters Oil & Fuel: Allows stormwater to drain from your secondary containment system while effectively filtering oily sheen.
Captures Sediment: The Drainiac^® Pre-Filter System (not included) captures sediment before it clogs your expensive filter valve.
Two pre-filter options, based on your application:
- Above-Ground Secondary Containment: Above-Ground Drainiac^® Pre-filter System
- Under-Ground Sumps: Drainiac^® Husky Pre-Filter Sediment Jacket
Prevents Spills: Automatically swells up and shuts off. Prevents a catastrophic oil or fuel spill from escaping your secondary containment.
Saves Money: Eliminates the high cost to pump, haul, and dispose of contaminated secondary containment water.
Minimize your “Headache Calls”: No oil sheens outside containment. No overflowing containment. No vac trucks.
Drains 4x Faster than other “similar” products.
Prevent Tripping Hazards: 400% smaller than “similar” products.
Lasts up to 10x Longer: Pre-Filter System prevents the system from prematurely clogging with silt, sediment, and debris.

Product Specifications

Flow Rate: While all other manufacturers measure their flow rates at a constant 2” head pressure, we measure ours based on what is happening in the real world.

Cutoff Loss: Other manufacturers allow various amounts of petroleum to pass through their valves before complete shut off. The Drainiac Petroleum Filter Valve System is engineered to not allow any petroleum products to escape. Therefore, there is no loss.
