Manufactured from polypropylene geotextile, the Drain Warden is an excellent hydrocarbon and solids filter. Virtually impossible to block with overflow holes at the top of the unit.

To determine if the Drain Warden needs replacement, inspect directly after a rain event. If it is holding water, the filter is blocked and requires replacement.

To install, simply remove the drain grate, position the Drain Warden and replace the grate. Once the ties have been secured and the excess material cut off, the unit is operation.
