If the drain below a Flood Eliminator fails, the dry valve will open, resulting in pressurized water entering the system flowing towards the break. When this high velocity pressurized flow reaches the internal mechanism of the Flood Eliminator, it will shut down the flow eliminating the damaging flooding that would result from a broken free flowing sprinkler line.
The Model 5900FE can be easily retrofitted onto existing auxiliary drains and is designed to be installed above the first valve of a traditional drum drip assembly in a vertical position. It will be necessary to close the dry valve and remove the drum drip assembly for installation. Since the 5900FE is only 3 ½” long it will likely be unnecessary to shorten or remove existing pipe. Old thread sealant should be removed from any pipe thread and from the drum drip valve and appropriate new sealant should be applied to all connection points. The 5900FE needs to be installed vertically in the direction indicated on the body.
