Flout stands for “Floating Outlet.” It is a new way to flood septic system effluent into the leach field. It floods the distribution box with water well above the invert of the leach pipes and insures an equal, fast flow of water down all legs of the leach field.
What does it do exactly?
The Flout Systems holds back the water coming from the septic tank until enough is collected to flood the leach field. When the discharge cycle starts, all the stored water is fed to the distribution box and flows out every leg of the leach field.
After discharging is complete, the septic tank water is held back until another full charge of water is collected. This gives the leach field time to rest and absorb the water that has flooded it.
The flooding action insures the entire leach field sees water every time the tank discharges utilizing more surface area of the soil to treat the septic effluent than that of a standard trickling leaching system.
How does it work?
As effluent from the septic tank fills the chamber, the Float is empty and buoyant and floats on the surface. Flexible connectors allow the Float to rise. When the effluent reaches the maximum level in the chamber, it spills into a hole in the top of the float; this causes the float to sink.
The effluent in the chamber discharges through the pipe(s) which exit the Float, dosing the septic field while providing equal distribution through each outlet. The chamber continues to empty down to the top of the Float. Then the Float empties and resumes floating to repeat another cycle.
What makes the Flout better than a Bell Siphon? It is easier and faster to install than a bell siphon and requires no special forms to build. Handling and onsite installation is accomplished using the same equipment required to set a septic tank and all work is done at the same time the septic tank is delivered. The Flout tank can be leveled quickly and accurately. Any of our precast septic tanks can be easily modified on short notice to accept a Flout to suit most any needs for a dosing tank. A contractor can install the Flout tank in about an hour and wastes no time leveling the outlets of a distribution box. The Flout is glued in place inside the dousing tank (at the precast plant) and delivered ready to install in the ground. The excavated hole for the tank requires a simple flat bottom. 3" or 4" adapter connection pipes can be cast or cut into the tank wall, as per customer requirements and connection to the distribution box is by the installation contractor. No more "grouting in" bell siphons on the job site. No priming water ever needs to be added to the Flout for correct operation. Connection to the distribution box is just as easy as gluing PVC pipes together. For those big jobs, any number of outlets may be installed in the tank, even or odd number as required. For large dousing applications, additional holding tanks can be paralleled to the dousing tank increasing water, volume per discharge.
