How to Install a Greywater System
The following are directions for installing the Flotender Greywater Processor in an instant distribution configuration.
There are four steps in the installation of a Flotender Greywater system:
The actual installation of the Flotender Greywater Processor (step 2) is a straight forward process and can be accomplished within a couple of hours by either the homeowner or landscaper and does not require plumbing expertise. The Flotender Greywater Processor ships 90% pre-assembled and includes straight forward and detailed instructions for the remaining assembly.
1. Separating Greywater Sources
In order for the Flotender Greywater Processor to function correctly, the greywater must be piped separately from the blackwater. In addition a greywater “stub-out” must be installed. The stub-out can be plumbed to a utility room or outside of the building as the Flotender Greywater Processor can be placed either inside our outside of the building. .
2. Installing the Flotender Greywater Processor
Once the greywater stub-out is in place, the greywater processor can be installed. The following features an in-ground installation. Flotender can also be placed above ground or in a utility room.
2-1 Choose a Location
For in-ground greywater processor installations, excavate and place the Flotender Greywater Processor on 1" of compacted sand. Sand will protect the bottom of the tank from sharp objects and help in leveling as you install the greywater processor.
2-2 Connect the Add-On Surge Tanks
Note: If your greywater system does not an add-on surge tank, skip this step.
Place the Flotender Add-On Surge Tank next to the Flotender Greywater Processor as shown in one of the configurations below. For connection details, please refer to the instructions included with the Add-On Surge Tank Connection Kit.
2-3 Connect to Greywater Stub-Out
Connect the Flotender Greywater Processor to the building’s greywater stub-out using the included PVC pipe and flexible coupling.
2-4 Connect the Overflow
Extend the overflow to drain above ground, below ground or to the existing sewer or septic line.
2-5 Connect the Filter Wash System
Connect the 1/2” purple stripe pipe to the side barb on the tee filter for the self-regulating filter wash system and then to the spray ring port on the greywater processor. (see next section for diagram)
2-6 Secondary Filter and Performance Indicator Connections
Install the secondary tee filter, connect the performance indicators, then connect the drip pipe to the barb on the tee filter. Refer to the illustration below:
3. Install the Drip Irrigation System
Use the port on the secondary filter labeled “to drip emitters” to connect the drip irrigation system. Please refer to the specific instructions provided by the drip system’s manufacturer. Flotender is compatible with both above ground and sub-surface drip irrigation.
4. Backfill and Final Tasks
Before backfilling around the Flotender Greywater Processor and piping ensure that the following have been completed:
Servicing the Flotender Greywater Processor
The amount of maintenance required for the greywater filter varies depending on the type of greywater fixtures being installed and the amount that they are utilized. Typical service intervals range from once a month to once every 4 months. If washing machines are to be connected, service intervals will be closer to 1 month. If sinks, showers, bathtubs & sinks are connected the service interval will be closer to 4 months.
Cleaning the Primary Filter
To clean the primary filter, simply open the Access Cap, lift out the basket and wash off the debris.
Cleaning the Secondary Filter
To clean the secondary filter simply unscrew the filter from its casing and clean the element and media with a standard garden hose.
