Valves

In some greywater plumbing systems the greywater  3-way valve may need to be installed in inaccessible location, or the user may not want to have to go outside/under the house to switch the 3-way valve. A 3-way valve actuator can be mounted on top of the 3-way valve and connected to a switch installed inside the building to control the valve. The 3-Way Valve Actuator Switch Kit includes all the items need to install a switched actuator on a 3-way valve. The kit includes:

The 3-Way Actuator is used to automate the switching of a 3-way valve on the greywater plumbing system. The 3-way Diverter Valve used for greywater systems is manually controlled by turning the handle on top of the valve. In some situations the 3-way valve may need to be installed in inaccessible location, or the user does not want to have to go outside/under the house to switch the valve.

The Pentair 3-way valve allows you to simply change the flow of your greywater; to the greywater system OR to the sewer system. The 3-way valve can be automated or mechanized by mounting a Goldline actuator on top of the valve to allow remote switching of the greywater system. The 3-way valve accepts both 2" or 1.5" drain pipe and the 3-way valve can be plumbed with any port as the inlet.

The Auto-vent or Air Admittance Valve allows air to enter into the laundry to landscape greywater system but doesn't allow water to exit. It is used to prevent a siphon from sucking water out of the machine as it tries to refill. To connect this piece to the rest of the system you will need a 1 1/2" threaded female adapter, and a 1 1/2" x 1" bushing.

Note: This valve is not connected to the drainage plumbing of the house, and is not being used as a vent.

The Brass 1" 3-way Valve is used in laundry to landscape greywater systems to switch between the greywater and the sewer or septic system. It is threaded with female pipe threads, and the inlet is always in the middle of the tee.  We source "full-port" valves that do not constrict the flow of water through the valve.

The Green Back Valve Barbed 1/2" is used to adjust the flow from greywater outlets. For unfiltered greywater, this is a point of potential clogging and should be monitored. Green back valves have a larger orifice than typical ball valves and are the only brand we've found that work with the laundry to landscape system (other brands clog very quickly).

The Green Back Valve Barbed 1" is used to control the outflow of a 1 inch line, or to shut off a 1 inch branch. In a laundry to landscape system do not use these on all the ends or branches, one end must always be left unrestricted to allow for the full flow to exit the line.
