3Way Diverter Valve
Your washing machine outlet hose should connect to this three way diverter valve which inturn will either connect to the sewer or to the landscape to be watered with greywater. The days that you use bleach or other chemicals you can direct the water to the sewer.
Autovent or AAV
Installed at a high point, prevents potential siphoning of water from the washing machine
Irrigation Valve Box
Each outlet is dicharged into a mulch shield with an irrigation valve box
Purple Stripe Piping
1 inch PVC pipe (purple striped piping): Purple indicates grey water
Mulch
Use ordinary mulch obtained from your garden store around the irrigation valve
Anti-Siphon
This prevents back flow of water back into the washing machine
