“The hose from the washing machine is connected to a 3-way valve.
This allows the greywater to be diverted to either the sewer/septic, or the greywater system. Labeling the valve is important so anyone using the system will know where they are sending the greywater.
A 1 1/2 inch hole is drilled into the side of the house so the 1 inch PVC pipe can exit.
Before drilling careful attention is made to ensure the hole will not damage electrical wires, water pipes, or structural features of the building. The hole is sealed from the outside to prevent moisture, air, or bugs from getting into the house.
The auto vent must be installed at the high point of the greywater line!
It prevents accidental siphoning of water from the washing machine…”
