My side garden in Albuquerque, NM that is watered entirely by greywater.
An inside look at the greywater plumbing behind the washing machine.
The plumbing as it exits the house.
Here is one method for installing a greywater system from the washing machine sewer drain pipe to your yard. You’ll need to install a three way valve, One is the intake, one goes to sewer and one goes to greywater. Remember, your washing machine has a small pump so you need not worry too much about gravity.
My maximillion sunflower LOVES greywater! The picture on the left is the beginning of summer and the one on the right is end of summer.
