A » To install a standpipe for a washing machine, first ensure the standpipe is at least 2 inches in diameter and extends 18-30 inches above the trap. Connect the standpipe to the existing drain line using a sanitary tee fitting. Secure the pipe with brackets for stability. Ensure the trap is vented to prevent siphoning. Finally, test for leaks by running water through the system.
