What are the best practices for installing a washing machine standpipe to ensure proper drainage and prevent potential leaks or flooding?

When installing a washing machine standpipe, make sure it is at least 18 inches high and no more than 30 inches high. Use a P-trap to prevent sewer gas from entering the home. Ensure the standpipe is securely fastened to the wall and that the drain hose is properly inserted to prevent leaks. Regularly check for clogs and ensure the standpipe is properly vented to prevent flooding.
