Nobody at Lennar seemed to know that there was an issue with a missing air gap in the dishwasher drainage line. So I researched it for them.
Here is the email I sent with information on what the dishwasher drainage line air gap was and why it was important.
According to the article I referenced from the StarTribune:
The high loop or air gap must be used to prevent potential backflow contamination of the dishwasher. Local plumbing codes generally dictate the requirements in your area.
Note: As of the date of this publication, all the Lennar executives went silent and none of the construction repairs were ever made, including the promised replacements of two, improperly installed and defective A/C units causing extensive mold exposure and health issues.
Background and responses from the builder on the dishwasher drainage missing air gap issue
