I have a question about backflow prevention on dishwashers which we have to report on here in Texas.
Typically I make sure that there is a “hi-loop” on the drain line. I reported the lack of a hi-loop on an inspection and the homeowner had a plumber come look at it. He said that this dishwasher had a built-in hi-loop. Can anyone enlighten me on how to know if a dishwasher does or does not have a hi-loop? I assume it may have to do with the age?!?!?!
