Does anyone think that having some flow diagrams here would help clarify the different operating modes (eg normal, backflow, backflow leakage, etc.). Seems I am starting the first comment here, but I will check on my own in my engineering textbooks to see if I can find anything that would helpful in this case.-- Ivangiesen ( talk) 12:54, 15 June 2020 (UTC)
Why so much variation in cost of vacuum breaker/backflow preventers (eg $3-35)? Which type is needed for home/yard use? Is freeze-resistance important? JdelaF ( talk) 21:00, 15 April 2023 (UTC) JdelaF ( talk) 21:00, 15 April 2023 (UTC)
