Talk:Vacuum breaker

Typically a part that is fairly necessary and helps not allow any unwanted contamination back into your homes, restaurants, etc.

Cost?
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) 20:58, 15 April 2023 (UTC) JdelaF (talk) 20:58, 15 April 2023 (UTC)
