One confusing part. Near the end you mention that the pressure vacuum breaker can operate against backpressure 7:31) and then at 8:22 you mention that the PVB is NOT designed to protect against backpressure. This does not make sense, can you please clarify?
PVB’s are only for backsiphonage and must be installed 12” above all downstream piping. They do not protect against backpressure. They definitely made a mistake by saying that it can protect against backpressure.
If I could make one suggestion, I spent most of the video trying to figure out what illustration the narrator was referring to, you guys could really use a pointer or mouse to help this video out.
Thank you my friend. I am taking plumbing classes at Apex and i appericate your knowledge and hard work on explaining these keys terms so simple.
