Answers

Do flapper & ball type BWVs provide a 100% positive seal?

Anonymous

No. The ANSI/ASME national standard allows for a minimal amount of seepage around the flapper or ball. The purpose of a flapper or ball is to suppress the back flow. Therefore, if the back flow condition exists over a lengthy period, there will be water seeping into the building at the lowest fixture or floor drain. For a 100% positive seal, you need to specify a figure number 7140 FloodGate ® BWV.
