Hello all, I would like to know if it is normal for water to sprout out from the sprinkler valve vent when shutting off. I have a combination of rainbird 075-ASVF and DAS/ASVF-075 valves recently installed. (not sure if it is 3/4" or 1") But I have noticed it is not happening to the DAS/ASVF-075 valves (water not sprouting out from the sprinkler valve vent when shutting off, but causing some banging noise on the pipe. These two DAS/ASVF-075 valves locations are in the back yard and those 075-ASVF are in the front yard. My next question is that are the differences in the models of the valves are causing noise to the pipe or because water is not sprouting out from the DAS/ASVF-075 valves are the cause for the noise. And should water be sprouting out from all sprinkler valve vents? Please advise.
