I go until it's misting. I typically wait when it's still spuddering water every 2 seconds until maybe every 4-5 second spudder. Depending on the design of the zone sometimes you could blow that thing for 10 min and still not get all the water out ( Not that i've done this ) Water could easily collect at a low spot and break things.. Particularly on sams, it's a shame to replace a 12" sam from freeze damage after it was winterized.

The biggest thing is.. It's not worth the argument or the huge verbal description to the customer when they are outside with me when I can just wait an extra 30 seconds. The customer doesn't know but if they see the water and I say it's done when it is they may or may not believe me. Then I have to explain my self which can be annoying. Id rather BS with the customer building a CR rather then giving them a possibility of worrying that i'm not doing the job correctly. Most of the time it's not a big deal, everyonce in a while you get someone who will not believe the water is out no matter what. For them I say Stick you hand right here!

A lot of times I will go back through each zone for a few seconds.. I firmly believe water gets pushed back and forth throughout the system main line while switching zones and as well when the zone stops water that wasn't blown out will collect at a low spot that will get blown out. Again this is still all within a typical 1-3 min run time per zone
