SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Need help please,
I have installed the RPZ today and first thing I got is the water come out from the Test Cock#2 strong like a sprinkler head and could not stop it. Not too sure what's happen.
I though this is a test plug having inside ball too seal the water but apparently it was not. I try to figure out why then fix it before call the supplier. You know it come from mail order, it hard to return.
Also, I realize a screw at each of the test cock but unsure what is it for?
Any one know about this Watts 1" 009 QT model please help. There is nothing connect to the downsteam pipe yet.
Thanks

Thank RLVI,
It took me awhile to figure it out. I took the test cock out of the main housing, both the good one and the "trouble" one. Play around with it trying to compare the diferrent, then reallize that the manufacture worker has forgot to close the valve before ship it.
It scare the new bee like me a little while, unfortunately. After that problem, I ran into another. The copper pipe connection between main line into the backflow kept leaking. A few trip back and forth to Home Depot. There is a lot of confusion how to use the seal white tape. One person told me need four turn of tape then hand tight. The other said only one turn. The prof. plumbing told me tight very strong. I never have problen to seal the small thread size like 1/2 or 3/4 but always have problem w/ the 1". Finally, I bought the teflon compound sealant from HD. With the new teflon compound. It stop the leaking completely. I should use this in the first place. I don't thing I will ever use the seal tape again but like to understand why it not work for me.
Any though how to do or not to do w/ the tape would be appreciated.
Thanks,
Long
