yes, except the vault was not heated. The PIV is in the vault. We inherited
this problem. We reset the dry valve, then one person goes outside and
opens the PIV, while the inside man watches the dry valve and gauges. It is
a real time waster, but has been that way for years. I do not know if that
arrangement does or does not meet code, the system was installed sometime in
the 1970s.

Subject: Dry pipe control valve
Has anyone ever used a PIV in a hot box in the yard as the control valve for
a dry pipe system. It was my understanding that you needed a control valve
on the actual riser (this by looking at the diagram at 8.15.1.1). Is there
something that says that you can use the PIV as the control. Keep in mind
this is using the 2002 13 code.
