Existing system is dry.
owner installed heating in building.
Question: Is there advantage to just changing it to wet (taking out DPV
and installing a piece of pipe with a flow switch)?
System does have a backflow valve installed.
My initial thought was that the owner would save costs associated with
annual trip testing of the DPV, draining of the low point drains, etc.
