Installation
Make sure the valve is installed according to the flow indication arrow that
has been cast into the valve body. The most common installation allows for a
1/4” IPS nipple between the valve and the water supply being measured. This
ensures there will be adequate spacing for the sprinkler system gauge from the
riser. Use either PTFE Pipe Thread Sealing Tape or a suitable pipe thread
sealant when installing the valve.
CAUTION: DO NOT OVERTIGHTEN THREADS.
OVERTIGHTENING MAY CAUSE VALVE FAILURE.
