Record the static water supply pressure.
Open the main drain and allow water flow to stabilize.
Record the residual water supply pressure.
Close the main drain (slowly).
DRY PIPE PRIMING LEVEL
Check dry valve priming water level by opening the test valve and checking for a small
amount of water to discharge. If no water flow out of the test line, add priming water.
ORIGINAL WATER PRESSURE
STATIC PRESSURE
Record the static water pressure as noted on the lower pressure gauge.
RESIDUAL PRESSURE
Record the residual water pressure (water flowing from the 2-inch main drain) as noted on
the lower pressure gauge.
