SETTING THE SYSTEM PRESSURE
The 110410 Woodpecker drippers (below) require a minimum of 7 psi for operation. Operating pressure range is 7 psi to 45 psi.
To prevent damage to the
drippers, do not exceed 45 psi.
After checking the system and ensuring that all components are functioning, check the pressure. Pressure can be increased or decreased by opening and
closing the WF3316 ball valves. Pressures for each bank of Dutch buckets should be similar. Adjust ball valves to change the pressure and bypass flow.
REMEMBER:
Valves work together. Adjust as needed to get the desired system operating psi and bypass flow. Mark valve positions if desired to reset after
performing system maintenance.

Valves A:
Use these valves to isolate either side of the
system during routine maintenance, cleaning, and changing
filters. They can also be used to take either side of the
system out of production.
Valves B:
Use these valves to control pressure. For best results, valves
should remain at least half open. This maximizes aeration and flow to the
reservoir to stir settled nutrients and keeps the psi within the desired range
of drippers. Recommended operating system pressure is 10-20 psi. Adjust
as needed to achieve this range.
ATTENTION:
Actual tank may differ
from the example shown.
