Troubleshooting
Symptom
Solution
Valve won’t shut off
completely.
Sprinklers “weep.”
Valve won’t open.
Valve slams on / off
(water hammer).
Tighten the solenoid completely (¼ turn beyond hand tight). Use the solenoid handle, which
is specifically designed to shut the valve off completely and keep it from “weeping.” Also
tighten the bleed screw and bonnet screws.
Use the external bleed screw to flush the valve. If performance does not improve,
turn off water. Unscrew bonnet screws and remove bonnet. Remove diaphragm and clean it
in clear water. Reinstall diaphragm and bonnet. If necessary, replace the diaphragm with kit
number 210746-03.
Check water source, controller power, and flow control to make sure they are open.
Turn off water. Unscrew bonnet screws and remove bonnet. Inspect body for debris. If filter is
missing from diaphragm, replace diaphragm with kit number 210746-03.
Turn off water. Remove solenoid and replace with a known working solenoid. If the valve still
won’t open, replace the solenoid.
Check system water pressure. If pressure is greater than 80 psi (5,5 Bars), install a
pressure regulator on the line before the valve to reduce water pressure.
GB

DV/DVF male x male (MM) and male x barb (MB) are not recommended
for flows exceeding 30 GPM (6,8 m
3
/h or 1,9 I/s).
2
For flows below 3 GPM (0,75 m
3
/h or 0,21 I/s), or any Landscape Drip
application, use RBY-100-200MX filter installed upstream.
NOTE
: During winter shutdown, drain the system to protect DV valves
from freezing. Failure to properly drain lines may damage the
valves. Be sure to comply with all local guidelines.
