TROUBLESHOOTING GUIDE
Every OPW nozzle is tested on a pump at the factory and is guaranteed to be in proper working condition
when shipped. Its continued proper operation is dependent upon reasonable care in handling. Automatic
nozzles should not be dragged or thrown on the ground or paved surfaces. The automatic shut-off elements
are subject to damage by such handling which can result in failure to shut off properly.
EXPERIENCING LEAKS AT THE INLET
What to check?
√ Check if there is sufficient sealant on the pipe threads.
(See Figure 1)
• Solution: Disconnect and apply proper sealant to the threads.
√ Check the nozzle for proper attachment to the hose.
• Solution: Disconnect the hose from the nozzle, reconnect the hose and tighten. (See Figure 2)
√ Verify that teflon tape was NOT used.
• Note: Use of teflon tape can allow for over tightening which leads to cracked inlet threads.
CONTINUOUSLY LEAKS OUT OF THE SPOUT
What to check?
√ Leaks out spout and doesn’t stop. Debris or foreign objects in the main poppet. (See Figure 3)
• Solution: Replace nozzle.
√ Leaks out spout and slowly stops. There may be debris or foreign object in bleeder poppet.
• Solution: Remove spout and clean debris. Always use new spout kit and/or new o-rings approved by the
manufacturer for replacement. (See Figure 5)
THE NOZZLE DOES NOT SHUT OFF OR SPLASH-BACK OCCURS
What to check?
√ Check the minimum flow rate of nozzle. 11A & 11B Series minimum flow rate is 3 GPM. 7H Series
minimum flow rate is 5 GPM.
• Solution: Improve flow rate. May need to change dispenser filter.
√ Check to see if the nozzle is properly in the fill pipe. Liquid must cover the venturi port on the spout tip
for shut off. (See Figure 4)
• Solution: Reposition nozzle in the fill pipe.
√ Check the spout o-rings to make sure they are not cut or missing. (See Figure 5)
• Solution: Remove the spout to replace o-rings.

LEAKS DURING A FILL
What to check?
√ If the leak is occurring at the lever guard or stem, there may be seal wear. (See Figure 6)
• Solution: Replace the nozzle.

Figure 8
THE NOZZLE SHUTS OFF EARLY (PREMATURE SHUT OFF)
What to check?
√ Check the flow. The flow may be faster than the fill pipe allows. (See Figure 7)
• Solution: Reduce the flow rate by using a lower clip position.
√ Make sure the nozzle is properly inserted in the fill pipe. (See Figure 8)
• Solution: Adjust the nozzle as needed to improve flow.
Note: To verify if it is a vehicle fill pipe situation, check nozzle in an approved test container.
If nozzle functions properly in the approved test container, fill pipe may be cause of premature shut off.
√ Check for debris or foreign material in the venturi port.
• Solution: Remove Debris.
√ Make sure spout is not bent or damaged. (See Figure 9)
• Solution: Replace spout.
√ Check the angle of the spout in the fill pipe. Outlet end of the spout must be below horizontal
or the nozzle will shut off.
• Solution: Reposition nozzle in the fill pipe. (See Figure 10)
NOZZLE HARD TO OPEN
√ Check the hose point static pressure. Maximum static pressure is 50 psi
• Solution: Verify system is relieving pressure.

FILTERS
Dirt and debris in the filter can restrict flow. Check dispenser filters. Replace as required.
(See Figure 11)
HOSES
Inspect your hoses regularly. Restrictions in the line will restrict flow rate. (See Figure 12)
