TROUBLESHOOTING AND MAINTENANCE
Troubleshooting
Insufficient Bubbler Flow:
Check that the shut-off valve is wide open. Verify minimum 20 PSI supply pressure. Clean inlet strainer screen located in the valve
body. Clean rubber orifice in flow control located below frost line in bushing between barb fitting and valve.
No Flow:
Check for leaks in the air tubing going from the push button to the valve. Make sure the air tubing compression nut is hand tight. Disconnect air tube from
push button. Place finger over air outlet. Push button to test diaphragm. Tighten diaphragm cap screws. Replace diaphragm if necessary.
Continued Insufficient or Varied Height of Bubbler Flow:
•
Check for kinks in the tubing.
•
Remove the valve assembly from the PVC column by carefully pulling up on the strap and connecting tubing at the same time. Check stream height from the
bubbler. Stream height is factory set at 35 PSI. If supply pressure varies greatly from this, adjust the screw on the regulator (Item 13, Fig. 4, Page 6). Clockwise
adjustment will raise stream and counter-clockwise adjustment will lower stream. For best adjustment stream height should be approximately. 1-1/2" (38mm) above
the bubbler guard. Replace the valve into the PVC column. Make sure the supply hose coils into the bottom of the PVC column without any kinks and double check
that the valve is positioned fully at the bottom of the PVC column.
Continuous Bubbler Flow:
Insure that push button is not obstructed and springs back to normal position. Remove four screws which secure plastic diaphragm block
to valve body. Pull plastic and rubber diaphragm assembly out of valve body. Locate tiny hole in rubber diaphragm just under lip of plastic part. Clean debris from this
hole. Inspect valve seat for grooves. If valve seat was OK and diaphragm hole was free from debris, inspect rubber button located at center of floating steel disc in valve
diaphragm block assembly. If button is worn, turn disc over or replace it. If diaphragm and seats are in good condition, stretch spring slightly. Spring is located behind
floating stainless steel plate. Insure that air bleed port on valve plastic block assembly is not plugged.
