Troubleshooting
Insuffi cient 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
orifi ce in fl ow control located below frost line in bushing between barb fi tting 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 fi nger over air outlet. Push button to test diaphragm. Tighten diaphragm cap screws.
Replace diaphragm if necessary.
Continued Insuffi cient or Varied Height of Bubbler Flow:
•
Replace fl ow control.
•
Check for kinks in the tubing.
•
Remove the cleanout plug from the PVC column. Remove the valve assembly from the
PVC column by carefully pulling up on the strap and connecting tubing at the same time.
Pressure test the valve assembly for leaks. 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. 5, Page 10). Clockwise adjustment will raise stream and
counter-clockwise adjustment will lower stream. For best adjustment stream height should
be approx. 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. Cap 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 fl oating 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 fl oating stainless steel plate. Insure that air bleed
port on valve plastic block assembly is not plugged.
