Causes

Solutions
Pressure depth readings are erratic.
Pressure vent tube may be pinched or blocked with
water.
Pressure dryer tube may not be functioning properly.
Black cap may still be on the dryer tube.
Desiccant has absorbed too much moisture and no
longer allows the dryer tube to function properly.
Inspect color of desiccant in dryer tube and replace the
dryer tube if necessary.
Inspect the vent tube along its entire length to ensure
the cable is not pinched and that the cable ties securing
the vent tube are not too tight.
Verify that the black cap has been removed from the
dryer tube.
