6.9.2 Tighten Valve Seat
The pellet feeder ball valve is designed to drop the bio-reporter pellets into a pressurized water line.
As the pellets are fed a small amount of water equivalent to the displacement of the pellet will weep
from the valve through the side drain port. This is normal and no cause for concern. Over time the
seats may wear slightly and a larger amount of water may weep from the valve. This is an indication
that a seat tightening is required.
STEP 1
-
Turn off power to the pellet feeder (switch located below hopper see
Figure PF2).
STEP 2
-
Remove the upper plumbing assembly to access the top of the ball valve. This is
done by removing the upper union fitting and the pipe strap (see Figure PF3).
Note
: Under normal operation, the side drain port should be plumbed to drain, or connected to the
bio-reporter Liquid Overflow Container (
P/N 060-TR5350.88
).
