My crown head empties into a holding tank. Since we don't use
the chemical tank that used to draw into the bowl as you flushed
can I just cap it off. The book says it flushed better with fluid
being drawn from the little tank......does not seem to be getting
much water at the front of the bowl.
Yes, go ahead and cap it off. You can snip off the clear plastic tube about 2"-3" from where it attaches to the toilet, and stuff a golf tee or large screw into the end of the tubing to seal it off.
