Cause:

1. Sprinkler not connected to any piping or piping goes straight through head 2. Sprinkler (and piping) is almost but not quite not connected into the main piping network
Solution:

1. Sprinkler will be marked in red - connect sprinkler to piping or delete sprinkler. Sprinkler may not be visible on screen - use zoom extents command. 2. Lines may be drawn, but do not get broken properly at tees, look for two (2) tees inserted almost on top of each other where there should be only one (1) tee.
