ABSTRACT:
A sprinkler flow control fixture for insertion between a water main and a sprinkler head contains a solid wall separating the inlet side from the outlet side with a passage therethrough calibrated to permit a flow rate of about 130% the normal flow of the sprinkler head so that removal of the head will not result in excessive water loss and drop in water main pressure.
