ABSTRACT:
A sprinkler head having a readily accessible top plug which can be removed and replaced by a pressure-reading gauge that is in fluid communication with the head's interior pressure. Each individual sprinkler head includes a manually-adjustable pressure adjusting screw which is accessible at an exposed location for the installed sprinkler head. Pressure adjustment for an individual head, while it is operating in either a manual or an automatic mode, is available. After individual pressure adjustment for a sprinkler head has been performed the gauge is removed and the plug is replaced for normal sprinkler operation.
