Troubleshooting a Hardie Sprinkler

Locate the main water line and the irrigation line valves if the sprinklers fail to pop up. The master valves could be halfway closed. Grasp the valve knobs or levers of the valves and twist them counterclockwise completely to confirm that both are opened all the way.

Raise the Hardie sprinkler body up, so that the nozzle opening is visible, if water gushes from the sprinkler head. The sprinkler nozzle might be missing or the entire head might be damaged or missing. Use the supplied Hardie adjustment tool to loosen the nozzle chamber, insert a new nozzle and tighten the radius screw to lock the nozzle in place. Replace the sprinkler body if the entire head is missing.

Unscrew the sprinkler head from the top of the sprinkler if water fails to spray from one sprinkler while it sprays fine from others in the same zone. The internal filter might be clogged. Remove the screen from inside the sprinkler and clean it with running water and your fingers. Do not apply oil or harsh chemicals to the screen, as this causes debris buildup. Reinsert the screen and screw the sprinkler head back onto the housing.

Replace the entire sprinkler if the sprinkler remains sticking up after deactivation due to a damaged riser seal or retraction spring. Dig up the sprinkler housing and unscrew it from the swing pipe assembly. Wrap the threads of a new sprinkler base in the direction of the threads with resin tape and screw the housing tightly into the swing pipe assembly. Bury the sprinkler once more in dirt. Confirm that the spray head is level to the ground.

Add another valve to the valve manifold if one valve station doesn't supply enough water pressure to its zone for all of the sprinklers to pop up and water the lawn. Cut the capped pipe extending from the last valve in the valve manifold just before the cap with a pair of pipe cutters. Wrap the threads of a fitting in the direction of the threads and screw the fitting into the inlet of the add-on valve.

Prime a T fitting, the ends a of 3-inch piece of pipe, the previously capped cut pipe and the inlet fitting. Glue the T fitting, the 3-inch pipe, the cut pipe and the inlet fitting together. Screw a fitting into the new valve outlet and split up the sprinklers within the problem zone to make an additional zone. Prime and glue the extra zone pipe line to the new valve outlet.
