How to Troubleshoot a Pulsating Sprinkler

Turn off the water supply valve. Tag or mark the valve to alert others of the work being done.

Inspect the pulsating sprinkler nozzle for cracks or blockages that may cause reductions in water pressure. Dirt or other forms of debris create problems that affect the performance of the sprinkler.

Check the sprinkler head for freedom of movement from each end of its adjustable arc settings. Some resistance as the head turns indicates that the

internal coil spring which returns the head to its starting position is operating properly.

Check the water pressure at the outdoor bib that supplies water to the pulsating sprinkler with a water pressure gauge. Ensure that all other household faucets, dishwashers and washing machines are off.

Disconnect the hose coupling from the bib. If the coupling is tight, use lock-jaw pliers to turn it counterclockwise. Attach the water pressure gauge coupling to the bib. Tighten it clockwise by hand.

Turn the water on at the bib and check the pressure. For proper performance, the pulsating sprinkler must be supplied with a water pressure level between 30 and 60 lbs. per square inch (psi).

Turn the bib valve off and disconnect the pressure gauge. Connect the hose coupler to the bib and tighten it clockwise by hand.

Disconnect the hose from the pulsating sprinkler and attach the water pressure gauge to the end of the hose. Gauges usually provide the adapter couplings needed for connecting the gauge to the male end of the hose.

Turn the bib valve on to ensure that all other water sources are off as described in step 4. Check the pressure to verify the integrity of the water hose.
