Q:I have played with the pins underneath, shaken it thinking it’s stuck, but to no avail. It just gets to the end of a spray cycle and sticks without rotating back. If this was once i would think it’s a faulty sprinkler but happening three times?

        A:  Yes and the rotation is adjustable to the direction you adjust it to. It's adjusted with your fingers. No tools required.

        by|Jul 16, 2021

          A:  The unit should be rotating as long as you have a minimum of 20 psi. If this unit is not working please contact us and we will be glad to take care of this matter for you. 1-877-283-0697

            A:  It has a little clip under the the spigot that you can adjust for full rotation or partial. It works really well. It's the best sprinkler I've used.

            A:  More than adequate. I run mine at 2 hr. increments to avoid useless runoff.

              A:  Please contact Melnor Inc. customer service 1-877-283-0697.

                A:  I don't know any numbers. I DO know that it works OK with a pocket type hose but very well with a normal hose of 50. My only gripe with it was that water came out in too narrow a stream because there wasn't enough length on the diverter screw. So I twisted a small wall anchor to the screw and now it works like I want it to. (I wanted a larger coverage area). There's never an issue with amount of water being sent out, even with 100' of standard hose.

                Q:How is oscillating set?

                Answer This Question

                A:  The sprinkler has two rings at the bottom that you move with your finger to wherever you want the sprinkler to stop and reverse directions. See the yellow arrow in the attached photo. In this photo the rings are both together which will give you almost 360 degrees of coverage. You can move one or both of the rings until you get your desired sprinkler reversing point. When the metal tab where the red arrow is pointing touches a ring the sprinkler then reverses direction.

                by|Jul 17, 2021

                  A:  Use the metal adjusters under the sprinkler head. Adjust any way you want. You can do it with a fingertip and don't really have to worry about a "right" way. Just get the water in the pattern you want.

                  by|May 5, 2023

                    A:  There are 2 adjustable 'stops' at the bottom of the sprinkler that you turn to set the oscillating angle.

                      We have a well, and not great water pressure. This sprinkler needs better water pressure to turn properly.

                      This sprinkler is extremely well built. It has excellent coverage and an adjustable spray pattern. I use a shallow irrigation well to water my lawn and garden. The well produces sand and sediment. This pulsating sprinkler does not clog and consistently delivers full water pressure. I am so pleased with the performance of this sprinkler that I am going to purchase another.

                      The main return spring broke and rendered it useless after 3 weeks.

                      Melnor has been an excellent brand in the past and I had high hopes I finally found a decent pulsating sprinkler. These two sprinklers worked for 2 days and then they would not rotate. They will be returned on 8/31/23.
