It is very important that the arm only be used with our infinity hose. Our arms are not designed to hold the weight of the standard hose and it will cause drifting. Make sure that the hose sits in the clips with the open part of the clip facing up. When moving the arm grab the valve and the clip to position. It is also important to make sure that the arm has not become twisted. A tip to help know if this has happened is to check the writing on the arm and make sure it is in line with the arm, not twisted around.
