Tonight while I was adding some chlorine to my spa I had the pumps on low and noticed that one of the neck jets on my week old Sundance Solo was spraying across the spa and the other was just spraying about six inches. I tried the pumps on high, but one just seems to have about a quarter of the pressure of the other one. There is no independent adjustment of the neck jets, so for some reason one blasts while the other doesn't. Does anyone have any ideas on what could be the problem?
