I have a line of about 5 heads. The ones farthest away from the valve are working perfectly. The 3 closest to valve only go part way up and if I manually pull them up, they often stay up even after the water is turned off. The farther ones working would tend to argue against pressure issues. Does it seem the best idea to just replace those three or is there some other diagnostic trick I should try first?
