In a previous post the advice was given to systematically "cap off" pop-up head to locate a break in the line. Can this be done with the rain bird 2 1/2 pop-ups. I inherited a system when I bought my current house and started it up for the season (probably too early). There was a head that was leaking where it connects to a 1/2 close size riser that connects to a tee in the main line. I replaced the whole sprinkler after finding that they are cheap to buy. Everything was fine and then another head leaked and now i have another. Now when the system turns on all 5 heads just bubble until I manually pull one or two of them up and then everything is great. Please help.
You can cap off the heads.....
There should be a screw on top of the nozzle on all the heads, turn them until there is no water shooting out anymore. There might be a little trickling out, but that is ok.
