Our sprinkler system has many daisy-chained sprinklers -- not the way to
do it, I understand, but that's the way they were.
A week or two ago I managed to chew up a sprinkler with the mower, and
when I unscrewed the damaged sprinkler dirt and stones fell into the
Tee. I cleared away all I could reach, then turned on the water to blow
out the rest. Unfortunately, it seems as though some continued straight
on -- toward the next sprinkler -- instead of blowing out from the one I
was working on. Now there is barely a trickle from that next sprinkler.
What would be the best way to clear the line? It's 3/4-in poly pipe.
I've thought of unscrewing that next sprinkler and trying to push stiff
wire back along the pipe, but is there a better way?
And is there a good way to prevent the problem in future? How does one
stop dirt and stones falling into the open line?
