I have a sprinkler zone that has low pressure. I've bypassed the valve and observed the same problem, so it's probably not the valve.
The weird thing is, if I manually pull the plunger fully up on the first sprinkler head in the line, this first head then regains the normal water spray pressure. Not only that, but then the rest of the sprinklers down the line all get improved spray pressure as well.
But if I let go of this plunger, it falls down to about half height, and every sprinkler in the line all start to lose pressure again.
I'm at a loss as what to do next. Is this a leak? a clog? I don't see a puddle anywhere, so to find a leak might mean digging up the entire line.
Thanks in advance!
