[Schmitth]

With the dry spell that we recently went through, I was able to assess the areas where the sprinkler system wasn’t reaching.
Zone by zone I removed the heads of all the sprinklers. I noticed that out of the nine sprinklers in that zone at least two were pushing mush less water pressure. I replaced the heads and of course those same two sprinkler heads had little output.
I’d like to get these two heads up to speed with the other sprinkler heads within this same zone.
Can anyone provide me with details to fix this issue.
