I am having a heck of a time with clogged sprinklers. I am on a well. My three arm twirlers stopped twirling and I found one arm FULL of larva type worms. My front sprayer worked fine last week and this week I found it clogged with tiny green leaves. It took me 45 minutes to get water to flow once again. What gives and how does one keep them from clogging up? Lime deposits would make more sense to me but that is so not the problem. I have my sprinklers attached to smaller hose sections and sitting in the gardens 24/7. This way I just attach the yard hose to each area as I go and I do not have to get muddy shoes or risk trampling plants. I place the sprinklers each spring before the perennials are up. How in the world are they getting leaves and worms in them?
