Last year I hired someone to blow out the sprinklers but I took pictures and had him show me what to do so I could do it myself this year.
Just tried, did everything he showed me but got nothing coming out of the sprinklers when I had the compressor hooked up.
I'm thinking that maybe it's because I have a very small "Pancake" type compressor, does that sound right? So what is the minimum size of the compressor/tank that people are using to blow out sprinklers? I don't really want to get another compressor as the pancake compressor seems to work fine for everything else I need it for.
