So my genius husband never blew out our sprinkler system. One cold December day the back flow valve broke & we had a slight geyser in our front yard. So I have spent the entire spring & summer without a sprinkler system.
Since it takes about 4 hours to water my entire front & back yard, it didn't happen very often. So now I have a very lovely dead grass/dandelion yard. It really a joy to look at :)
We were finally able to bring out the sprinkler guy. After only $161, we now have a sprinkler that works again!!!
AND he says if we start watering it daily then it should actually get green again THIS year. I don't have to wait until next spring to have a green yard again. Yippee!!!
