I bought my house last fall and never used the sprinkler system. Actually I've never lived in a house with a sprinkler system (yes I know I'm a heathen.) Here is a picture of the booster pump in the basement. Do I have everything labeled correctly? This is a photo of one of the sprinklers in the back yard. It pops about 1/2" and shoots 2-3 streams of water. All of the sprinklers in the back yard are similar. Anyone have any idea how old this system is? I have PGP's in the front yard and a mix of new sprays and old brass sprays in the back and side yard. Here's a photo of one of the brass sprays. The sprays around the house are on copper risers with brass heads.
