OK to cap off a inground sprinkler head???
Due to changes in our garden, I have a couple of sprinkler heads that are unneeded. Can I just take out the sprinker head and just cap it off? What I wonder about is that water would not be expelled from that line when the system is blown out at the end of the season and that the water would freeze and break the line. Or should I extend the line up, cap it and remove the cap when it is time to blow out the lines?
Similarly, I have 'lost' one of my sprinkler heads - it did not come out this spring and I don't know close enough where it is. No wet ground to give a clue either. Will abandoning this head give the same problem as above?
