Replace and old sprinkler head and raise new head.

just an FYI, no need to use Teflon tape on the output side of the values, there is really no need. Now if your working on the input (supply) side of your sprinkler system values, then you will need the Teflon tape. Just a friendly advise and it will save you time and frustration. Its not going to hurt anything if you do add the tape, but there's no need. Keep up the good work
