I have one ceiling fire sprinkler that is in my basement that is not positioned low enough for when you drywall the ceiling. I have looked at the plumbing and the fire sprinkler system in not tied directly into the city main water. So I can turn the water off myself. I can then drain the sprinkler line from the test spinket. The pressure drops to 0. Can I then unscrew the sprinkler, cut the pipe, lenghten the pipe and then screw the sprinkler back on myself. Look as though sprinkler head just screws into end of pipe and teflon tape on the screws.

Can I do this myself? Suggestions.

Thanks

Yes, this is generally a simple plumbing procedure. My only concern is your mention of cutting the pipe. Of course if it's copper, then cutting it is fine - then solder a longer piece in there... but if it's galvanized, then you'll want to not cut, but go back to a threaded elbow or union and use a longer piece there. Does that make sense?

If you can include a photo of it, that would help.

Rick,

The pipe is 3/4 copper. So I don't have to worry about the pressure issue if I can shut the water off and drain the release value.

Right. Adding a longer piece of copper to that part will be as uncomplicated as doing so anywhere else in your home.

Awesome. Do you think I will have any issues unscrewing the head and putting it back on. Have you seen it done before?
