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

Matt

If you do this yourself, you just violated any warranty or guarantee the sprinkler company has issued for this system. The fire sprinkler IS tied into the city water main. How else would it work?
