Answer: It will vary depending on your building
and water department requirements. Many times the water department (at your
cost) will tap into the existing main and run the new fire supply line to
your property line. If that occurs, it is your responsibility to hire a
licensed contractor to continue the fire line into the building. Many
jurisdictions allow a licensed contractor to do all of it. If you hire a
contractor to install your underground fire line be certain that they are
either a licensed fire sprinkler contractor with a N.I.C.E.T Level III stamp
or a license utility contractor with a Washington State Level “U” stamp.
Typically, contractors that go to the extent to obtain these qualifications
are competent in their work and will provide you with a quality job.
