The entire plumbing and drainage system within
the building must be tested by the plumber in the presence of an inspector
of the Building Department under a water test. All pipes must remain
uncovered in every part until they have successfully passed the test.
The plumber must securely close all openings, as directed by the inspector.
The use of wooden plugs for this purpose is prohibited.
The water test will be applied by closing the
lower end of the main house drain and filling the pipes to the highest
opening above the roof with water. The water test shall include at
one time the house drain and branches, all vertical and horizontal
soil, waste and vent and leader lines and all branches therefrom to
a point above the surface of the finished floor and beyond the face
of walls and partitions. If the drain or any part of the system is
to be tested separately, there must be a head of water at least six
feet above all parts of the work so tested, and special provision
must be made for including all joints and connections in at least
one test.
After the completion of the plumbing work in
any new or altered building over six stories high and before the building
is occupied, a final smoke test must be applied in the presence of
a Plumbing Inspector.
The material and labor for the test must be
furnished by the plumber.
