servicing, maintenance and equipment removal without system shutdown.

SECTION 15110
VALVES
1. Locate valves for easy access and provide separate support where necessary.
2. Install valves in horizontal piping with stem at or above center of pipe.
3. Install valves in position to allow full stem movement.
C. For chain-wheel operators, extend chains to 1500 mm (60 in.) above finished floor
elevation.
D. Installation of Check Valves
1. Install for proper direction of flow as follows:
a) Swing Check Valves

1) Horizontal position with hinge pin level.
b) Wafer Check Valves

1) Horizontal or vertical position, between flanges.
c) Lift Check Valve

1) With stem upright and plumb.
E. All valves and appurtenances shall be installed in the locations shown, true to
alignment and rigidly supported. Any damage to the above items shall be repaired to
the satisfaction of the Royal Commission before they are installed.
F. Valves shall be carefully inspected, opened wide and then tightly closed and the
various nuts and bolts shall be tested for tightness. Special care shall be taken to
prevent any foreign matter from becoming lodged in the valve seat. Valves, unless
shown otherwise shall be set with their operator shaft vertically. Any valve that does
not operate correctly shall be removed and replaced.
G. Valve boxes shall be carefully centered over the operating nuts of the valves so as to
permit a valve wrench or key to be fitted easily to the operating nut. Valve boxes shall
be set to conform to the level of the finished surface and held in position by a ring of
concrete placed under the support flange. The valve box shall not transmit surface
loads to the pipe or valve. Care shall be taken to prevent earth and other material
from entering the valve box. Any valve box which is out of alignment or whose top
does not conform to the finished ground surface shall be dug out and reset. Before
final acceptance of the work, all valve boxes shall be adjusted to finish grade. Valve
operating risers shall be installed with any valves required to ensure that the
operating nut is 750 mm (30 in.) or less from the ground surface.
H. After installation, all valves and appurtenances shall be tested at least 1 hour at the
working pressure corresponding to the class of pipe, unless a different test pressure
is specified. If any joint proves to be defective, it shall be repaired to the satisfaction
of the Royal Commission.
I. Install all floor boxes, brackets, extension rods, guides, the various types of operators
and appurtenances as shown on the drawings that are in masonry floors or walls and
install concrete inserts for hangers and supports as soon as forms are erected and
before concrete are poured. Before setting these items, check all plans and figures

thoroughly cleaned. The ends of the pipes and outside of the gaskets shall be
moderately coated with petroleum jelly, cup grease, soft soap or graphite paste and
the gasket shall be slipped over one pipe end. After the other pipe has been brought
to the correct position, the gasket shall be centered properly over the pipe ends with

the already laid pipe end until it is properly centered over the joint. The other pipe
end shall be inserted into the middle ring and brought to proper position in relation to
the pipe already laid. The gaskets and followers shall then be pressed evenly and
firmly into the middle ring flairs. After the bolts have been inserted and all nuts have

uniformly tightened all around the joint, preferably by the use of a torque wrench of
the appropriate size and torque for the bolts.
