1. First be sure line on which hydrant
is to be installed has been throughly flushed to
wash out foreign particles,
rocks and sand. |
| 2. Be sure the hydrant is installed
with provision for drainage below frost line. |
| |
a. If hydrant is installed in a pit,
the pit must have an open bottom or some form
of drainage. |
| |
b. If hydrant is buried in the ground, a few tile
can be laid in gravel or coarse
material to form a field system for the
drain. |
| |
c. If hydrant is buried in ground and no tile are
used, be sure to put a quantity of
gravel, crushed rock or some coarse
material around the drain of the hydrant.
This will permit faster and
better drainage. |
3. If hydrant is buried in
the ground it is a good idea to put a brick or
large stone under the
hydrant, because when the hydrant drains and the subsoil
becomes wet,
it will allow the hydrant to settle and thus put a strain on the pipe
to
which it is connected. A brick or stone would carry this weight. |
4. To connect the hydrant to the line,
just turn it onto the male thread on the
bottom of the valve body, for which it is intended. |
| |
a. When the hydrant is tightened, be careful
that it is not tightened so
tightly that the hydrant head or valve body
will be screwed further onto the pipe
and thus
change the adjustment of the hydrant. If this should happen, adjustment
on the hydrant stem rod can be made by turning the two nuts.
Simply
remove the bolt that holds the lever and pull it out of position and
slip the
draw straps off the lever and make any adjustment neccessary. |
| |
b. The correct adjustment of this hydrant can be
checked by raising the lever.
Water
should not run through the hydrant until the lever passes the half way
point
or horizontal position. When water is flowing through the hydrant it
should shut
off when lever comes down to the horizontal point. |
|
1. In maintenance, nothing is needed
- but, a few drops of oil occasionally on the cam
of the lever will prolong
its life. |
2. To replace any valve or plunger parts,
- Simply mark
threads
on pipe and unscrew head from stand pipe and pull up stem and valve
plunger. |
