Hazardous Pressure. To be sure air
valve and core cannot blow out of tank, release all
air pressure from tank before removing valve core
or valve.

3. Depress valve core to release ALL air pressure
in tank. When air stops coming out of valve,

7. Push water cell into tank far enough so that you
can get into tank with a dowel rod.
8. Soap the outside of the new valve and mount it
on the end of a piece of 1/4" or 5/16" (5-8 mm)
dowel rod. Push the valve up past the water cell
into its mounting hole in the top of the tank.
Push it through as far as it will conveniently go;
leave the valve cap on to protect the threads on
the valve.
9. Rap the end of the dowel sharply with a ham-
mer to drive the valve into position. Be sure
the shoulder on the valve seats against the tank
head (the ridge around the valve body should
be all the way through the hole in the tank head
– see Figure 6).
