7. Push bladder 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" dowel
rod. Push the valve up past the bladder 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).
