This invention relates to diverter spouts, and it more
speci?cally resides in a spout having an outlet chamber
connected to an inlet through a valve port that may be 10

so as to be completely serviceable from the exterior with
out necessitating removal of the spout from its connecting
plumbing. This is accomplished by the provision of a
removable plug which forms a part of ‘the lower outer
wall of ‘the diverter and which is disposed below the valve
stem. Removal of the plug gives access to the valve,
which then may be removed from its stem, and the stem
in turn is then removable from the spout body. Thus,
all parts are accessible after removal of the plug for
servicing or replacement.
It is, therefore, an object of this invention to provide
a diventer spout which is simple in construction and oper
