Assembly Instructions
1. Familiarize yourself with all of the automatic float valve components.
a. Open the loose parts bag and inventory the contents.
b. The plastic orifice insert and hose washer is already assembled in the
valve housing. Make sure the orifice insert and washer are firmly
seated against the valve housing.
c. The rubber valve seat is already
pinned to the float. Make sure the
seat and pin are firmly seated against
the float.
2. Position the float assembly inside
the valve housing and slide the large
2-1/4" cotter pin through the housing
and the float assembly (see Figure 1).
Spread the ends of the large cotter
pin open slightly with pliers. When
properly installed, the float assembly
should pivot freely on the cotter pin

tory the contents.
b. The plastic orifice insert and hose
washer is already assembled in the
anti-siphon valve housing. Make
sure the orifice insert and washer are
firmly seated against the anti-siphon
valve housing.
2. Position the anti-siphon valve stem as-
sembly in the slot of the float and slide
the 1-1/8" cotter pin (smallest of the
two cotter pins) through the float and
the valve stem assembly (see Figure
2) then spread the end of the cotter pin
open slightly. When properly installed,
the valve stem assembly should pivot
freely on the cotter pin inside the float.
3. Thread the anti-siphon valve housing all
the way into the valve housing.
4. Position float assembly inside valve
housing and slide the large 2-1/4"
cotter pin through the housing and the
