5.) Prior to inserting the flush valve tailpiece (B) into stop
valve (A), be certain that the O-ring seal (C) is located in
O-ring seal groove at the end of the tailpiece and that the
locking nut (D) and locking snap ring (E) are located as
shown. Care should be taken not to damage the O-ring
when inserting the tailpiece into the stop valve. If
lubrication is needed, wetting the O-ring with water will
be sufficient.

3.) When all stops are connected to the water supply and water pressure is available, it is recommended that the supply piping
be flushed to remove dirt, metal chips, etc., from system.
A. Before the valve is installed, open each stop fully for a brief time and catch the water in a two gallon or larger bucket (Figure
3). For multiple installations, start with the stop valve closest to the water supply and work toward the most remote valve.
B. Due to the small passages and orifices, it is not possible to flush the piping through the low volume valve.
C. Once the lines are flushed, the valve can be installed.

4.) Flushometer Installation
A. Drill 1-3/4” diameter hole per Figure 4a.
B.Install the threaded bushing to the rear of the valve. Slip the cover tube and escutcheon onto the bushing (these parts are the
same as used for the stop) see Figure 4b.
