2.10 Injector Water Supply
The injector requires a supply of reasonably clean water. Equip the water
supply up to and including two-inch sizes with a strainer, as indicated in the
Typical Installation drawing in this section. The pressure and quantity of water
required varies from one installation to another.
2.11 Drain
Two-inch bellofram type injectors used for start-stop operation require a 1/4-
inch ID drain hose to dispose of a short spurt of water when the injector is
operated. Run the drain hose to a suitable floor drain or waste pipe.
For one-inch and 3/4-inch fixed throat injectors, no floor drain is required;
however, a drain is always desirable to facilitate injector service.
2.12 Injector Discharge
For 3/4-inch fixed throat injector, the tailway (beige color) is designed to accept
3/4-inch polyethylene tubing or 3/4-inch threaded pipe connection.
NOTE: For pipe thread connection, do not cut off the serrated section.
For one-inch fixed throat injectors, a rigid PVC pipe or Evoqua Water Technolo-
gies solution hose is required between the injector discharge and the point of
application. The pipe size depends on the size of the throat and tailway used
in the injector, the operating water pressure, and length of the solution line.
Solution hose may be connected directly to the injector tailway. If rigid PVC pipe
is used, a piece of straight pipe at least eight inches long should be coupled to
the end of the injector tailway before any elbows, tees, or Saunders valves are
used. This is to prevent any flow disturbances that could affect the hydraulic
performance of the tailway connections (see Dwg. 25.200.003.010).
For the two-inch variable throat injectors, two-inch polyethylene pipe or two-
inch rigid PVC pipe is normally used. Solution hose may be connected directly
to the injector tailway. If rigid PVC pipe is used, a piece of straight pipe at least
12 inches long should be coupled to the end of the injector tailway before any
elbows, tees, or Saunders valves are used. This is to prevent any flow distur-
bances that could affect the hydraulic performance of the tailway. Discharge
in an upward direction.
