4.3.4 Injection/Check Valve Fitting Installation - The Injection/Check valve
fitting is designed to install directly into either 1/4” or 1/2” female pipe
threads.
Install the Injection/Check valve directly into the tee fitting. Do not install the
fitting into a pipe stud and then into the tee. The solution must inject directly
into the flow stream.
Use PTFE thread sealing tape on the pipe threads. Push the opaque outlet
(discharge) tubing onto the compression barb of the Injection/Check valve
fitting. Use the tube nut to secure the tube. Hand tighten only.
Injection/Check valve fitting fitting will require periodic cleaning, especially
when injecting fluids that calcify such as sodium hypochlorite. These lime
deposits and other build ups can clog the fitting increasing the back pressure
and interfering with the check valve operation. See section 6.0.
