CLEAN INJECTOR ASSEMBLY - FOR MODELS BEFORE JUNE, 2022
Sediment, salt, and silt will restrict or clog the injector. A clean water supply and pure salt will prevent this from happening. The injector assembly is
located on the right side of the control valve when facing your softener.
The assembly is easy to clean, start by:
1.
Shut the water supply to your softener OFF.
2.
Reduce the pressure by opening a cold-treated tap.
3.
Using a screwdriver, remove the four (4) screws holding the injector cover to the control valve body.
4.
Carefully, remove the cover, and disassemble as shown below.
5.
The injector orifice is removed from the valve body by carefully turning it out with a screwdriver.
6.
Remove the injector throat the same way.
7.
Carefully flush all parts including the screen.
8.
Use a mild acid such as vinegar or Pro Rust Out to clean the small holes in the orifice and throat.
