Cleaning or Replacing Injectors
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. This assembly is
easy to clean.
1. Shut off the water supply to your softener and reduce the pressure by opening a cold soft
water faucet.
2. Using a screwdriver, remove the four screws holding the injector cover to the control
valve body.
3. Carefully remove the assembly and disassemble as shown in above figure.
4. The injector orifice is removed from the valve body by carefully turning it out with a large
screwdriver. Remove the injector throat the same way.
5. Carefully flush all parts including the screen. Use a mild acid such as vinegar or Pro-Rust
Out to clean the small holes in the orifice and throat.
6. Reassemble using the reverse procedure.
TIP: There are marks on the in-
jector holder that must be lined
up to the marks on the valve to
fully insert the holder into the
hole in the valve body
TIP: Place the o-rings
A25 and A26 onto the
valve before installing
A33.
