C-Series Injector, Black, 13" DF/16" UF

C-Series Injector, Black is the draw injector that pulls brine or chemical into a Nelsen C-Series valve during regeneration, color-coded black for its flow rating.

• Black-coded injector for C-Series control valves
• Sized for 13" downflow (DF) tanks and 16" upflow (UF) tanks
• Creates the suction that draws brine from the tank into the media bed
• Injector rating is matched to tank diameter and flow direction for correct draw
• Very light component, only a few grams in weight
• Genuine Nelsen part for C-Series valves

Replace the injector when a C-Series system stops drawing brine, regenerates weakly, or leaves media under-regenerated, which often traces to a clogged or worn injector. Color coding matters: the black injector is matched to the 13" downflow / 16" upflow range, so confirm your tank size and flow configuration before fitting it. Keep the injector screen clean to maintain reliable brine draw.

C-Series Black Injector

This is a replacement injector for C-Series control valves, identified by its black color coding and sized for the tank diameters noted in the title. The injector is a small but essential part that creates the suction needed to draw brine from the salt tank into the media during the regeneration cycle of a water softener. Its color code corresponds to a specific flow characteristic matched to the valve and tank it serves.

Signs You May Need a New Injector

Because the injector handles the brine draw, problems here often show up as water that is no longer being softened properly. If you notice the salt level in your brine tank barely changing, water that feels hard again after regeneration, or a system that seems to cycle without pulling brine, a clogged or worn injector is a frequent culprit. The small internal passages can become fouled with sediment or mineral scale over time, restricting the suction the system depends on.

Service and Fitment

Injectors are serviceable parts and are usually cleaned or replaced during routine maintenance. Using the correct color-coded injector for your valve and tank size matters, because an injector that does not match can throw off the brine draw and hurt regeneration performance. It is important to match the part to your specific C-Series valve configuration.
