  • Dry Pellet In-Line Chlorinator Model 400 is designed for well water applications, not for pools like other pellet feeders you see online.
  • Designed for installation after a pressure tank.
  • If you are installing it on a continuous pressure line and have no pressure tank, add the Optional Feed Rate Valve.
  • For best results and consistent chlorine dosing we recommend a contact tank be installed after the Chlorinator to give some time after the chlorine has been injected
  • After contact tank to remove chlorine residual if desired install a low cost whole house carbon backwash filter for clean water throughout the house!
  • If being used for residential applications, a whole-house carbon filter is recommended after the contact tank.
  • The Model 400 dry chlorine pellet feeder is designed to operate with a standard well pump and pressure tank, up to 80 PSI.
  • If you have a variable speed well pump that delivers constant pressure we recommend a proportionally fed JPRO-22 chlorinator using liquid bleach
  • No messy chemicals; no moving parts; no electricity required.
  • Corrosion-proof construction.
  • PVC Construction from all NSF-certified materials. PVC used in the Model 400 is NSF certified for drinking water.
  • Adjustable metering of chemicals. Fast and easy refilling.
  • Never needs priming.
  • Holds about 4 lbs of 3/8" pellets in one filling.
  • One filling with pellets will typically treat 15,000 to 20,000 gallons of water before requiring refilling.
  • For best results use the Sentry 3/8" 1 gram pellets.
  • When adjusted to the #1 hole setting, the unit should dispense approximately 2.0 ppm of chlorine and the system should process approximately 15,000 to 20,000 gallons of water before needing to be refilled.
  • Easy to install.
  • Note: For gravity or non-pressure tank installations, the optional Feed Rate Valve must be ordered separately.  
  • NOT FOR USE on constant pressure variable speed well pump systems.  Works great for standard pressure tank well pump systems but do not recommend for use for constant pressure systems where there is no pressure tank.
  • For best results, use a contact tank and carbon filter after the Model 400.
  • Includes two 1-1/2" PVC slip unions plus two 3/4" NPT (threaded) unions.
  • If you have 1" or 1-1/4" pipe, you can purchase bushing reducers to go from 1-1/2" to your pipe size at most hardware stores
  • Designed for flow rates up to 15 gallons per minute but much higher flow rates possible.

  • NOTE:While this is feeder is made from FDA Approved Materials, it is not NSF Certified. If your application is a commercial application requiring NSF certification please contact us for a liquid bleach feeder pump.
Install with 3 valve bypass so you can partially bypass Model 400 if chlorine levels are higher than you need.   

In some cases the Model 400 will dispense 5 to 10 PPM of chlorine even at the lowest setting.  If your water does not need this much you can partially open the bypass valve to lower chlorine levels.

For best results we recommend a contact retention tank and carbon filter after the Model 400.

The middle valve is normally closed, however it can be partially opened to lower chlorine levels.
