Top 3 Ways to Automatically Turn On and Off a Home Well Water Chlorinator

You might be asking “What is the best way to install a home well water chlorinator so it turns on and off automatically?”

This is a common question for everyone on well water wanting to use a home well water chlorinator.

Metering pumps are used to inject a small amount of liquid chlorine bleach  into the water, usually in conjunction with a contact tank.  The pumps draw chlorine bleach from a solution tank and pump it into a pipe under pressure. 

Chlorine Bleach Solves a Lot of Problems for a Low Cost

Water used for drinking and cooking should be free of odor, slime producing bacteria,  and pathogenic (disease causing) microorganisms that cause such illnesses as typhoid fever, dysentery, cholera, and gastroenteritis.   

Although several methods eliminate microorganisms and odors in water, chlorination is the most commonly used. Chlorination is effective against many pathogenic and non-pathogenic bacteria, but at normal dosage rates it does not kill all viruses, cysts, or worms.

Often combined with filtration to remove the chlorine from the water used inside the home,  chlorination is an excellent and cost-effective way to disinfect drinking water supplies, eliminate odors, and oxidize iron, and other metals.





 Top 3 Ways to Turn On and Off A Home Well Water Chlorinator

Chlorinator metering pumps need to be installed so they turn on and off automatically. There are three methods commonly used: 

  1. Wire to turn on and of with the well pump pressure switch
  2. Use a flow switch
  3. Use a proportional-feed flow meter


OPTION 1:  

By Well Pressure Switch: In this type of installation, the metering pump is plugged into a dedicated electrical outlet that is wired in to the pressure switch.  When the pressure switch points close, the  chlorine solution pump is turned on.  This a reliable and  low cost option.  An electrician may be needed to comply with local codes and/or if you are unfamiliar with basic wiring.   



OPTION 2: PRE-WIRED FLOW SWITCH

An easy alternative to installing  a dedicated outlet and wiring  to the pressure switch is to use a pre-wired flow switch.  The flow switch cord is plugged into any 120V wall outlet, and the chlorinator pump is plugged into the outlet that is built in to the flow switch.  
Whenever there is flow, the chlorinator pump is energized and starts to pump.  Easy to wire, just plug in, turn on.   Available in 110v or 220v.


OPTION 3: PROPORTIONAL FEED FLOW METER 
In some applications the chlorine injection point must be after the pressure tank, such as when the pressure tank and well are away from the house and it is impractical to have the chlorine being injected before the pressure tank. 
In this case, a Proportional-Feed system can be used.  Based on how fast the water is flowing, more or less chlorine is pumped into the water to maintain a precise residual.  
Like the flow switch, it is  easy to install, and allows installation of your chlorination system anywhere after the well pressure tank.    
Whenever there is flow, the chlorinator pump is energized and starts to pump.  Easy to wire, just plug in, turn on.   Available in 110v or 220v.
