Buying Guide: How to Choose a Chlorinator for Your Well Pump
Selecting the right chlorinator involves more than just picking the cheapest model. You need to consider your well’s flow rate, pressure, available power, and the type of chlorine you plan to use. Below are the key factors to evaluate.
Flow Rate and Output Capacity
The chlorinator’s output must match your water usage. A small household with moderate demand may do fine with 30 gallons per day (GPD), while a large home with irrigation might need 60 GPD or more. Precision Controls offers both 31.6 GPD and 63.4 GPD models to cover these scenarios. For high-demand applications, the Precision Controls Chemical Metering Pump (63.4 GPD) is an excellent choice.
If your well pump delivers high pressure (above 80 PSI), ensure the chlorinator can handle it. The Precision Controls PF30 series works up to 150 PSI, making it suitable for pressurized lines. For deeper wells, see our Deep Well guide for compatible pumps.
Power Source and Voltage
Chlorinators come in 115V and 230V versions. Most homes have 115V outlets, but some pump houses are wired for 230V. The Precision Controls PF30 is available in both voltages, while the Pulsafeeder X030 runs on standard 115V. If you are installing in a remote location, consider a peristaltic pump like the Stenner 85MJH2A2S Peristaltic Adjustable-Head, which offers consistent dosing at 100 PSI.
Always verify your power supply before purchasing. Universal voltage motors (100-240V) provide flexibility for future changes. For a complete well pump setup, check our Well Pump Kit page.
Chemical Compatibility and Maintenance
Not all chlorinators handle the same chemicals. Sodium hypochlorite (liquid chlorine) is corrosive, so the pump’s liquid end must be made of PVC, polypropylene, or other resistant materials. The Pulsafeeder Chem-Tech series uses a PVC head with CSPE seals for durability. For dry chlorine pellets, the GBBC Chlorine Well/Pool SANITIZER PELLETS (2X) are designed for use with LAND-O-MATIC or similar pellet feeders.
Peristaltic pumps like the Stenner are self-priming and handle viscous chemicals well, but require periodic tube replacement. Diaphragm pumps, such as the Precision Controls, have fewer wear parts and are easier to maintain. For submersible well pump options, browse our Submersible category.
Installation and Kit Contents
A complete installation kit saves time and ensures proper setup. Precision Controls includes an injection check valve, suction line, foot weight, and tubing with their pumps. The Swimline Hydrotools 87501 is a simple inline feeder that connects directly to your pool or well plumbing with no wiring required. For a budget-friendly solution, the SWIMLINE HYDROTOOLS 87501 Economy In-Line feeder works well for pools and low-demand well systems.
If you are handy with tools, most chlorinators can be installed in a few hours. However, for complex setups involving pressure tanks or multiple injection points, professional installation is recommended. Learn more about system components in our Chlorine Injection Pumps category.
Final Thoughts
After reviewing the top chlorinators for well pumps, our recommendation depends on your specific needs. For most residential well owners, the Precision Controls Chemical Metering Pump (115V, 31.6 GPD) offers the best balance of performance, ease of installation, and value. If you need higher output for irrigation or a larger home, the Precision Controls Chemical Metering Pump (63.4 GPD) delivers double the capacity without sacrificing precision. Both models come as complete kits, making setup straightforward. For those who prefer a peristaltic design with proven reliability, the Stenner 85MJH2A2S remains a top contender. Whichever chlorinator you choose, you will enjoy peace of mind knowing your well water is consistently treated and safe.
Frequently Asked Questions
How does a chlorinator for a well pump work?
A chlorinator injects a precise amount of chlorine (usually sodium hypochlorite) into the water line after the pressure tank. The chlorine mixes with the water as it flows to your taps, killing bacteria and oxidizing iron and sulfur. Most systems use a metering pump that adjusts the dose based on flow rate or time.
What size chlorinator do I need for my well?
The size depends on your daily water usage and the concentration of contaminants. A typical 3-bedroom home uses 200-400 gallons per day, so a pump rated for 30-60 GPD of chlorine solution is sufficient. For heavy iron or sulfur, you may need a higher output. Always consult a water test before choosing a chlorinator.
Can I use a pool chlorinator for my well water?
Pool inline feeders like the Swimline Hydrotools 87501 can be adapted for well water, but they are not designed for high-pressure well systems. They work best on low-pressure lines or gravity-fed setups. For most wells, a dedicated chemical injection pump is more reliable and precise. Read our Chlorine Injection Pumps guide for compatible options.
How often should I replace the tubing on a peristaltic chlorinator?
Peristaltic pump tubing should be replaced every 6 to 12 months, depending on usage and chemical concentration. The Stenner 85MJH2A2S uses Santoprene tubing that resists wear, but regular inspection is key. A worn tube can cause inconsistent dosing and leaks.
