Great question! Yes, the J-PRO chlorine pump is designed to run automatically — it only injects chlorine when water is actually flowing, so it's fully on-demand.
There are three ways to set this up:
1. Wire to the Pressure Switch The most common method for well water systems. You install a dedicated outlet that is wired directly into your well pump's pressure switch. When your well pump kicks on (because water is being used), the chlorine pump powers on automatically at the same time. No water flowing = pump off.
2. Use a Flow Switch A flow switch is installed in your water line and connected to the pump. When water flows through the pipe, the switch triggers the chlorine pump to turn on. This is a great option if you want to avoid any electrical wiring to the pressure switch — we sell a pre-wired flow switch that makes this very simple.
3. Proportional Feed with a Flow Meter (J-PRO-22 Proportional model) This is the most accurate method. A flow meter is installed in the water line and sends a pulse signal to the pump for every gallon of water that passes through. The pump then injects a precise, proportional amount of chlorine based on actual water usage — more flow, more chlorine; less flow, less chlorine. This ensures a consistent chlorine residual regardless of how fast or slow water is being used.
All three methods ensure the pump only runs when there's demand, which protects your water supply and extends the life of the pump. Let us know if you have any questions about which option is best for your setup!
