Chemical Feeders, Acid Delivery, and Dosing Hardware
Treat erosion feeders, liquid chlorine pumps, acid tanks, and injection systems as calibrated equipment with chemical-compatibility and storage risks, not as set-and-forget accessories.

Acid and chlorine systems require hard separation
Do not improvise storage, tubing, or injection layouts where incompatible chemicals, fumes, or leaks can interact. Feeding hardware can create the same hazard as bad hand-mixing if it is installed or maintained carelessly.
Identify the actual feed method
Different feeders fail differently and need different inspection points.
Treat storage and containment as part of the system
The tank area can be the most dangerous part of the installation.
Calibrate and verify output with testing
A feed pump is only trustworthy if the water test confirms what it is doing.
Know the stop conditions
Some symptoms mean owner-safe inspection is over.

Chemical Feeder Boundary
Chemical-dosing equipment is only owner-safe while the task stays on identification, containment, and documented calibration.
- ✓ Identify the feeder family, inspect tanks and tubing visually, and verify output with water testing.
- ✓ Prime and calibrate only by the documented manual procedure using compatible parts and fluids.
- ✓ Shut the system down and revert to manual chemistry if the feeder cannot be trusted.
- ★ Repair live wiring, corroded injection assemblies, advanced controller failures, or unclear acid-chlorine interlock behavior.
- ★ Redesign injection-point layouts, containment, or chemical-separation logic without the correct hardware guidance.
- ★ Continue service when fumes, leaks, or incompatible residues suggest the installation is unsafe.
- ⚠ You detect active acid or chlorine fumes, leaking tanks, crystal buildup from repeated leaks, or damaged wiring.
- ⚠ The only way forward would be bypassing a safety, improvising tubing compatibility, or mixing chemicals to keep the system running.
- ⚠ A controller or dosing pump is feeding unpredictably and you cannot prove output with testing.
