When your pool’s chemical feeder isn’t working correctly, it can lead to inconsistent chlorine or sanitizer levels, turning a sparkling clean pool into a murky maintenance challenge. Whether you’re a homeowner in South Florida or manage a commercial aquatic facility, troubleshooting chemical feeder issues is essential for maintaining balanced water chemistry and a safe swimming environment.

At M&M Pool & Spa Services, we specialize in error diagnosis, resolving common problems, and providing expert fixes to restore your chemical feeders to proper working condition—before it affects your water quality and pool equipment.

Understanding How Chemical Feeders Work

Chemical feeders are automatic dosing systems that regulate the introduction of sanitizing agents like chlorine or bromine into your pool or spa water. These can include inline chlorinators, erosion feeders, peristaltic pumps, and digital chemical injection systems. A properly working feeder ensures water is consistently balanced, reducing manual labor and preventing algae growth, mineral scaling, and other chemical imbalances.

Types of Chemical Feeders

  • Inline Chlorinators: Installed in the return line after the filter.
  • Floating Feeders: Float in the pool and slowly dissolve tablets.
  • Peristaltic Pumps: Deliver precise amounts of liquid chemicals via adjustable flow.
  • Salt Systems (Chlorine Generators): Convert salt to chlorine via electrolysis.

The type of feeder you use determines the potential issues you might face, so it’s important to understand your system when beginning any error diagnosis.

Step-by-Step Chemical Feeder Troubleshooting

1. Identify Symptoms of a Malfunctioning Chemical Feeder

Typical signs include:

  • Cloudy pool water
  • Strong chlorine odor
  • Algae or scale buildup
  • Test kits show inconsistent pH or chlorine levels
  • The feeder is leaking, clogged, or not dispensing

2. Inspect Common Components

Chemical feeder issues often revolve around the following areas:

Clogs and Obstructions

Mineral buildup, tablet residue, or organic debris can clog your feeder lines or valves. If you notice a slow or halted chemical release, check the:

  • Internal tubing
  • Chlorine/bromine tablets for swelling
  • Inlet screen for debris

Valves and Dials Malfunctioning

Adjustable settings may break or become unresponsive due to wear, high UV exposure, or chemical corrosion. Replace damaged knobs or tighten any loose fittings.

Pump and Flow Rate Problems

For electronically controlled feeders like peristaltic pumps or salt systems, check:

  • That pumps are receiving power
  • Flow sensors are clean
  • Tubing is not kinked, collapsed, or leaking

Leaking or Cracked Housings

Plastic housings are prone to cracking over time. Look for water drips or chemical stains, which may suggest degraded seals or overtightened components.

Expert Fixes for Common Problems

Reset and Rebalance

Start by resetting the feeder to its default settings. Clean out the lines and refill with fresh chemicals. Ensure the pool chemistry is balanced using a test kit before restarting the feeder.

Replace Worn Parts

From o-rings and seals to feeder tubing and sensors, many internal components are inexpensive to replace and improve feeder reliability.

Update to a Smart Chemical Feeder

Modern digital feeders monitor water chemistry in real time and adjust dosing automatically. If your older model continues to fail, upgrading may save you time and costly chemical waste in the long run.
