Hayward 9 lb In-Line Automatic Chemical Feeder (CL200EF)

Say goodbye to daily pool maintenance with the Hayward CL200EF In-Line Automatic Chemical Feeder. Designed to seamlessly integrate directly into your pool's existing filtration system, this heavy-duty chlorinator automatically dispenses a precise, continuous stream of sanitizer to keep your water crystal-clear and safe.

With a massive 9 lb capacity chamber, the CL200EF holds up to two weeks' worth of slow-dissolving Trichlor or Bromine tablets or sticks. It is the perfect maintenance-free solution for busy pool owners who want to spend more time swimming and less time handling chemicals.

Why Choose an In-Line Feeder?

An in-line model is glued directly into your main 1.5-inch return plumbing line, right after your filtration system (and heater, if applicable). Because it requires no external hoses or tubing, it creates a cleaner, more permanent layout on your equipment pad with zero external clutter. It is ideal for new pool construction or equipment upgrades where you have room to cut into the PVC line.

Key Features

• High-Capacity 9 lb Chamber: Holds up to 18 large 3-inch tablets or sticks, providing weeks of automated sanitation for large residential and commercial pools up to 100,000 liters.
• Precision Control Dial: The integrated control valve allows you to easily adjust the water flow through the chamber, giving you precise command over your chlorine or bromine feed rate to keep levels perfectly balanced.
• Easy-Lok™ Threaded Lid: Features an ergonomic threaded cover for quick, tool-free access during refills. The integrated finger-release catch provides a built-in locking mechanism for extra security.
• Rugged, Corrosion-Proof ABS Body: Constructed from high-density, commercial-grade ABS thermoplastic paired with a premium Viton® seal to prevent leaks and withstand aggressive chemicals or harsh UV rays.
• Internal Backflow Check Valve: Features a built-in non-return check valve designed to prevent concentrated chemical gases from flowing backward through your plumbing, protecting your filter and heater from corrosion when the pump is off.

⚠️ Safety Notice: This unit is engineered to run exclusively on slow-dissolving stabilized Trichlor (or Bromine) tablets or sticks. NEVER mix different types of chemicals (such as mixing Trichlor with Calcium Hypochlorite or granular shock), as doing so can trigger a violent chemical reaction, fire, or gas explosion. Always turn off the pool pump and let pressure bleed off before opening the lid.
