When it comes to dependable pool sanitization, Jandy’s TruChlor™ Erosion Feeders stand out for their simplicity, efficiency, and flexibility. Whether you're maintaining a residential pool or a light commercial system, the TruChlor family offers three distinct models designed to match your plumbing configuration and pump system. Let’s break down what each model offers and help you choose the right feeder for your setup.
What is an Erosion Feeder?
An erosion feeder is a type of chlorinator that slowly dissolves solid chlorine tablets—typically trichlor or cal-hypo—into the pool’s water as it flows through the feeder. These systems are preferred for their low-maintenance design and ability to deliver steady chlorine dosing without requiring electricity or complicated programming.
Jandy's TruChlor™ line brings this concept to life with modern construction, easy maintenance features, and options for both inline and offline installation.
Jandy TruChlor™ Erosion Feeder – Standard Inline | TCLINCG
The standard inline model is the workhorse of the TruChlor™ lineup. Installed directly into your return plumbing line, it offers continuous sanitization with minimal effort.
Key Features:
-
Built-in clear glass lid for visual tablet checks
-
Durable corrosion-resistant housing
-
Compatible with 1.5” and 2” plumbing
-
Holds multiple 3” tablets for extended runtime
-
Locking the lid ensures safety and secure operation
Best For:
Pool owners who are looking for a direct-flow chlorination method with low visibility and consistent output. It’s ideal for residential pools where plumbing lines are accessible and space is limited.
Jandy TruChlor™ Offline Erosion Feeder, Base with 2″ Clamp | TCLOFFCGB20
