The WATCO IMI-34 is a metered water softener designed for residential water treatment applications where iron and hardness removal are required. Equipped with a Clack control head and the 2P100IMIX resin blend, this unit automates regeneration cycles based on actual water usage rather than a fixed timer schedule, reducing salt and water consumption. The system ships at 104 pounds and measures 22 inches by 43 inches, making it a full-sized, floor-standing unit suited for utility rooms or mechanical spaces. Licensed plumbers and water treatment technicians are the typical installers for this type of equipment.
This softener is configured with a Rust Handler media package, making it appropriate for water supplies that carry elevated iron content alongside general hardness minerals. The metered Clack valve head tracks volume throughput and triggers regeneration only when needed, which suits households or light commercial settings with variable daily water demand. The 1-cubic-foot resin capacity positions this unit for single-family residential service or similarly sized demand loads.
Designed as an OEM-style metered water softener replacement or new installation unit for residential water treatment systems requiring iron and hardness reduction.
Installation should be performed by a licensed plumber or certified water treatment professional in accordance with applicable local plumbing codes and IPC guidelines. Shut off the main water supply and depressurize the system before making any connections. Ensure adequate floor drain access for regeneration discharge and verify bypass valve operation before placing the unit into service. Do not overtighten compression fittings on the Clack valve head inlet and outlet ports.
