The CARSON 12204001 is a replacement jumbo lid designed for Carson T-Cover valve boxes used in irrigation, water service, and utility applications. This lid serves as the top closure for underground valve box installations, providing access to shutoff valves, curb stops, and other buried service components. The green color designation follows common industry convention for non-potable irrigation service identification. Licensed irrigation contractors, plumbers, and utility crews typically stock replacement lids separately to address cracked or missing covers without replacing the full box assembly.
This lid is suited for residential and light commercial irrigation systems, water meter pit installations, and utility valve access points where a jumbo-size T-cover box is already in place. It is a direct replacement component for the corresponding Carson jumbo T-cover box body, making it a practical service part for contractors maintaining existing installations.
Designed as a replacement lid for Carson jumbo T-cover valve box assemblies used in irrigation and utility service installations.
Installation is performed by irrigation contractors, plumbers, or utility technicians servicing existing underground valve box assemblies. Shut off any active irrigation zones or water supply before accessing the valve box. The lid should seat fully and flush with the box rim to prevent soil intrusion and maintain safe ground-level clearance. Local codes may govern burial depth and box placement — consult applicable plumbing or irrigation standards for the jurisdiction.
