Clack (C2250)-Retention Tank, 40 Gallon 21" x 42" RT40
Clack C2250 Retention Tank 40 Gallon
The Clack C2250 RT40 retention tank simplifies chemical feed installations with top-mounted IN/OUT connections and a complete 1190RT head assembly. Built with a black polyethylene liner inside a fiberglass shell, this 40-gallon tank includes an internal baffle diffuser for thorough chemical mixing and a full 1-inch bottom drain with 360° rotation for complete system drainage.
Integrated Retention and Mixing
Top-Mount Connection
Water and chemical enter through the 1190RT head with 1-1/4" × 1-1/2" PVC fittings. Convenient top piping eliminates floor-level connections and simplifies plumbing runs.
Baffle Diffusion
Internal baffle diffuser promotes thorough mixing of treatment chemicals with incoming water throughout the 40-gallon volume. Extended contact time ensures proper chemical distribution.
Dwell Time Storage
Black polyethylene liner resists impact and corrosion while grey fiberglass outer shell provides structural integrity up to 75 PSI and 120°F.
Full System Drainage
Top-mount outlet feeds treated water downstream while 1-inch bottom drain with 360° orientation allows complete tank evacuation for service and maintenance.
