The ASHLAND WATER GROUP WC622 is a 6-inch cast iron well cap designed to seal the top of a well casing in submersible pump installations. Its primary function is to prevent surface drainage, debris, insects, and contaminants from entering the well bore. Cast iron construction provides the durability required for long-term outdoor exposure in residential and light commercial water well systems. This component is typically installed by licensed well drillers, pump contractors, or plumbers servicing potable water systems.
The WC622 is suited for submersible pump applications where a secure, contamination-resistant well seal is required. It fits 6-inch well casings and is appropriate for residential water supply wells. The cast iron material resists physical damage and provides a stable mounting surface for wiring and drop pipe penetrations common in submersible pump setups.
Designed as an OEM-style replacement or new-installation well cap for 6-inch diameter well casings used in submersible pump applications.
Installation should be performed by a licensed well driller, pump contractor, or plumber in accordance with local well construction codes and applicable IPC guidelines. Disconnect and lock out power to the submersible pump before removing or replacing the well cap. Ensure all wire and pipe penetrations through the cap are properly sealed to maintain sanitary well conditions. Do not overtighten fasteners on the casing to avoid damage to the cap seating surface.
