Description

The Merrill 5-Inch WC Sanitary Well Cap is a durable wellhead cover designed to maintain a sanitary seal while accommodating service lines. Sized for a 5-inch casing, it provides a 1-inch conduit opening and a 3/4-inch vent to allow necessary access and ventilation for pumps and wiring. Constructed of painted cast iron with two neoprene O-rings and stainless steel bolts, the cap offers corrosion-resistant hardware and a reliable sealing interface. A galvanized vent ell with a stainless steel screen is included, and the cap is compatible with a custom name plate for identification. Use it where a robust, service-friendly well cap is needed for residential or light commercial well installations that require conduit and vent access.
