The CAMCO MFG 39513 is a 3-inch sewer waste valve designed to control the flow of wastewater in RV sewer systems. Fitted with a plastic handle for manual operation, this valve provides a reliable shutoff point between the holding tank and the sewer connection. The E/F designation indicates it is configured for standard RV waste outlet applications. Plumbers and RV service technicians install this valve as a direct replacement or new-install component on recreational vehicle waste systems where a 3-inch gate valve is required.
This valve is suited for residential-style RV waste plumbing where a durable, manually operated gate valve is needed at the tank outlet. It is a common service item on Class A, Class B, and Class C motorhomes as well as travel trailers and fifth wheels equipped with 3-inch sewer outlets. The plastic handle design keeps weight low and resists corrosion in wet waste environments. It is typically installed by RV technicians or knowledgeable owners during holding tank maintenance or valve replacement service.
Designed as an OEM-style replacement waste valve for RV sewer systems requiring a 3-inch gate valve with a plastic handle at the holding tank outlet.
Installation should be performed with the holding tank fully emptied and the sewer connection disconnected. Wear appropriate personal protective equipment when working on waste plumbing. Ensure all upstream tank valves are closed before removing the existing valve. Follow applicable plumbing codes and RV manufacturer service guidelines when replacing waste system components.
