Valterra 1 1/2" Dump valve RV Drain Sewer Waste Valve

This Valterra T1001-style assembly provides a simple, heavy-duty connection for RV drain and sewer systems where a 1 1/2" slip hub mates to a 1 1/2" spigot flange. Built for common RV plumbing layouts, the valve lets you join different fitting types without complex adapters, helping maintain a leak-resistant, serviceable waste line. It replaces worn or damaged dump valves and integrates with standard RV sewer hose and flange components.

How does this valve fit into my RV plumbing?

The assembly bridges a 1 1/2" slip hub on one side to a 1 1/2" spigot flange on the other, matching common RV drain dimensions. It installs inline at the trailer’s waste outlet and works with standard sewer hoses and flanges to route black or gray water away from your vehicle.

• Accepts 1.5" slip hub connections for secure push-fit attachment
• Spigot flange end mates to 1.5" female fittings or hose cuffs
• Designed for direct replacement of worn dump valves
• Compact footprint for tight undercarriage spaces

What materials and durability can I expect?

The valve uses rugged materials suited for routine RV waste handling and exposure to outdoor conditions. Components resist common wear points and provide a longer service life than thin, generic fittings, while remaining lightweight for RV applications.

• Robust body for repeated open/close cycles
• Corrosion-resistant surfaces for outdoor use
• Sealing edges engineered to reduce leaks at connections

How easy is installation and maintenance?

Installation is straightforward for most RV owners with basic tools: slide the hub end and secure the spigot flange with standard clamps or bolts. Maintenance is minimal — periodic inspection and replacement of clamps or seals keeps the assembly functioning reliably.

• Simple slip-fit and flange connections—no custom fabrication
• Accessible design for quick replacement under the RV
• Compatible with common hose clamps and mounting hardware

Will this work with my existing sewer hose and fittings?

Yes—this assembly is intended to integrate with typical RV sewer hoses and flanges sized at 1 1/2". Confirm that your hose cuffs and inlet accept 1.5" spigot or hub dimensions for a proper seal before installing.

• Matches standard 1.5" RV hose and flange dimensions
• Works with clamp-style or bolted flange attachments
• Compatible with most aftermarket sewer hose systems

Who is this for: RV owners, fleet managers, and service technicians who need a dependable 1 1/2" hub-to-spigot dump valve replacement. It’s especially useful for anyone upgrading a worn outlet, simplifying plumbing transitions between fittings, or keeping a compact, durable valve on hand for field repairs.
