Valterra's 3" valve body kit is a direct-replacement assembly for RV black-water tanks, including the valve body, seals, nuts, bolts and a plastic handle for fast swap-outs. Replacing a worn or leaking sewer valve doesn't have to mean lengthy repairs or a complete drain assembly overhaul. This 3" valve body from Valterra is designed to restore proper flow and sealing on compatible RV black-water systems quickly. It fits common valve brands and arrives with the small parts you need to complete the job in a single visit, saving time and avoiding multiple trips to the parts store.

Will this part fit my RV black-water tank valve?

Compatibility was a key design point. The replacement body fits Valterra units and is sized to match several other widely used valve brands so many RV owners can swap it in without custom adapters.

• 3" diameter flow passage sized for standard black-water lines
• Compatible with Bladex, Valterra, Bristol and Anonda valve configurations
• Includes mounting nuts and bolts to match existing installations

How easy is installation for a DIY RV owner?

The kit is made for straightforward field replacement: remove the old valve body, transfer or replace seals, fasten the new body, and reattach the handle. Basic hand tools and a short block of time are typically all that's required.

• Comes with all seals, nuts and bolts supplied
• Plastic handle pre-fitted for simple operation
• No specialty tools needed—common wrenches and screwdrivers suffice

What performance can I expect once installed?

With a full 3" internal diameter, the valve permits unobstructed waste flow when open, reducing backups and improving drain speed. New seals restore a water- and odor-tight closure when the valve is shut, helping preserve campsite comfort.

• 3" passage minimizes flow restriction when open
• Replacement seals reduce leakage and odor escape
• Durable construction made to withstand routine RV use

What parts are included and why they matter?

The kit bundles the valve body with the hardware needed to secure it and fresh seals to ensure a reliable connection. That means fewer missing components and a higher chance your repair is finished in one session.

• Valve body sized to replace worn originals
• Seals to restore tight closure and prevent seepage
• Nuts, bolts and a plastic handle to complete the assembly
