WEHOPE RV Toilet Flush Ball & Shaft Cartridge Kit 385310681 — Fits Dometic/Sealand, Includes Spring & Screws

If your RV toilet is leaking, failing to seal, or producing persistent odors, replacing the flush ball assembly and shaft cartridge is a common, economical repair. This WEHOPE kit contains the parts you need to renew the sealing mechanism on many Dometic/Sealand plastic-pedal toilets, helping the toilet close tightly and operate smoothly again without replacing the entire fixture.

Which Dometic or Sealand models will this kit fit?

This kit matches numerous Dometic/Sealand toilet model numbers that use a plastic foot pedal and the same sealing geometry. It replaces OEM part number 385310681 but is not compatible with the 300, 310, or 320 series toilets.

• Compatible with models such as 110, 130, 147, 148, 209, 210, 248 and more.
• Works for many 5000‑series and 1000‑series Dometic/Sealand models listed in the fitment.
• Verify your existing part number or compare the shaft and ball design before ordering.

How do I install the WEHOPE flush ball and shaft cartridge?

Installation is straightforward for anyone comfortable with basic RV maintenance: remove the old flush ball assembly, swap in the new shaft and spring cartridge, and reattach the fasteners. No special tools are required beyond a screwdriver and basic hand tools, but confirm there are no remaining leaks after installation.

• Remove the toilet access panel and unfasten screws holding the existing cartridge.
• Pull out the old flush ball and shaft, insert the new cartridge and spring, then secure with included screws.
• Test the pedal action and inspect for leaks; tighten screws if necessary.

What parts are included and why they matter?

The kit contains a replacement flush ball, a shaft kit, a spring cartridge, and four screws—everything required to rebuild the sealing and actuation components. Replacing all related pieces at once helps ensure a consistent seal and reduces the chance of repeat leaks caused by mismatched old and new parts.

• One flush ball: restores the toilet bowl seal to prevent odors and leaks.
• One shaft kit and spring cartridge: reestablishes smooth pedal-to-valve linkage.
• Four screws: secure the cartridge in the correct position for reliable operation.

Will replacing these parts stop bad smells and leaks?

Replacing a degraded flush ball and worn shaft components often eliminates odors and stops leakage originating from the seal or faulty actuation. If smells persist, check the holding tank, venting, and seals elsewhere; this kit addresses the bowl-to-tank seal specifically.

• Fixes seal-related leaks around the bowl closure point.
• Improves pedal response so the valve closes fully after each flush.
• Combine with routine tank maintenance for best odor control.

Who this is for: RV owners and technicians with Dometic/Sealand plastic-pedal toilets needing a cost-effective repair to restore sealing and flush performance. Choose this kit if your toilet matches the listed models and shows signs of leakage, incomplete closure, or lingering odors; it’s aimed at DIYers and service shops seeking a full replacement cartridge package without buying an entire toilet assembly.
