Fetechmate RV Toilet Replacement Valve Kit — 2-Set 385311641 Valves with 385311658 Flush Ball Seals for Dometic 300-321 Series, Le

Fetechmate's 385311641 valve and 385311658 flush ball seal kit is a 2-set OEM-compatible replacement that stops leaks and restores reliable pedal-flush operation for Dometic 300/301/310/311/320/321 series RV toilets.

When an RV or marine pedal-flush toilet drips, smells, or fails to hold vacuum, the most common culprits are worn valves and seals. This two-pack replacement from Fetechmate includes the 385311641 water valve assemblies and matched 385311658 flush ball seals, hardware, and filters to return your toilet to tight, odor-controlled performance without hunting for multiple parts. The kit is built from heavy-duty ABS, pressure-tested for sealing, and supplied with clamps and screws for fast installation.

How does this kit stop leaks and odors?

The kit uses an upgraded integrated sealing design plus precision-fit flush ball seals that block water seepage and prevent sewer gas backflow. Components are pressure-tested at the factory and the ABS valve bodies resist deformation under pedal pressure.

• Integrated sealing structure reduces valve-to-body gaps.
• 385311658 flush ball seals form a tight closure against the valve seat.
• Pressure-tested assemblies reduce the risk of post-installation drips.
• Included hose clamps ensure secure connections to inlet hoses.

This replacement set is engineered for mainstream RV and marine pedal-flush and vacuum-flush systems, matching common OEM dimensions for direct swaps. It’s ideal when the existing valve leaks, the pedal feels spongy, or the bowl won’t hold vacuum.
