YAOAWE RV Toilet Valve Kit 385311641 2-Pack for Dometic 300/310/320 Series — ABS valves, seals & filters

YAOAWE 2-Pack 385311641 RV Toilet Valve Kit is a complete replacement set designed to restore reliable flushing and leak-free sealing on compatible Dometic 300, 301, 310, 311, 320 and 321 series RV toilets.

If your Dometic-series RV toilet is dripping, failing to hold water, or the flush feels weak, replacing the valve and seal assembly is a common and effective fix. This kit bundles two ABS plastic toilet water valves, matching seals and extras so you have spares for future maintenance. The components use antifreeze-treated materials meant to resist low-temperature stiffening and provide long-lasting sealing in mobile environments.

What parts are included and why do they matter?

The YAOAWE kit includes everything needed to replace both valves on two toilets or keep a spare on hand: two toilet water valves (385311641), two flush ball seals, two hose clamps, four screws and four stainless steel mesh filters. Each piece supports proper operation—valves control water flow, seals stop leakage, clamps secure hoses and filters prevent debris from clogging the system.

• 2x ABS toilet water valves (385311641) for main flow control
• 2x specially-treated rubber flush ball seals to prevent water loss
• 2x hose clamps and 4x screws for secure mounting
• 4x stainless steel mesh filters to catch particulates and extend service life

How do I know this fits my Dometic RV toilet?

This kit is specifically designed to fit the Dometic 300, 301, 310, 311, 320 and 321 series toilets. Because many RV valve assemblies look similar but are not interchangeable, confirm your toilet model number before ordering. Check your owner’s manual or the label on the toilet base for the series number to ensure compatibility.

• Fits Dometic 300/301/310/311/320/321 series toilets
• Compare part numbers (385311641 / 385311658) with your existing valve and seal
• Refer to your RV toilet manual or model plate for verification

How do installation and maintenance work?

Installation is a straightforward mechanical swap: remove the old valve, replace the seal and tighten clamps/screws. The kit includes filters and spare screws so you can fasten a clean, secure connection. If you encounter a small post-install drip, pressing the valve bottom a few times can help seat the flush ball seal properly.

• Basic hand tools required (screwdriver, pliers)
• Replace old valve, install new seal, attach hose with provided clamp
• Use included filters to reduce clogging and ease future cleaning

What performance improvements should I expect?

After replacing worn valves and seals, the toilet should stop unintended leaks, achieve more consistent water levels and restore firmer flush performance. The antifreeze-treated rubber and high-grade ABS construction help retain flexibility in cooler temperatures and resist warping or cracking under normal RV conditions. Keep the spare parts for quick field repairs to minimize downtime on the road.

• Reduced leaking and improved water retention
• More consistent flush strength and reliability
• Durable materials resist temperature-related stiffness and wear

Who is this for: The YAOAWE 2-Pack 385311641 RV Toilet Valve Kit is aimed at RV owners, technicians and fleet managers who operate Dometic 300/301/310/311/320/321 series toilets and need a dependable, service-ready replacement. It’s a practical choice for those who want a full, ready-to-install set with spare clamps, screws and filters included—especially useful for seasonal storage, cold-weather use or when performing preventative maintenance before a long trip.
