Xastro RV Toilet Flush Pedal Replacement for Dometic 300/310/320/321 — Reinforced PP & Torsion Spring Kit

Replace a worn RV toilet foot pedal with a durable Xastro upgrade engineered to fit Dometic 300/310/320/321 models and restore reliable flushing in minutes.

If your Dometic RV toilet pedal is cracked, loose, or no longer actuating the flush, this Xastro replacement pedal provides a cost-effective, long-lasting fix. Made from reinforced polypropylene with a one-piece injection-molded design and supplied as a complete kit, it’s built to resist corrosion, repeated foot pressure, and the vibrations of life on the road. The set arrives with everything needed to swap pedals quickly—no plumbing expertise required—so you can avoid the expense and downtime of replacing the whole toilet assembly.

How does this pedal restore flushing performance?

Installing the Xastro pedal returns proper mechanical action to your Dometic toilet by replacing worn linkage and the broken foot surface that no longer depresses effectively. The thicker, reinforced PP body keeps the pedal aligned under load, while the torsion spring provides consistent rebound so the valve opens and shuts cleanly.

• Injection-molded one-piece pedal for stiffer, more reliable operation
• Torsion spring included to restore original tension and return
• Corrosion-resistant materials prevent seizing in wet environments
• Designed to match Dometic 300/310/320/321 mounting points

What’s included and how simple is the installation?

The Xastro kit ships with all parts required for a direct swap: the main pedal and upper cover, a torsion spring, suction cup, a Phillips screw, a dual-head screwdriver, gloves, and a step-by-step manual. Typical installation takes about five minutes and only needs the provided screwdriver—no special tools or complicated disassembly of the toilet are necessary.

• Full accessory pack prevents trips to the hardware store
• 5-minute replacement: remove old pedal, align new unit, tighten screw

How durable is this replacement pedal compared to stock parts?

Xastro uses premium-grade polypropylene that resists cracking, UV, and corrosion, offering roughly triple the durability of common replacement plastics. Its injection-molded construction is stronger than typical 3D-printed parts, reducing the chance of breakage from repeated foot pressure or rough road movement.

• High-strength PP for long-term wear resistance
• One-piece molding reduces weak joints and failure points
• Engineered to withstand RV vibration and frequent use
• Cost-saving alternative to full toilet replacement
