Xastro RV Toilet Flush Pedal Replacement for Dometic 300/310/320/321 — One-Piece Injection-Molded PP, Corrosion-Resistant

If your RV toilet pedal is cracked, loose, or no longer triggers a complete flush, this Xastro replacement pedal kit gives you a fast, durable fix without replacing the entire toilet. Engineered from high-strength polypropylene and injection-molded as a single robust piece, it resists corrosion and everyday wear better than ordinary plastics. The kit arrives with all parts and simple instructions so most owners can finish installation in about five minutes using only a screwdriver.

How does this replacement pedal match Dometic 300/310/320/321 toilets?

The Xastro pedal is made to align with the mounting points, spring tension, and travel of common Dometic 300-series mechanisms, so it engages the flush assembly properly. The fit is designed to avoid extra trimming or modification for most standard installations.

• Direct compatibility with Dometic 300/310/320/321 models
• Mounting holes and pedal profile match factory geometry
• Torsion spring supplied to mirror original pedal action

Why choose the upgraded PP injection-molded build instead of a cheaper option?

Xastro uses premium polypropylene and injection molding to create a one-piece pedal that resists cracking, UV exposure, and chemical contact better than lower-cost 3D-printed or brittle plastics. That translates into longer in-service life and fewer replacements over years of RV use.

• Injection-molded one-piece construction for greater strength
• 3x more durable than typical commodity plastics
• Corrosion-resistant material suitable for humid RV bathrooms

What comes in the kit and how easy is installation?

The kit includes everything needed for a straightforward swap: the pedal main part and upper cover, a torsion spring, PVC suction cup, Phillips screw, dual-use screwdriver, gloves, and a product manual. Installation is designed to be completed using only the supplied screwdriver and basic guidance in roughly five minutes for most users.

• Complete accessory set—no additional parts required
• Step-by-step manual and tools included for a quick swap
• No professional plumber or complex disassembly needed

How does this replacement save money and reduce hassle long term?

Replacing a worn pedal with the Xastro kit costs a fraction of a full toilet replacement and avoids downtime and complicated plumbing work. The durable materials and solid construction reduce the likelihood of repeated failures, so you spend less time on maintenance and more time enjoying your travels.

• Up to ~80% savings compared to full toilet replacement
• Durable design cuts frequency of future replacements
• Fast installation minimizes RV downtime
