Dometic Traveler 510+ RV Toilet Parts & Exploded Diagram

The Dometic Traveler 510+ is a foot-pedal RV toilet with a ceramic bowl and a separate pedestal base. The water valve, flush-ball seals, pedal components and seat can be serviced without choosing an entire replacement toilet. This guide pairs Dometic's numbered parts drawing with matching replacement items available from UsedRVParts.

Check the complete toilet model on the base label before ordering. The 510+, 510H and 511 share some service parts, but their base, pedal and sealing assemblies are not all the same.

Water valve or vacuum breaker?

The 385314349 water valve regulates incoming water when the flush pedal is used. If water continues running after the pedal is released, inspect the valve and its operating linkage. The 385316906 vacuum breaker is part of the bowl supply connection and serves a different purpose. Choose by the component and number on your original toilet rather than by the symptom alone.

Flush-ball seals versus floor seal

If water slowly disappears from the bowl, check the flush ball and its sealing surfaces. The 385311462 kit contains the replacement flush-ball seals shown at position 7. The 385310063 floor/base seal, at position 16, seals the lower mounting connection. These kits repair different locations and should not be substituted for each other.

Seat and foot-pedal parts

The 385343829 seat and cover is the white option for this toilet. The corresponding bone-coloured seat is 385343831. Match the original seat shape and hinge placement as well as the colour. The 385310114 white pedal cover is the outer pedal piece; the internal pedal/cartridge kit and spring cartridge have their own part numbers in the table.

Other parts and compatible versions

Dometic's drawing also identifies the ceramic bowl, base-to-bowl clamp, supply hose, pedestal cover and mounting hardware. The optional hand-sprayer system has its own vacuum breaker and hose. These assemblies should be chosen according to the exact model and whether the sprayer is fitted.

For an earlier manufacturer service reference, see the Dometic sanitation replacement-parts guide. If your toilet is a plastic-bodied Dometic 300, 310 or 320, use our Dometic 300/310/320 toilet parts guide instead.

Shut off the RV fresh-water supply and relieve water pressure before servicing valves or hoses. Follow the manufacturer's installation instructions when reassembling seals, floor hardware and water connections, then check for leaks.
