Compatibility & Fitment

This valve kit fits Dometic and Sealand pedal-flush toilets in the 300, 301, 310, 311, 320, and 321 series. It is suitable for compatible toilets installed in campers, travel trailers, motorhomes, and marine applications. Check the existing valve, seal, and toilet model before ordering.

When to Replace

Replace the valve and seal when the toilet shows signs of a worn water valve or flattened flush ball seal, including:
  • Water leaking from the valve body or hose connection.
  • Water continuing to run after releasing the flush pedal.
  • A weak or slow flush.
  • A loose pedal button.
  • Odors entering the bowl from the holding tank.

Installation Tips

Installation takes about 15 minutes with basic hand tools. Shut off the water supply and drain the line before removing the old parts.
  1. Remove the old valve and lift out the worn flush ball seal.
  2. Press the replacement valve into position and tighten the two mounting screws evenly.
  3. Slide the water pipe onto the top port and secure the water line with the hose clamp.
  4. Install the replacement seal beneath the flush ball.
  5. Run a test flush and inspect the valve and hose connections for leaks.
