Symptoms of a Failing Water Valve
- Water runs continuously or trickles into toilet bowl when not in use
- Very weak flush — water barely enters bowl when pedal pressed
- No water at all when pedal is pressed
- Water leaking from valve body or connections
- Unusual hissing or vibrating sounds during flush cycle
- Toilet fills slowly — taking 30+ seconds for normal water level
Installation Guide
- Shut off RV water supply (turn off pump and disconnect city water connection).
- Flush toilet to relieve any remaining line pressure.
- Disconnect water line from valve inlet — press quick-connect release tab and pull.
- Remove mounting screws securing old valve to toilet base.
- Install new 385314349 valve assembly. Align mounting holes and tighten screws.
- Push water line into quick-connect fitting until it clicks — no tools required.
- Turn water supply back on. Cycle flush pedal several times to purge air.
- Inspect all connections for leaks. Adjust if needed.
Frequently Asked Questions
Q: My toilet keeps running — will this fix it?
A: Yes, if water is continuously flowing into the bowl even when the pedal isn't pressed, the internal valve diaphragm has failed. Replacing the complete valve assembly is the proper repair.
Q: Does this fit the Traveler 511 toilet?
A: Yes. The 385314349 fits all Sealand Traveler series models (110, 111, 210, 211, 510, 511) with push-to-connect water fittings.
Q: Do I need special tools?
A: No. The quick-connect fittings are tool-free. You'll only need a screwdriver for the mounting screws. Complete installation typically takes 20-30 minutes.
Q: Will this work with my well water / hard water system?
A: Yes. The valve is designed to handle mineral-heavy water. The built-in inlet screen catches sediment and can be cleaned periodically to maintain flow rate.
Q: Is this valve anti-siphon?
A: Yes. The integrated check valve prevents backflow into your fresh water system, meeting RVIA plumbing standards for toilet water supply connections.
Q: What causes water valve failure in RV toilets?
A: The most common causes are mineral scale buildup jamming the diaphragm, chemical degradation of internal seals from holding tank treatments, freeze damage in un-winterized systems, and simple wear from years of use.
