385230325 RV Toilet Vacuum Breaker Kit — Hand Sprayer — Stop Leaks & Prevent Backflow
A leaking vacuum breaker on your RV toilet doesn't just waste water — it can siphon contaminated water back into your fresh water system, cause odors, and damage your bathroom floor. The iFJF 385230325 Vacuum Breaker Kit is the correct dual-port replacement for Dometic/Sealand Traveler and VacuFlush toilets equipped with a hand sprayer. Unlike single-port alternatives, this kit includes the dedicated sprayer connection port — no adapters, no leaks, no compromises. Complete kit includes vacuum breaker body, integrated dual-seal check valve, all O-rings and gaskets, and stainless steel mounting hardware. Measures 3.25" L × 1.73" W × 3.65" H for exact drop-in fit.

Symptoms of a Failed Vacuum Breaker
- Water leaking or spraying from behind the toilet pedestal — especially when the hand sprayer is used
- Continuous slow drip from the breaker housing
- Bowl fails to hold water after flushing
- Sewage odor near the toilet (backflow through failed check valve)
- Reduced sprayer pressure or water hammer when flushing
Installation Steps
- Shut off water supply to the toilet.
- Flush to relieve system pressure.
- Disconnect the hand sprayer hose and water supply line from the old breaker.
- Remove the old vacuum breaker (typically 2 screws or threaded collar).
- Clean mounting surface and inspect for cracks or damage.
- Install new breaker with supplied gaskets — 2-3 wraps of Teflon tape on threaded connections.
- Reconnect sprayer hose and water line, turn on supply, test all connections for leaks.

Frequently Asked Questions
Q: Does this fit toilets without a hand sprayer?
A: No. If your Sealand/Dometic toilet does NOT have a hand sprayer, you need the 385316906 (single-port) vacuum breaker kit. This 385230325 has a dedicated sprayer port.
Q: How long does installation take?
A: 20-30 minutes. Accessing the back of the toilet in tight RV bathrooms is typically the most time-consuming part. A compact mirror and headlamp make it easier.
Q: Do I need thread sealant or Teflon tape?
A: Yes. Apply 2-3 wraps of Teflon tape to male threaded connections. Do not use pipe dope or liquid sealants — they can degrade the nitrile seals.
Q: Why does my breaker leak only when I use the hand sprayer?
A: This is a classic sign of a failed check valve inside the vacuum breaker. The sprayer back-pressures the system, and a worn seal can't hold. Replacement is the fix.
Q: Will this stop sewage odors?
A: If the odor is from backflow through a failed vacuum breaker — yes. If caused by a failed floor flange seal or holding tank vent, those may need separate repair.
