The vacuum breaker on an RV toilet's water inlet is a small but important part — it prevents water from being siphoned backward out of the bowl and into the fresh water system. When it wears out, it can cause leaks or backflow issues at the toilet.
Thetford's 19671 repair kit provides the parts needed to rebuild that vacuum breaker without replacing the entire toilet water valve, keeping the job quick and inexpensive.
A useful kit to keep on hand for RV toilet maintenance, especially if you're noticing leaks or backflow at the water inlet.
