There is always seems to be something in an RV that needs repaired, replaced, or worked on. Our toilet has leaked for a few months now. It wouldn’t happen all the time but when you’d press the pedal down partway to fill the bowl you could hear the water hitting the floor. We discovered the Vacuum Breaker was leaking on our Thetford Aqua Magic Style II Toilet.

Vacuum Breaker Replacement
Replacing the vacuum breaker on the Thetford Aqua Magic Style II Toilet is one of the easiest jobs you could ask for. It should take you no longer than 30 minutes including removing and replacing the toilet to complete this task.
- 1/2″ Combination Wrench
- Thetford Vacuum Breaker Kit Part Number 34122 (Kit contains Vacuum Breaker assembly P/N 34313, Clamps (4) P/N 19541, Flush hose P/N 34377, and Flange Seal P/N 02125)
- Turn off the water in your RV and open a valve at a sink to drain any residual pressure.
- Press foot pedal all the way down to flush the water from the bowl.
- Remove the water hose that attaches to the back of your toilet.
- If your toilet has caps over the mounting bolts remove them and set a side.
- Remove mounting nuts.
- Carefully lift the toilet from the flange and move to a place to perform the vacuum breaker replacement. (We chose our shower.)
- Using plyers grip the hose clamp on the lower hose from the vacuum breaker and slide it away from the toilet.
- Pull the hose off the toilet.
- Next grip the hose clamp behind the vacuum breaker that goes into the toilet and slide it toward the breaker.
- Pull the hose off the toilet and the vacuum breaker should come free.
- Using the parts in the kit install the new hoses and clamps to the vacuum breaker.
- Reinstall vacuum breaker in reverse order.
- Change out toilet flange seal on bottom of toilet.
- Reinstall toilet in reverse order ensuring not to overtighten nuts.
Other Repairs We’ve Done

After traveling in our RV for 2 years and 7 months through 39 states one of our biggest fears came to fruition. A slide on our 2019 Thor Challenger 37YT got stuck while we tried to set up in Fargo, North Dakota. We’ve heard the nightmares of Schwintek Slide System Issues, and it caught up to us.
RV manufacturers use the cheapest materials and cost-cutting measures to build a motorhome. Some of their work is in my opinion on the shoddy side. See our Step Repair here.
A small squeak started coming from the fireplace. It wasn’t too bad to start with and would come and go. You know how a constant noise can really drive you crazy? A month later the squeak was back and this time it was not going away… It constantly squealed and seemed to eat at my soul. Check out our Electric Fireplace Squeak repair.
This super easy repair item is something you shouldn’t be afraid to do yourself if you’re an RVer. It only takes a few minutes to remove and replace a leaking vacuum breaker. Give it a shot if yours is leaking.
