Results for "dometic toilet"

Called my weekend camping trip short because my Dometic 310 toilet has water pooling underneath, the flush mechanism sticking, AND that annoying gurgling sound happening constantly. I can see the leak between the fixed outer part and the moving pivot section when the pedal is pressed.

Already replaced the toilet valve but it's still leaking from the same spot. The inlet and outlet hoses look fine. What causes leaks at the pedal mechanism itself after the valve has been changed? …more

Somewhere between embarrassed and desperate, I have to ask this probably dumb question: why does my RV's black tank act full when it should hold way more? We have a 40-gallon black tank, but when I try to fill it with water for cleaning, it starts overflowing through the vent pipe at only 23 gallons. I'm afraid there might be something seriously wrong with the installation or that I could damage the system.

A professional cleaning service said the tank was completely clean with no blockages, so I'm confused about why it won't hold its full capacity. The water is definitely coming out the vent pipe, so I assume that means the vent isn't blocked? I'm hesitant to keep trying things without understanding what's actually causing this - could this be a safety issue or sign of improper installation? What should I be looking for to diagnose this safely? …more

Called a repair shop about my RV toilet valve that only gets stuck when it's above 60 degrees outside — works perfectly fine during colder weather after winterization. During the camping season, my toilet works perfectly fine - the dump valve opens and closes smoothly without any problems. However, after I winterize my RV for winter storage and drain all the water from the system, I consistently run into the same frustrating problem when I try to de-winterize in spring.

The toilet dump valve gets completely stuck in the closed position and requires significant force to get it moving again. It seems like the valve mechanism seizes up during the months of storage when there's no water in the system. I'm assuming this happens because the seals and moving parts dry out completely without any moisture present during winter storage.

What's the best preventive maintenance I can do to keep this valve from sticking during winterization? Are there specific lubricants or treatments I should apply to the valve mechanism and seals before putting the RV into storage? I'd rather prevent this problem from happening in the first place rather than having to force a stuck valve every spring and risk damaging the toilet. …more

Since moving into an RV with a Dometic 310 toilet, the foot pedal is acting up in ways I've never encountered before. The foot pedal mechanism has exhibited poor responsiveness, requiring multiple valve replacements over time. Despite these repairs, the pedal continues to malfunction with irregular operation patterns.

Given the recurring nature of this issue and the accumulated maintenance costs, I am evaluating whether to continue with component-level repairs or proceed with a complete toilet replacement. What factors should determine this decision, and at what point does full unit replacement become the more practical solution? …more

The minor drip from my Thetford Aurora toilet seals started last month but now it's turned into a constant leak requiring daily maintenance. After one seal replacement, the failure recurred within four months of operation, indicating a potential systemic issue with this model's design.

I'm evaluating replacement options and need technical guidance on reliable alternatives. Budget considerations are important, but I require a unit that can withstand continuous use without recurring maintenance issues. Preference is for ceramic bowl construction over plastic alternatives for durability and performance characteristics.

What are the most reliable Thetford toilet models for Aurora replacement, and how do budget options like the Aqua Magic series compare to mid-range and premium models in terms of long-term reliability and seal performance? …more

Since my RV service tech insists I need to replace my entire toilet just because the water keeps disappearing from the bowl, I'm wondering if he's overselling me on what might be a simple seal issue. Pretty sure it's a seal issue but not sure if it's the ball seal, blade seal, or something with the valve itself. Getting some lovely sewer smells too which is just fantastic 🙄

Before I start tearing things apart, what's usually the culprit here? And roughly what am I looking at cost-wise for parts? Really hoping this is one of those DIY fixes and not a "call the RV guy" situation. …more

Halfway through this camping season, my Dometic RV toilet is eating through replacement parts way faster than it should, and I can't figure out which diagrams match my model number. I think I need a new ball seal and possibly a water valve, but I want to make sure I get the right parts for my specific model.

Where can I find official parts diagrams that show all the components? Also, I'm not even sure how to figure out what model toilet I have - is there a way to identify the model number? Any guidance would be really helpful since I don't want to order the wrong parts. …more

Three days into my RV trip with the kids, my Dometic Sealand Traveler 111 toilet started leaking and making weird gurgling sounds during my 511 upgrade—is this dangerous? Both are low-profile toilets and my current setup has a 4-bolt floor flange.

Will the Traveler 511 bolt directly onto my existing mounting hardware without modifications? I want to confirm the mounting patterns are compatible before ordering the replacement. …more

Replaced my RV's exhaust manifold last month, but it only acts up when it's above 80 degrees outside — runs perfectly during cooler weather. Our 2014 Fleetwood Bounder 35k has what I think is an exhaust manifold problem, and our VacuFlush toilet system has completely lost suction.

I'm having trouble figuring out what type of shops or mechanics actually work on these specific RV systems. Are these the kind of repairs that regular RV dealers handle, or do I need to find specialized shops? I'm worried about taking it to the wrong place and getting told they can't help.

Any guidance on what types of service providers I should be looking for would be really appreciated. Thanks for helping out a newbie! …more
