Dometic 310 Toilet Leaking at Foot Pedal: Complete Fix Guide

Dometic 310 Toilet Leaking at Foot Pedal: Complete Fix Guide

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

How to Fix Stuck RV Toilet Valve After Winterization - Step by Step

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

Onan 4000 Generator Won't Start Without Choke: Code 14 Troubleshooting Guide

Halfway through another camping trip and trying to decide between babying my Onan 4000 with manual choke every startup or finally fixing this Code 14 nightmare. Let me try again:

Just found out that my 2013 Thor Class C's Onan 4000 generator won't cooperate after sitting since March, and I'm dealing with a nightmare. Been getting Code 14 errors and spent half the morning just trying to get it fired up.

The only way I can get it started is by manually messing with what I think is the choke linkage - otherwise it just won't go. Once I shut it off, same story - won't restart unless I physically manipulate that linkage again. Only has 240 hours on it and was serviced about 2 years ago.

I'm pretty sure the carburetor is gummed up from sitting, but what exactly does Code 14 mean? And more importantly, what do I need to clean to get that choke working automatically again? I really need to get this thing running properly before our next trip! …more

How to Fix Onan QD3200 Diesel Generator Fuel Leak Behind Air Filter

According to Murphy's Law, my Onan QD3200 generator is doing something bizarre — it's leaking diesel fuel from behind the air filter instead of where you'd normally expect fuel leaks. The fuel appears to be coming from somewhere behind the air filter box, and I'm worried about making things worse if I don't diagnose this properly. I've shut everything down for now because I'm nervous about safety issues.

I need to know the safest way to trace where this leak is actually coming from without creating a fire hazard or damaging anything. What are the most likely culprits in that area, and what's the proper procedure to identify the exact source? I want to make sure I approach this methodically rather than just poking around and potentially making the problem worse. …more

How to Travel with a Winterized RV: Complete Cold Weather Guide

I noticed my travel trailer isn't winterized for my Connecticut to Florida Keys trip in February — can't afford professional service right now, need DIY solutions under $200? I'll be stopping at my brother's place in New Jersey first, and then caravaning to our first stop in Fredericksburg, VA at a KOA with a full bathhouse.

I've winterized my travel trailer for the cold months up here, and I recently heard a podcast about travelers staying winterized and using RV antifreeze for quick bathroom needs during the trip. I'm wondering if anyone has experience with this approach.

I know I could de-winterize before leaving, but I'm worried about pipes freezing during the drive south since we'll be going through some cold states. On the other hand, traveling winterized means no water systems working during the trip. What's the smartest way to handle this? Should I keep it winterized for the whole drive and deal with no water, or is there a better strategy I'm missing? …more

Dometic 310 Toilet Foot Pedal Problems: When to Replace vs Repair Completely

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

Thetford Aurora Toilet Replacement Guide: Best RV Toilet Upgrades 2024

Thetford Aurora Toilet Replacement Guide: Best RV Toilet Upgrades 2024

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

Thetford Aria Deluxe 2 Toilet Blade Assembly Installation: Step-by-Step Guide

Finally picked up my RV last month only to discover the previous owner left the Thetford Aria Deluxe 2 toilet blade assembly completely botched and leaking everywhere. The replacement kit included multiple washers of different sizes, but the installation documentation lacks clear specifications for proper washer positioning.

I need to verify the correct placement sequence for the rubber washers - specifically which washer interfaces with the bowl surface and how the smaller washers should be positioned relative to the mounting hardware. The leak appears to be originating from the assembly-to-bowl junction, suggesting improper seal alignment during reassembly. …more

How to Replace Thetford Style II Toilet Ball Valve Seal Without Removal

Last weekend I followed three YouTube tutorials to fix my Thetford Style II toilet's water retention issue, but now the bowl drains even faster after flushing. Diagnostic assessment indicates the ball valve seal has deteriorated and requires replacement.

Before proceeding with repairs, I need to determine the most efficient approach. Is it possible to access and replace the ball valve seal without removing the entire toilet unit from its floor mounting? What access points are available for this type of seal replacement on the Style II model? …more

RV Toilet Won't Hold Water: Fix Bowl Drainage & Sewer Smells

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

How to Fix a Macerator Toilet Leaking Water From Bowl to Floor

Turned on my RV this morning to discover my macerator toilet is leaking water from bowl to floor — can't afford a $200+ service call, any DIY fixes under $50? We have a 2016 DS 3736 with a macerator toilet that just started leaking water from the bowl onto the bathroom floor. The RV has been sitting unused for about two months, and this is the first time we've had it out since then - not sure if that's related but thought I should mention it.

The leak started two days ago and water is coming out pretty quickly now. I'm wondering if sitting idle could have caused something to dry out or if there might be debris blocking something? I'd love to know how to figure out exactly where it's leaking from and what the most common fixes are for this type of issue. Any advice on troubleshooting steps would be really appreciated! …more

Dometic RV Toilet Parts Diagrams: Complete Guide by Model Number

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

Dometic Sealand Traveler 111 to 511 Toilet Upgrade Guide

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
