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

Just found out Norcold filed for bankruptcy and now I'm sitting here with a fridge that needs a cooling unit replacement. Dealer says parts might not be available much longer and is pushing me to switch to Dometic. How worried should I actually be about getting Norcold parts and service going forward? …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

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

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

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
