Our black tank was overfilled during a dump/rinse. We had water pouring out the bottom of the camper. Is there a valve/seal or have we broken the tank?

First, sorry for your situation. Tough deal for sure. My belief is that the tank has an overflow valve to protect the tank from bursting. You just end up with a mess to clean up instead of having to replace or repair.

Does an RV Black Tank Have an Overflow? Written by Mike Gilmour in RV Guide
For those of you out there that are new to this RV life, we are going to answer an important question for you. Knowing whether or not a black tank has an overflow is going to make RVing much easier.
Does an RV black tank have an overflow? No, an RV black tank does not have an overflow. There is nowhere for the waste to go if the tank is full; that won’t cause an issue. If your black tank gets too full, there are three things that can happen.
1. The waste can back up the vent pipe and end up on the roof. 2. The waste will end up overflowing onto the bathroom floor. 3. The black tank will burst (this option is going to be expensive to fix).
While we know that none of this sounds glamorous, it is important to have a clear understanding of the RV waste system.

I stand corrected and humbly apologize for my incorrect post.

I notice when I'am dumping my black tank and rinsing at the same time that my black tank monitor constantly says full. So I don't know if my black tanking is dumping faster than the rinse water I'm adding? I think it's the spray of the rinse that fools the sensors of thinking it's full. I have to stop and start the rinse cycle and check the monitor for levels and repeat.

I have to stop and start the rinse cycle and check the monitor for levels and repeat. The rinse should never keep up with with the tank dump flow rate. If it does then you have problems with a backup somewhere or valves not opening all the way. Forget about the sensors. Mine quit working correctly the first or second time I filled the tank. Once debris get on the sensors they're useless. Mine haven't worked right for 5 yrs now. I can tell when full from looking down toilet when flushing or it'll make a slightly different sound when flushed.

I have to stop and start the rinse cycle and check the monitor for levels and repeat. A slurry forms as the toilet paper "disintegrates". As the tank drains, the wet slurry coats the tank walls with a wet mat, connecting the level "sensors". Mine always reads full because the wet poo mat allows a small electrical current to flow between the tank level contacts. Rinsing just rewets the mat. The tank walls will never dry out without air flow, and the small covered vent opening is 8 to 9 feet above the tank.

I can tell when full from looking down toilet when flushing or it'll make a slightly different sound when flushed. You are correct while dumping and using the saniflush the spray of the water inside the black take is soaking the sensor and they will ready full. Since I have like most a water pressure valve on my water line at the outside water spigot I know that I will usually get the same amount of water going into there black tank flush system. I gauged my water intake by running the water flush for 60 seconds. I turn off flush and check my tank level. if its still under 1/3 full I will run the flush for another 60 seconds. Whey I reach 1/2 full I will pull the dump handler again. Repeat, repeat, repeat several times. I only doing this when leaving the last rv park and heading home and putting trailer in storage.I once got distracted while rinsing and left the park to only get a call from the park manager that a neighbor reported that water was pouring out of my door. I completely flooded the trailer from end to end with all heat ducs full of water and all carpet soaked. I'll never do that again. SO don't get distracted while dumping and rinsing. I had closed the tank dump valve and add the rinse going on and left. The water had no where to go when the tank was full, the water was pouring out the air vent valve inside the bathroom.

I once tested toilet paper and yes it was a slow day for me : ) All the toilet paper that advertises "Septic Tank Safe" or "RV Safe" don't believe it's a just advertising BS to get you to buy their TP. I tested over 50 different brands, 1-ply, 2ply, cheap brands and expensive brands. Just a quit summary of my test. I pulled off 2 squares of TP folded it 3 times and placed inside a 1/2 gallon clear plastic container with regular tab water spout 3/4 full. I dropped the folded tissue into the water, place lid on, gave the container 2 shakes and let sit for one hour. After one hour I shook the jar 2 more times and then examine the TP inside. My findings was that most of the toilet paper was still intact with no broken pieces. You could literally remove the TP and unfold it without any pieces missing (bad). This is the type of toilet paper that will wrap around your sensors and get stuck in the groves of your dumping valve. There were other TP's that were broken up into smaller pieces (good). There was only a few of TP brands that actually disintegrated into small particles (excellent). Although I tested over 50 brands some of the brands had variations of the same brand and I'm sure there was another 50 brands out that I didn't test. I picked all the name brands and brands from Costco, Walmart, Sam's Club, Dollar store, Camping World etc. So it here it comes the best brand that worked the best for an RV black tank was "Angel Soft". I know there are folks that say that they don't care about what the wrong TP will do to there blacks that's that they have been using Brand X all their life and it is soft and creamy for their body and that's ok. I'm only giving options for the best toilet paper for your RV black tank. It's been about 5 years since I stated TP and I have been collecting TP again for another test. I will break it down to different plies, descriptions, cost etc. More to come around the 1st of the year. Another note is I have watched NASA testing process for testing different material in waste tanks. I also have a color snake scope I fish down the black tank and I can see my tank and sensors from the inside and can tell what chemicals works and ones that don't work. Some chemicals only cover the waste with perfumes so it smells nice but does nothing to break down the waste. When you dump you want to see just brown liquid and no chunky matter coming out. Some chemical will bark down the waste and it becomes just liquid. My background, I have own and traveled in RV's from coast to coast for over 22 years in Travel trailer, 5th Wheels and Class A motorhomes. I spend a few hours everyday researching info on good RVing. I belong to several RV website forums. A close friend of mine owned a RV mobile service.

So which TP is the one to get?

Angel Soft was one of the top selection for breaking into small particles when in your black tank.
