Crack. THUMP! Woosh~

Does anyone know what this material is that connects the pipe? It is rubbery / clay like.

Hearing stories like this makes me worry about my camper. The tanks are simply hanging under the overhang on the back supported by two cloth straps with a screw at each end.

great to hear the pictures helped. I hope the repair goes quick and easy at the dealer for you.

Good luck Matt! Two weekends ago I had a "Bam!" and then a "hummmmmm" and a muffled sound of faucet running. Ran to the water pump switch to turn it off. Turned out to be a water line to one of the kitchen faucets had burst and was pouring out inside the cabinet and running out more or less the bottom of the camper. Boy would that suck if it happened when you weren't around. Good reason to always turn off the water pump when not in use.

Update:

Thank you Rich for pointing out the access panels. I had no idea and yes I have them like you.

Based on the newly discovered access panel I was able to reach the broken pipe. While this is the inflow from the bathroom sink, it is also the low point on the tank (they are sloped to help draining). I am guessing since the tank was at 100% capacity (or very near), creating an opening in the top would allow a fair amount of volume to drain out.

I tested the other inflows (kitchen sink & shower) and there does not appear to be any additional leaking, leading me to believe this is the only break.

I also closely examined the black water tank (visible from the exterior access door) and it appears to be resting on the frame. I can not see any evidence of any strapping, indicating it is suspended. I can see about 80% of the tank (top, part of the bottom and two sides). I can also see about 10% of the grey water tank through this access door and it to seems to be sitting on the frame.

From the interior access panel shown below (the pipe in question is the bottom or left pipe), I can get a fairly firm grip on the now empty grey water tank. I can not move it, giving me some confidence that it is sitting firmly on the frame as intended.

If this is true, there must have been some unintended upward pull by the bathroom sink inflow pipe that is now separated / pulled away from the tank. There is a 1/4" gap between the pipe and the tank giving me further confidence that this is an isolated issue and there has been tension here for some time.

Given all of this, the fix would be rather easy=Cutting the inflow pipe, adding a longer length to reach the tank and reseal; however, I do have an extended warranty and the benefit of an Adventurer dealer nearby. I think I will get a second opinion. I have an appointment next Monday.

Finger's crossed this is the scenario and the repair goes quickly. My worst fear is any delay in the 2013 camping season.

Thanks everyone

you do have a different year and model than me but ill post these pictures anyway. do any of your wall panels pop off like this for access on your camper?

Some brands suspend the tank with a metal retaining strap. It sounds like your was suspended like that and came loose. A few people have repaired theirs and posted pics. You might be able to find some examples by querying the forum or archives. If I remember right, you have to take the floor off to gain access. Otherwise, it's adding extra support for the tank by adding screws or more straps to support the tank.

I have never had an Adventurer basement apart but i have had and seen other mfg.'s apart. IMO, it appears to me that there is not a a lot of clearance to build enough support members to hold heavy things in place. Some campers might be better than others but for the most part, i have seen full water and holding tanks drop down while off loaded .
