Raptor 429 Holding Tank Setup?

I realize rear tank setup may be different, but looking for possibilities of whatís wrong as Iíve not received a response from Keystone on my inquiry.

Here is what Iíve determined with some messy trial and error:
-The coach is labeled with grey tank up front and black tank in the back

-The front tanks contain contents from Kitchen and Full Bath for grey and Full Bath for black

-The back tank (or tanks) contain contents from 1/2 bath

-The front tanks dump and drain as I would expect with the pull of the appropriate valve in the plumbing command center

-The back tank(s) appear to dump directly into exit pipe without any intermiediate valve to control release. In other words, the cap on the exit pipe is the only thing keeping everything contained.

Here is what Iím trying to figure out:
1) Is there an actual grey tank for the 1/ bath or does all content drain to a single tank?

2) Total capacity for grey and black are listed as 82 gallons each, but wondering if they are equal sized at 40ish apiece, or if front is larger than back?

3) Should the release valve that controls the front tanks also control the rear or are these typical configured as separate containment systems. I assume the latter, but understanding how it is supposed to work will help with my discussions with Keystone.

4) if not a central release valve for all tanks, is your 1/2 bath configured with a separate dump valve?

Iíve installed a pipe-end release valve but clearly want something more permanent and for this to function as intended. I know itís easy to miss things during construction or for failures to happen prior to delivery, so looking for collective wisdom to take this to the right place for resolution.

Welcome to the forum

Each waste tank should have its own drain valve. Itís been a running commentary that the tanks may be mis labeled. The only way to verify what each figure drains into is to empty everything. Then simply start running water until one of the tanks shows 1/3 full. Then shut that fixture off and start the next one.

This is the procedure I used for years doing PDIíd with multiple sinks/bathrooms and Washer/dryers.

If its a new model your 1/2 bath should all go into one tank with its own valve. Typically located behind the wheels on the drivers side. (a good distance from all the other valves)



If the cap is the only thing holding in the contents of the 1/2 bath, there is a strong possibility this valve is open.....
