Washer drain in Carbon 357

Hi, these are probably dumb (2) questions, but it seems that my washer drains into my rear black tank. Question #1, why?? Why would a company drain a washer into a limited capacity black tank and not into gray or directly to the termination valve??
Question #2- is there any way to reroute where the washer drains?
Thank you for any help or tips you can give this Newbie!

If your washer drain is in the garage then the black tank is closest. I've not checked but I would imagine mine is set to drain the same way. My kitchen drain is the only thing that drains into my second gray. Rerouting is always possible but the elevation of each may not allow it.

Just a thought here, but if it really bothers you that much then cut the connection to the grey tank, seal it off and build your own leading to a second
"termination valve." Granted you would have no holding tank for the washer, but not many campers I know wash clothes when they are boondocking.

If your TH has a bathroom in the garage, then there isnít enough space underneath for another holding tank.

Ours has 2 gray and 2 black. Has a bath and half, full kitchen and washer in garage. They drain the washer to the rear black.
I think it's not such a bad thing. We seldom use rear toilet, as I think most do. For us full time living and we use the washer ( Splendid 710xc ) about every day she to its small capacity. The blacks fill at about the same rate. And one benefit as well,, the detergents in the wash waste water cleans the rear black tank well. The rear black tank sensors seldom get 'hung up'on the level indications

I've got the 327. Two gray tanks, one black. It drains into the rear gray tank.. Basically whatever tank is closest and cheapest.

Assuming you're not actually using the rear bathroom, just put a valve on the output of your drain, open the black tank, open the gray tank... essentially you've got more capacity.

Good idea. I don't know how to add a valve, but it is worth looking into.

So which tank is black 1 and which is black 2? I emptied them both but the light indicators say one tank is still 2/3 full. Why would it do that? Is there anything I can do to fix it?

I would love to do that but first off it is out of my expertise, second I dont want to void a warranty.

You probably have a piece of toity paper hanging on a sensor. 3 things to do:
1. Use more water when you flush.
2. Use the black tank flush to fill and empty till clear.
3. When you pull out, add several gall OK ns to the black tank and some Dawn. The agitation of rolling down the road will help clean the sides.
