That seal is only so tight. Plus you might not know till you hit the flusher and some comes up.

Put a twist-on sewer dump valve on the common? sewer drain. Leave it closed. Open the black water and the gray water drains. Problem solved - the gray water will enter the black tank and both tanks will reach the same level. To drain, attach your hose and open the twist-on valve. Of course you must have a "common" drain point.

Point- you can always drain the grey water somewhere safe. The kitchen sink is one of the major grey water sources and if it fills up the black tank you can't dump it in the grass like we used to do in out old Pace Arrow

Definitely not allowed in many places. :(

The more water you get into your black tank the better, most people do not put enough in the toilet and that is a major cause of problems.

You should be checking your tank levels periodically so there is no reason that your tank will back up anywhere much less into the sink or toilet, unless you just don't check them.

and yes, for many manufacturers, and different floor plans, it is normal

That is a good question.

i agree, that would be a deal breaker for me
my second rv had bathroon sink drain into black, filled it much faster and required more frequent dumping when dry camping or water only hook up camping
my latest rv I checked before purchase to be sure black was black and grey was grey

live and learn.....

This would 'contaminate' your gray water though and you wold want to be sure to fully flush it and maybe sanitize it well if you ever dump the grey in the grass/drainage.

Our 98' Seabreeze is setup like this. The kitchen sink drains into the black water tank. After we figured this out, I think it's a good idea. As posted here, many people do not get enough water in the black water tank if it is isolated and could cause clogging upon opening the valve. The DW uses one of those little scrubber things that holds dish soap in the handle. She now uses very little water doing the dishes. When boon docking, she cam wash dishes in a large plastic bowel inside the sink and where allowed, dump out the soapy water outside. That way, only the water from hand washing and dish rinsing adds to the black tank level. You just have to be more conservative on alot of things when boon docking or dry camping.
