No grey tank?

1983 Man-O-War 15' Travel Trailer

My kitchen sink and shower appear to bypass a tank and they pipe in right before the sewage drain.

Is the correct/legal? I suppose, if the exit is plugged, it will backup into the black tank.

It's had some work done, so I'm not sure if it ever had one or if this is a home plumbing job. All the plumbing hangs pretty low to the ground, I'm scared I'm going to bust it on a speed bump.

    Yea, he gave me a blue tote tank with the trailer. I thought that was for the sewage or something, and that I had a separate grey tank. Does grey and black water both go into the tote tank?

    EDIT: I guess I'm not sure where the grey ONLY hookup is.....

    I have had a couple old trailers and that is how it was done. You use to connect a length of hose to it somewhere and run it out on the ground. Now as far as being legal or not that will depend on the state you live in. I live in Idaho and last time I checked you could run grey water onto the ground. You will have to look it up and also in most campgrounds they dont like it to be done.

    Thats how it used to be done. Get yourself a blue tote tank to handle gray water. My 73 Terry was the same way. Can no longer dump on the ground so you do need a solution.

    It should be plumbed into a grey water tank for sure. Someone did a slop job repair. Pipe hangin low is not factory work. Sorry. This is where having a used RV checked over prior to purchase would have saved you on this.

    Sounds like you got a park model that was designed to stay hooked to a sewer line in a fixed setting. Designed to travel for transport to a site only.

    Maybe on that rig the grey water just ran to the ground they use to do that. Best to post a picture so people can see what you are talking about.
