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.

Many '70's trailers had a single tank for waste water. My drain pipe cap has a 3/4" hose fitting for draining grey water into a tote or on the ground (whichever is appropriate).

My TC (camper) is a 1976 and it never had a grey tank. You can add one to the underbelly or just use the blue tote tank.

At a minimum the black has to have a valve and as long as it closed there won’t be any mixing, and the gray water will just drain into the tote… you could then drain the black into the same tote if you wanted to for disposal… if the gray pipe doesn’t have a valve, I would cut the pipe and add one so residual gray water doesn’t pour out when removing the termination cap…

johnny run water down your sink and see where it goes that will clear up what is happening

Would I see a tank mounted next to my black tank? Is it possible the grey tank is combined with the black tank (i.e. stacked, but compartmentalized)?

It was in the early 70s that gray tanks became mandatory, so yours should have been equipped with one. That's assuming that the rig was originally designed and sold as a travel trailer and not for some other purpose.

Our 1967 Airstream does not have a gray tank, so it's necessary to bring the blue tank (a portable gray tank in our case) or to have full hookups or to use a plastic tub in the sink and dump that into the toilet. (The rig is designed so that we can divert gray into the black with valves, but it's kind of messy, so we don't use that method.)

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.....

[JJBIRISH]

Its made to collect the gray in a tote tank…

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.

[dave17352]

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.
