tub p-trap

[Paul Mayeux]

Hi all, does anyone know the correct setup for the tub drain? My 62 Overlander has what looks like a standard p-trap under the drain and the problem is the belly pan was cut because the trap hangs down below the skin. Should there even be a p-trap there since there is no gray water tank?

Maybe the PO was backing the gray water into the black water tank. If so, the P-trap was definitely a good idea.

Same thing on a full hookup where you could get sewer gas backing up all the way from the campground pipe.

I would definitely keep a trap in the line.

I suppose some sort of cover is in order. Right now the skin is just cut around it to let it hang down. I can see that if it were not protected I would have to carry some extras along with pipe and glue for when it got ripped off. But I don't know how much protection some sort of aluminum box would offer. I do know that the .040 skin I used to replace the front half of the belly skin should protect more than the what the factory installed. That stuff was tough to work with!

In '62, the gray water would have simply run out on the ground or into a gopher hole and there wouldn't have been any odor problem or need for a trap.

You might be abl to move the trap to a more protected spot.

I'm not sure how much the coach has been modified but currently the grey water seems to come out of the valve that the black water tank is connected to. I don't know how this is set up because I have the black water tank full of water to check for leaks and it is holding fine. Did they have a dual function valve like this in 1962? I assume it is original. It has a black knob handle that is below the rear bumper and you pull it out to dump the black tank.

can you find a low profile p trap at a home fix it store?

i have a slop sink in my basement that i had to use one of these because of the low hieght of the drain.

they are kind of more of a "J" than a "P".

You DO need a trap; if you ever connect to a sewer, you'll be venting it into your trailer without one. maybe the REALLY old trailers had each individual fixture drain out onto the ground, but in mine, they all go to the same centrally located 3 inch sewer pipe, and connect below the level of the black tank valve.

my '73 (no grey tank) shower's trap has a plastic cover that extends below the belly pan. I never looked at it closely...just happened to notice this plastic cover in that general area, and I can only assume its for the shower drain trap. I though it was just an "inspection panel", but perhaps it is necessary, if the trap actually does dangle down below the belly skin.

Yes, I can see that not having a trap would stink (ha,ha). Anyway it sounds like mine is to is plumbed to where the grey water pipes converge at the black water valve. I'll check into the low clearance trap and fabricate a cover to go over it.
