Okay, picture sizes fixed...
After spending a little quality time with Lil' Queenie under her shower, and messing around with her drain pipes over in "Bathroom Remodel", I'm returning here to "Waste Water" to cover some details on how the trap systems are going to work out in the camper.
We'll get to the galley system later - and the picture of the shower result is in "Bathroom Remodel", but here's a detail discussion and assembly of the bathroom sink trap on the warm side of the camper in the battery compartment - right above the grey tank.
These are the players.
The suggestion by ticki2 to go with worm gear clamps found on Fernco adapters is good. I've liked the idea every since he mentioned it. But I found difficulties arise from the inside and outside diameters in adapting standard 1.5" PVC Schedule 40 pipes and fittings, and the 1.5" (typically kitchen sink and tub/shower) trap pieces!
Notwithstanding potential availability in mobile home and other RV parts, the residential home centers and standards seem to only provide the nut and washer design "trap adapters" I was trying to avoid. Also, the tiny spaces available to my particular design were proving quite a challenge.
Most particular to this recent work was the elbow pieces, that is to say the part of the trap assembly that goes between the p-trap itself, and the wall adapter. In my case I was at a store that didn't sell the pieces separate, so I had waste. This is a shot of what I DIDN'T use (or won't be using as I complete the gally area).
But if making a homemade basin nut made anybody smile, ;) this next job may have you ROTFLYAO.
Incidentally, after all was said and done, I finally realized the black Fernco parts are for standard plumbing sizes, and the grey are for trap sizes. Doh!
This was the first adaptation. Cutting a p-trap into a usable elbow of trap diameter.
Making the players now thus.
And when assembled, looking more like this.
So that was the theory anyway. Now let's try and prove out the hypothesis.
First step, remove the previous design. By doing this I could again have a tank connection that can be worked on without disturbing the tank, like I did on the shower connection.
Then I stubbed in the tank connection. When I ordered the tank I was thinking in terms of 1.25" for bathroom sink and 1.5" for all others. So this connection is 1.25" and I'll be clamping onto it's OUTSIDE diameter, instead of inside, as this piece was designed for. In doing so, I scraped off the raised lettering and a little casting nub and smoothed the outer surface for the clamp connection, which fit perfect.
And it all came together like this. I had to flip the one piece from what had been planned on the bench a minute ago.
Those are group 27 batteries by the way. The group 31's on the wing are too big for them AND the power distribution center depth.
Now when it comes time for completing the galley sink trap and vent, I have the parts standing by.
And you might also notice, using a black Fernco 1.5" to 1.25" coupler between the PVC and copper, gives a good fit without compressing as I showed and didn't like some time ago.
