Plumbing

There isn't much room underneath the cabin for drains, and not enough for larger sewer drains, so I had the cabin positioned with the toilet immediately over where the sewer line comes up through the concrete pad.  The other drains will tee into it just fine, with the multi-inlet drain fixture I special-ordered.

The plumber ran down 3 batteries cutting through that floor!

Then the trenching was done (the guys were backlogged horribly for a few months)

Sewer line

Water supply line (will be tied into the house waterline)

they had some fun digging around the phone line, but have obviously done this so much they just danced around it and went on.  It was lovely to watch, like a mechanical ballet.

That water supply line where it goes in under the house. 

They used the backhoe to push the cabin and line this all up.  That is the special fitting I got, but the cabin was pushed against it just enough that it can't be removed to glue, so we'll have to shift the cabin just an inch or so to the south.  The opening for the drain line is 2" larger than the drain, so there is some leeway in positioning.

The dark blue is the water supply line.  I wasn't paying attention when they placed it (I'd been up sick all night the night before and wasn't terribly alert that day) or I would have made sure they got it up into the cabin.  The plumber had drilled a hole for it, but I just completely forgot.  It looks to me like it wouldn't have lined up anyway, so we'll just cut it down and put an elbow fitting to get it out from under the drains area and over under the hole, then up into the cabin.  At least that is something I could even do if it really came down to it.

The greenish pipe sticking up with the white cap is a "clean out" access for any future sewer problems.
