Hi Gang,

I want to install a sink. The nearest pipe I can plug into is19 feet
away. The drain will be as follows:

18" drop from sink bottom to bottom of crawl space joists,

Run along bottom of joists for 19',

Rise 5" and plug into existing drain pipe within joists.

Thus, I will have no slope, but a 13" head. Will it work?

Thanks, Gary

I'm no drain mavin, but if I were doing the job for myself I'd put in a
tee and threaded plug under the sink and try and create the two 90
degree bends down in the crawl space with a couple of 45 degree elbows each.

That to make it easier to run a snake through the line if that long
horizontal run ever gets glogged with hair or something else over time.

I'll do that. Thanks for the suggestion.

Should be interesting.......

Technically, it will work.

Assume you won't be seeking any permits/inspection.

Perhaps he could convince the inspector that it's all one 19' long
trap.
