“Don’t remember seeing the bill for that bit of cleverness but copper nickel piping for a flush terlet ain’t gonna be cheep.”
I would have to agree using a personal experience:
We built our small home in ‘95 but had been shopping & buying the ‘hard to get at last minute’ items (sinks, faucets, lighting, bath tub & toilets — the latter is the point of this post).
I managed to find at antique stores two old toilets, the new one from 1919, it has an Illini ceramic base with a copper tank just perfect for our small home.
I wanted to mount the tank ‘up’ on the wall and needed a copper tube (with a 90 degree silver solder to attach to the base). The exterior diameter was such that the only size of copper tubing that would work was only available for Navy subs - it has a very thick wall. A 5’ section with the silver solder was $600.
It still works like a champ 29 years later...That Navy plumbing is expensive!
5’ of Navy-rated tubing? Boy, did you get off easy. The typical sub uses upwards of 5,000 feet in various sizes. And your bathroom still couldn’t dive. But when you hit “flush” it might sound a bit like a ballast tank vent valve opening? You can visualize “dropping anchor.”
