Re: lubricator piping
Things I hadn't thought of. Thanks Harry.

Terry, Because the steam line can be replaced, and in the event of a failure a broken lubricator line wouldn't release the entire contents of the boiler in an instant. By the way, I would never recommend using salvaged copper tube, such as out of an old house, for a boiler. Sanitary drains piping was usually done in type DWV copper which is the thinnest grade made and you could never be certain that it was OK structurally. Then, you would have to work so long on it to clean the crud off to the point where it would take solder that it wouldn't be worth whatever you'd save. Regards, Harry Ohio Department of Health

Re: lubricator piping
Not that I want to open a can of worms, but... If using Brass in a Boiler is a problem, due to enbrittlement, why is it okay to use brass for a steam line? I would think that the steam would still have the ability to absorb the Zinc from the brass, and a steam line would be under the same pressure as a boiler, if not slightly higher if there is a superheater fitted.
