It would take sixteen one-inch pipes to equal the cross-sectional area of one four-inch pipe. This assumes the pipes are circular in cross-section.
i would recommend any fmf piping
the best would be 1.75 inch
This pipe has a volume 437.4 gallons.
You wold join asbestos pipe and iron pipe with great care, being sure to avoid disturbing the asbestos pipe or releasing dust. The best solution would be to remove the asbestos pipe (following established procedures to ensure it is done properly, by qualified people) and run new pipe.
i think Ridgid 31005 8" Straight Pipe Wrench is best.
hose
Teflon Pipe Dope. Guaranteed I would have to either weld or braze the piping together
The best method for sealing pipe joints is using Teflon tape.
