[Public-List] Standpipe exhaust

[mahseer at kos.net]

The copper stand pipe is 3in dia.  when I did mine I purchased a 3in
copper coupler then after scribing an alignment line cut the pipe.  After
checking I just soldered them together,  the coupler was purchased from my
local industrial plumbing coumpany.
