[Public-List] Seacocks and gate valves.

[John Flanders]

Randy,
My 1-1/4 gate-valve has yet to yield to the pipe wrench, but I will  
try again. In the confines of the sink locker, it is hard to get a  
sustained push. I am thinking about using a propane torch to loosen  
the joint up a bit. I would appreciate your pics.
John
