[Alberg30] Thru-hulls

[Larry Morris]

Good lord you are going to all the trouble of replacing the seacocks and
you are going to leave the old thru-hulls.  Do you like doing the job
twice?  I would replace it all while you are at it.  Peace of mind is a
wonderful thing, especially when pounding into a heavy sea.

Merry Christmas

You can screw the ball cocks on to the straight threaded through hull 
fittings. Or you can use the flanged ball cocks by trimming the through
hull fitting 
length down so the screw into the seacock and draw up tight against the
hull.

One note when I replaced the gate valves I found that some of the
through 
hull fittings were made in two pieces. One piece was the threaded pile
and the 
second was a washer. These two pieces were fitted together via a
machined groove 
in the pipe where the washer was fitted then the pipe was expander to
capture 
the washer. One of these through hull fell apart when I tried to remove
it to 
rebed it. 

My advice is to get rid of any through hulls that don't appear to be one

solid piece.
