Hi. Here's a rough sketch of the plumbing for blowing ballast on my sub. I
plan on using stainless nipples as thru-hulls, with 1/2 inch valves directly on
the nipples, and a 3/8 air line tapped in to a ''T'' to blow the tanks/lines.
This is pretty rough, but it gives you the basic idea. Any comments? Frank
